As a homebrewer, you will have to spend considerable time, money, and effort in cleaning and sanitizing your equipment.
After all, you want your brew to be as pure and fresh-tasting as possible, don’t you?
Although your typical household cleaning products might seem adequate for the job, there are many reasons why you should opt for brewing sanitizers and cleansers instead.
Products specifically intended for cleaning brewing equipment won’t have perfumes that can affect the taste of your beer.
They also don’t contain surfactants that leave filmy coatings in the interior of your system.
The good news is that there are many options in finding the best sanitizers and cleansers that can clean your equipment more efficiently than any household product.
Here, we review five of the most effective products available on the market.

What’s the Difference Between Cleaning and Sanitizing?
Before we get into the different brands, it might be worth outlining the difference between cleaning and sanitizing. Although the terms are often used interchangeably, they actually refer to two distinct functions.
“Cleansing” simply involves removing dirt, grime, and residue that collects in the equipment. “Sanitizing” on the other hand involves eliminating bacteria, mold, residual yeast, and other types of contaminants. 
Why is it so important to make the distinction?
The best sanitizers will, but they aren’t nearly as effective in getting rid of debris.
In order to get your brewing kit totally clean, you really need a good brewing sanitizer AND a good cleaning product.
“Cleaning a surface simply removes visible debris, dirt and dust. Sanitizing a surface makes that surface sanitary or free of visible dirt contaminants that could affect your health. Sanitizing is meant to reduce, not kill, the occurrence and growth of bacteria, viruses and fungi. Disinfecting a surface will “kill” the microscopic organisms as claimed on the label of a particular product.”

Our Top 2 Cleansers as of February
#1 Five Star PBW (Editor’s Choice)
Five Star PBW cleaner is a buffered alkaline detergent that is a more effective cleaning solution than caustic soda cleaners.
A unique blend of buffers and mild alkalis, it is especially effective at cleaning stainless steel, aluminum, and even plastic. It also won’t cause adverse skin reactions, so it is totally safe to use.
PBW cleaner uses active oxygen that effectively penetrates carbon or protein soils, so it can be used effectively even with hard water.
The oxygen also reduces BOD and COD in wastewater, making it a more environmentally-friendly cleaning solution than most other alternatives.
In actual use, this beer bottle cleaner has proven to be a low-residue and clean rinsing solution that leaves no trace of odor. Brewing equipment comes out spotless, with no hard water marks left behind.
For the money, you simply can’t find a better cleaning solution than Five Star PBW.
- Strong and very effective – more effective than other soda cleaners
- Biodegradable – environment-friendly
- Makes your equipment squeaky clean – won’t leave hard water marks
- A bit pricey – more expensive than other brands
#2 One Step No-Rinse Cleanser
One Step No-Rinse Cleanser is an oxygen-based cleaning product that comes bundled with a number of starter brewing kits.
Although originally marketed as a beer sanitizer, it has since been reclassified as a brewery cleaner due to its inability to secure FDA approval.
In any case, the One Step has proven to be a fairly effective beer bottle cleaner, certainly more so than most other products marketed as sanitizers.
The solution is pretty strong, and does a good job of cleaning out most debris from brewing kits.
- No-rinse cleanser – no need to worry about residues
- Strong cleaning solution – effectively clears out most debris
- Competition is high – there are other more effective cleansers on the market
- Unclear marketing – there is some confusion as to whether or not it can be used as a sanitizer
Our Top 3 Sanitizers as of February
#1 Star San (Editor’s Choice)
Star San is a no rinse sanitizer that is an effective response to home brewing sanitation needs. The solution foams up nicely which enables it to reach into the deepest cracks and crevices in your brewing equipment.
With this beer sanitizer, you can be sure that all contaminants will be totally eliminated from your brewing system.
Star San Sanitizer is quite an economical brewing product. Mixed with distilled water, the resulting solution can be used many times over.
The manufacturer recommends placing the solution into a squirt bottle so you can apply only as much as you need at any given time.
As far as homebrew sanitizers go, you simply can’t do better than this product.
- Effective foaming action – gets the solution into cracks and crevices
- No rinse sanitizer – for your worry-free sanitizing
- Colorless and odorless – does not leave a strong scent
- Economic – can be reused several times
- Has no moisturizing property – may dry out the skin
#2 Five Star IO Sanitizer
Five Star IO is a low-foam iodophor sanitizer that doesn’t require rinsing afterward.
The product is meant to be mixed with water at a ratio of one ounce of this product to five gallons of water (cold or lukewarm water may be used). However, this usually results in an overly-strong solution.
The resulting solution gives you 25 ppm of titratable iodine. The manufacturer recommends two-minute contact for sanitation purposes. This iodophor sanitizer does not cause corrosion in steel or copper.
- Non-foaming solution – less messier
- No rinse sanitizer for brewing – for easier sanitation
- Easy to use – you can easily tell when you’ve added enough IO to the water
- Unclear instructions – following it will result in an overly strong solution
- More time needed – requires two minutes of contact time
- May not be 100% reliable – loses effectiveness over time
#3 Clorox Bleach
Clorox bleach is of course a familiar household cleaning product that is often used for kitchen and bathroom surfaces, fixtures, implements.
Bleach is so potent and economical that only a few drops in water are required in order to make a pretty strong sanitizer.
Unfortunately, bleach isn’t really a feasible homebrew sanitizer solution.
When used in brewing equipment, you will have to use a lot of water to flush out all the traces of bleach. This takes a lot of time and wastes a lot of water.
Furthermore, contamination is still a possibility unless you use water that has been sterilized beforehand. And of course, there is also the risk of getting bleach on your clothes and fabric surfaces, causing unsightly spots.
- Budget-friendly – cheap and easily available
- A strong sanitizing solution – no residues will be left
- Requires thorough rinsing – due to its strong solution
- Resource-hungry – takes up a lot of time and wastes a lot of water
- May not be skin-friendly – irritates skin when used
