⇒ 'PBW cleaner' (and why you should use it)

PBW stands for Powdered Brewery Wash

PBW cleans beer equipment very well

PBW by Five Star originated in commercial breweries like Coors then found its way into homebrew circles for its unique blend of sodium metasilicate, sodium percarbonate and nonionic surfactants. That trio saponifies fats, chelates minerals and lifts proteins and hop oils from metal surfaces.

Don’t take our word for it. Hunt “PBW review” online or scan brewing forums and you’ll see pro brewers and hobbyists alike credit PBW with stripping rock-hard trub and beerstone without harsh fumes or steel pitting.

🧼 The benefits of using PBW are many

Key Takeaway: Deep-clean via saponification and chelation
Best For: Beerstone, trub, organic residues, label removal

• Burnt-on trub dissolves as sodium metasilicate converts fats into soap—run at 60–70 °C for faster action and shorter soak times.
• Beerstone (calcium oxalate) chelates into solution, outperforming pure acid cleaners on tenacious mineral scale.
• Gentle pH balance and nonionic surfactants prevent metal corrosion—ideal for stainless steel, glass, plastics and rubber.
• Biodegradable percarbonate makes PBW septic-safe and eco-friendly—rinse water can go straight down the drain.
• Sodium percarbonate doubles as a laundry booster—brands like Napisan and OxiClean share its formula, so DIY alternatives abound.
• Mild on skin compared to sodium hydroxide, though protective gloves and goggles still advised for concentrated soaks.
• Peels labels effortlessly: soak bottles overnight to remove adhesive and paper fibers without aggressive scraping.

🔬 PBW has plenty of uses you might not expect

Left dried krausen and spent yeast in bottles? A few hours in PBW solution flushes out sediment your brush can’t touch.

Forgot to clean that fermenter until residue hardened like Fort Knox? A full-strength overnight soak then a hose rinse restores it without a brush.

Dishwashers and washing machines benefit too—run an empty hot cycle with PBW to clear grease, soap scum and funky odors.

⚙️ It’s really easy to use PBW

Ratio: 1–2 oz per gallon for kettles; 1 oz per gallon for fermenters, kegs and carboys
Method: Hot water soak, 4–12 hours, rinse

1. Heat water to 50–70 °C, stir in PBW until dissolved.
2. Submerge equipment fully. Agitation or gentle swirling accelerates penetration.
3. After 4–12 hours, drain and rinse thoroughly—no scrubbing needed.

💬 So what do other users say?

Amazon reviewers give PBW 5 out of 5, praising its ability to cut through protein, wort sugars and hop oils in one go.

🧹 PBW is not a sanitizer

PBW removes soils, it doesn’t kill microbes. After cleaning, switch to a no-rinse acid sanitizer like Star San to avoid contamination.

🔍 Active ingredients in PBW

Sodium Metasilicate (≈30 %): Turns fats into soap, breaks protein bonds and disperses mineral scale.

Sodium Percarbonate: Releases oxygen for oxidation cleaning and chelation; also sold as laundry booster.

DIY substitute: Blend 30 % TSP/90 (Red Devil) with 70 % OxiClean for a close match to PBW’s dual-action formula.

🛁 Soaking kettles and pots

Neglected trub can bake onto your brew kettle. PBW at 1–2 oz/gal and 60 °C for 6–8 hours dissolves organic deposits, protein films and beerstone so you can rinse with a hose and be ready to brew.

🏠 Other household uses

Clean kitchen appliances—stove tops, oven trays and fridge interiors—by applying PBW solution with a cloth, then rinsing.

For a deep dishwasher clean, run an empty hot cycle with PBW to lift grease and clear spray arms.

📊 Pros and Cons

Pros	Cons
Effective Cleaning Dissolves organic residues and beerstone	Cost Pricier than generic cleaners
Safe on Materials Gentle on steel, glass, plastic and rubber	Safety Precautions Gloves and eye protection recommended
Non-Hazardous Formula Biodegradable, no harsh fumes	Environmental Disposal Requires proper rinse disposal
No Scrubbing Oxygen-powered action lifts soils	Rinsing Needed Thorough rinse necessary to prevent off-flavors
Versatility Cleans kegs, fermenters, laundry machines and more	Preparation Must monitor temperature and concentration

🛒 Where to buy PBW

Find PBW on Amazon in multiple sizes—ideal for occasional hobbyists or brewery-scale use.

