What’s the Best Homebrew Sanitizer & Cleaner?
The Top 5 Products Reviewed

Here, we review five of the best and most effective sanitizers available on the market.

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.

What’s the Difference Between Cleaning and Sanitizing?

cleaning and sanitizing equipment

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. [1]

Why is it so important to make the distinction?

Cleaning out a brewing kit might get rid of the physical debris that accumulates in the interior, but it won’t get rid of contaminants that can cause off flavors or even illness.

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.”

#2 One Step No-Rinse Cleanser

#3 Clorox Bleach

Clorox Bleach homebrew best sanitizersClorox 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.

  • A strong sanitizing solution – no residues will be left


  • Requires thorough rinsing – due to its strong solution