❓ Acid sanitizers vs Covid-19?

Star San’s low-pH, phosphoric acid formula can inactivate enveloped viruses in lab settings, but it isn’t certified for medical disinfection. Always follow CDC guidelines and use approved hospital-grade disinfectants for virus control.

For brewing, stick to PBW for cleaning and Star San for sanitizing—neither replaces a dedicated virucidal agent in healthcare scenarios.

What is the best homebrew sanitizer?

Chances are you found this page because you are looking for the best sanitiser to use with your homebrewing.

Smart move, brewer.

You know why right?

You know because every decent beer maker knows that to make a good beer you need to have all your equipment and bottles sanitized so that your brew is not spoiled by nasty bacteria.

Have you ever had a batch ruined by a lack of proper cleaning or sanitization?

It’s a real bitch when that happens.

So then, let’s cut to the chase.

Here’s a list of what are the best sanitizers to use when making beer or even cider or wine.

Choose what you want but no whining about ruined beer if you don’t properly prepare your gear before you make that wort!

Star San - the best comes first

If you want to use a product that will destroy all the microorganisms that could screw up your beer, then Star San is the sanitizer for you.

It's described formally by the manufacturer as "a self-foaming acid sanitizer ideal for brewing, dairy and other food and beverage equipment."

It is an extremely effective bactericide and fungicide and is not affected by excessive organic soils. Star San also reduces water spotting and can be used without rinsing under the proper concentrations. STAR SAN is a blend of phosphoric acid and dodecylbenzenesulfonic acid."

So as bonus then, when using Star San there is no need to rinse it from your beer bottles or the carboy when can be pretty handy when all you wanna do is make beer!

One can use Star San as a spray on or for soaking gear and beer bottles. Used at a ration of one ounce to 5 gallons of water it will do a damn fine job of keeping those bacteria at bay.

It is probably the most well known and well recommended sanitizing product known for home brewers.

This bloke said of his use of it in his Amazon review:

"This works great and is very easy to use. I just followed the directions on the bottle and had no issues. I like that it doesn't have to be completely rinsed just allowed to dry."

The only down side is that the manufacturer knows this and you can be charged an arm and a leg for it!

Iodophor

Iodophor is another popular sanitiser adopted by the beer brewing community. Iodophor has been traditionally used by the food service industry and medical industry to sanitize equipment but it works just fine on your brewing gear.

Iodophor is a three-things-in-one iodine product. It's a detergent, germicide and sanitizer.

The solution takes approximately 10 minutes to sanitize your equipment and like Star San, it's a no rinse product when used at the recommended concentration.

This Amazon review is telling:

"I had been using bleach to sterilize my stuff but too often had bleach aftertaste in my beer. Since moving to BTF Iodophor, my batches taste great and have the hoppy aftertaste I want and not a mix of hops and bleach."

It is a good idea to keep it away from your clothes because it will stain them. So wear old clothes when preparing your solution and be careful!

That said it is odorless, tasteless, and easy on your hands.

Powdered Brewery Wash known to many as PBW

This cleaning product was originally used widely used in commercial breweries (hence the name) but over time countless home brewers across the country have cottoned on to how they can use it for sanitizing their brewing equipment. 

It's one of the most commonly used sanitizers and for good reason as it works!

Go onto any beer brewing forum and you will find seasoned beer makers raving about this product.

Go on, Google it now and you'll quickly find we are not exaggerating about how good this cleaning product is. If you are looking for some guidance about how to clean your brewing equipment, they will probably say use this powdered wash.

PBW is also pretty handy for removing beer labels from bottles and so is alkaline brewing wash.

Make your own substitute PBW with basic ingredients

You can also make your own version of PBW as a substitute using ordinary home products.

Basically what you do is combine a home brand like Tide, Oxiclean, or Napisan with a product that has metasilicate as an ingredient - we've found that many home DIY brewers use a cleaner called Red Devil TSP/90 to fill that part of the equation. Mix them together in 70 / 30 ratio in favour of the laundry soak and you've become a home DIY sanitizer!

Now this last one is a perhaps a bit of a surprise, however, it's tried and true for many home brewings.

Are y'all ready for this?

Laundry soakers as sanitizer

That's right, it's probably already sitting on your laundry shelf...

Here's a handy trick, this chemical is basically what you might know as Tide or Napisan or any product with a brand name that tries to use the word 'oxy' as in oxygen cleaning or oxidization agent.

That's right, most of the fancy laundry soaking products have sodium percarbonate as a key ingredient!

Chances are you already have some in your home laundry so feel free to use that.

I have done so several times with no problems whatsoever!

Bleach

When I was a young lad I used to work as a cleaner in a butchery. Once of my jobs was to clean the bin which housed all the meat scraps and bone that could not be made into mince or whatever.

That bin sat outside all week until Thursdays when it was emptied and then it was my job to clean it.

Because you know, maggots.

So I would prepare a bleach solution to clean it out, kill the maggots and most importantly get rid of that smell that was created when the hot sun beat down on that damn bin all week.

One week, I accidentally kicked the bucket of bleach solution over, and it went all over one of my brown boots.

No big drama right?

No drama until I looked down a short while later and my boot had turned mostly orange.

And that's when I learned truly the power of bleach!

But brewers have known for much longer that bleach can be used to clean home brewing equipment.

It's pretty cheap, readily available at supermarkets and it does the job of clean bugs and bacteria in its path.

All you need to do when using bleach is to make up a solution with the ratio of 1 tablespoon of bleach to 1 gallon of water ( or 4 mls per liter). You then need to soak for about 20 minutes and the santization should be done.

The thing about bleach though is that it can have a bit of a strong pungent smell. While at the suggest use ratio, you probably don't need to rinse it off your gear, we strongly recommend that you do.

Given that Star San is pretty much good to go after less than a minute of contact, we suggest that if you can afford it, you use that and don't muck around with bleach.

It might stop up from changing your shoe color too!

-

There are other options out there too - caustic soda, using boiling water, cooking in an oven and using an autoclave etc.

So there you have, there's plenty of choices out there for the best homebrewing sanitizer. To our mind, it comes down to three areas of choice:

• The more you spend, the better the quality and ease of use - so it's clear then that PBW and Star San are the best bets there 
• If you are looking for a mid range price, try a product with sodium percarbonate 
• If you want cheap and cheerful with a longer sanitization time, you'd go with a standard bleach. 

In the end, all roads lead to Rome! Clean clean clean!!

Is 'Alkaline Brewery Wash' better than PBW?

Alkaline.

It's a great word. 

It just rolls off the tongue so easily

And if you want to easily clean the sludge and muck off your homebrew equipment, then alkaline brewery wash might just be the magic cleaning powder you are looking for.

Some brewers claim it works even better than PBW!

The benefits of using alkaline wash include:

• Cleans effectively in cold or hot water
• Works longer than oxygen based cleaners as it doesn't break down the same way
• Can be used to remove troublesome bottle labels
• Does not leave a chalky residue as it reduces calcium carbonate and oxalate residues that oxygen based cleaners tend to leave behind
• Powdered formula will eat through carbon build-up
• Safe to come into contact with skin as it is non-caustic but we'd recommend you take precautions such as using safety gloves and avoiding getting it in your eye.
• It's safe on glass, plastic, and stainless steel but avoid using on aluminum as it will react with it

One of the most popular washes is the Craft Meister ABW, check out the price on Amazon.

How to use alkaline wash on brewing equipment

You can use it as a spray from a bottle or do a soak. Many brewers like to leave their equipment soaking overnight to ensure it really gets the job done.

It works on kegs and carboys, kettles with no issues. 

Given the washes ability to dissolve organic matter, it works really well on bottles when you need to get rid of that sludge that gets left at the bottom - especially if you don't clean a few for a while and it dries out. 24 hours in an alkaline bath will sort them out, ready for bottling day. 

It will also work wonders on your glass wear!

A user that brought this product online from Amazon said left this short but handy review:

"It seems a little better than PBW. I've used this to clean brewing equipment, as well as to soak and scrub etching marks from drinking glasses. A very effective cleaner."

How much wash do I use?

• For equipment like fermenters and bottles use 1 oz (2 scoops) per gallon of water.
• For heavier jobs like brew kettles use 2 oz (4 scoops) per gallon of water.

Is Craftmeister's Alkaline Brewing Wash better than PBW?

While both products are quite similar in their make up, there's some debate. Many brewers sweat it performs better than PBW, especially in cold water.

It's more expensive so you have to weigh it up - what's worth more to you time or cost savings? If you want to use a cheaper product, use a sodium percarboante laundry soak. 

This quote from a forum sums things up nicely:

"Yes, it's pricey, but holy cow this stuff is magical. I've been pumping it around my rigs for years but you can't see the inside of a hex to appreciate how well caustics can work."

Another committed user said:

"This cleaned spots in my glass carboys that PBW could never get rid of"

So what are you waiting for? Check out the price on Amazon.

What are the active ingredients of Craftmeister's alkaline wash?

• Sodium Carbonate 50-65%
• Sodium Metasilicate 30-40% 
• Sodium Sesquicarbonate  ≤ 5%

On the safety certificate, National Chemicals (who produce the brand) state there are some other ingredients that are nonhazardous but are of a propriety nature so they do not disclose their full composition.

It's important to note that many other products out there are referred to alkaline wash powder for things like foot fungus and eczema. These products are made of different chemicals!

Recipe for making a substitute PBW beer equipment cleaner

There are many facets of beer making that are important:

The right hops.

The right temperature at which to brew.

The right yeast.

The right sized kettle.

The right whatever else you think is important.

But as any cook, painter, website designer or astronaut will tell you, preparation is the key to success and the father of successful brewing is making sure that your beer making equipment is clean!

We've previously recommended PBW as a literal solution to cleaning your brewing equipment as it is a proven cleaner and degreaser.

But as a branded home brewer product, Powdered Brewery Wash can cost you some real cash money. Many brewers swear by and believe in its value but if you are looking to get a substitute product at a cheaper price, there's a handy wee trick you may wish to try to make your own version of PBW.

What you are going to do is replicate the two main ingredients of PBW to make your own recipe.

We are looking to source these two active ingredients found in PBW.

• Sodium percarbonate 
• Sodium metasilicate

So where does one find these ingredients in home products?

The good news is that you might already have the percarbonate on a shelf in your laundry at home!

Many washing machine soaker's main ingredient is based the chemical we are after, sodium percarbonate.

Examples of the brands we are talking about are the household names such as Tide, Oxiclean, or Napisan.

For the metasilicate, we've found that many home DIY brewers use a cleaner called Red Devil TSP/90. You can find it on Amazon or local stores such as Walmart, Lowes or Home Depot. Sparklebright is also well known for containing TSP.

The TSP stands for tri-sodium phosphate. That chemical is not actually used much in America due to environmental concerns so the TSP/90 is actually a substitute product, hence the meta-silicate!

Confusing much?

So how to prepare this combo?

Now, mixing chemicals found in the kitchen or laundry can be dangerous but we are not using chlorine or ammonia here so we are on safe ground to mix our formula's ingredients.

The ratio to prepare is 70% Oxiclean with 30% TSP/90 - by weight. This ratio gives you your DIY version of PBW.

How much powder to use?

The concentration is 1 ounce per gallon of water which equates to 30 grams per 3.5 litres which is basically about 10 grams per litre.

Safety precautions

While Red Devil TSP/90 contains no phosphorous, lye or other abrasives and the laundry soaker is pretty benign, it is prudent to use protective gloves during use. This is because the chemicals are alkaline and contact with your skin is not recommended.

You can then use your cleaner in the usual manner to soak and scrub your fermenter and other brewing equipment. 

You can also wash beer gear with dish washing liquid to get gunk off first.

↣ What is beerstone (and how to remove it)?

Beerstone is a silent but deadly beer gear killer

It creeps in slowly, like a silent assassin and you might not discover their presence until its too late...

Beerstone

The scourge of brewing kettles and kegs everywhere, beerstone can be a key element in causing off beer.

What is it?

Beerstone is a kind of scale known as 'calcium oxalate' (C2CaO4) in the brewing industry. 

This precipitate is largely due to a reaction between alkaline cleaners (e.g. caustic soda), hard water minerals (think calcium and magnesium) and protein in the form of amino acids.

It affects both the home brewer and commercial operations. 

Perhaps unsurprisingly once you've learned about the science, the milk industry has similar problems with buildup on milking machinery and milk vans.

That industry calls it, yes you guessed it, milkstone!

How does beerstone ruin beer?

The development of beerstone leaves an unsanitary surface on the keg or kettle or other brewing equipment that offers an environment that can harbour microorganisms. 

At it's most minor interference with the beer, beerstone can cause those classic "off flavors" or even shorten the shelf life of your batch.

In the worst case scenario, unwanted micro-organisms can wreck an entire batch of beer which is a waste of good beer, a waste of money and a loss of your precious brewing time.

How does beerstone form?

The organic compounds found in the wort and beer will combine with metals in the water - usually calcium and magnesium for the oxalate. It is a white, crystalline precipitate - which makes its initial appearance hard to detect with the naked eye. 

Beer bugs will then find a home in the calcium oxalate - and here's the kicker - this environment allows the microorganisms to avoid contact with your cleaning regime and, believe it or not, sodium hydroxide (NaOH) can then help form a cover by creating additional precipitate because the caustic agents react with the CO2 (given off by the fermentation process).

It's almost like you can't win!

So how do you remove beerstone?

The pros at Birkocorp have offered a pretty handy 5 step method for removing beerstone build up:

1. Rinse out beer and yeast with ambient temperature water.
2. Use a 1-2 ounce per gallon phosphoric/nitric acid mixture (140°F maximum temperature) for 15-30 minutes.
3. Do not rinse the solution out.
4. Use a noncaustic alkaline cleaner at 1-2 ounces per gallon of warm (120-140°F) to start. CIP for 15-30 minutes depending on conditions.
5. Rinse with ambient temperature water until the pH of the rinse water is neutral (same pH as the tap water coming in).

If it's not clear, you'll need to fire up up your gas burner to get the solutions to the correct temperature.

Any residual 'soil' adhered to the metal can be removed with a high-pressure hot water rinse or simply wiped off as it should now be quite soft. If you need to do a scrub, use a sponge or scrubber that will not scour the metal. 

The entire method should be followed. This is because the acid mixture does not remove the stone, it softens up the scaling so that the alkaline cleaner has the chance to do its magic. 

Beerstone Prevention is beer than cure

If it's so easy for brewers to not notice that beerstone is 'scaling up' how can it be prevented from occurring?

The key is to mix up your cleaning method by using strong acid solutions are the quickest and most effective way to remove beerstone from stainless steel surfaces. Hydrochloric acid is a popular choice but you should not use it every time as it could cause pitting.

When using strong acids, be wary of their corrosiveness on metal.

Brewclean is a product that can help prevent the buildup of brewstone. Specifically designed for cleaning homebrew kegs and brewing equipment, it is non-corrosive so it will not cause rust on kegs or other homebrew equipment.

The wetting agent (surfactant) helps remove beerstone and other 'soils'. It's a good alternative to using sodium hydroxide.

You should be quite careful when using these kinds of acids and alkaline solutions as they are pretty potent and can do some real damage if you come into contact with them.

 A splash of chemical cleaner in the eye is pretty damaging and painful, trust me I learned this lesson some years ago and it cost me a trip to the hospital!
