Comparing Caustic Cleaners for Home Brewing: B-Brite, One Step, and PBW
When brewing at beer home, proper cleanliness and sanitization is crucial to producing the best tasting beer. Before we can effectively sanitize our equipment, we must make sure it is clean. There are many cleaning products on the market, but in this article we will focus on three of the most popular brands available for home brewers: B-Brite, One Step, and PBW (Powdered Brewery Wash). Let’s take a look at these cleaning agents to understand which is the best to use based upon your situation.
B-Brite & One Step: Non-Caustic and Easy-to-Use
B-Brite and One Step are very similar in terms of their properties and use, so we’ll discuss them together. Both are non-caustic cleaners, making them user-friendly and safe for most surfaces used in home brewing.
Key Features:
- Non-Caustic: B-Brite and One Step are safe for materials like stainless steel, glass, and plastic. Unlike stronger, caustic cleaners, they don’t require gloves or special handling.
- Oxygen-Based: These cleaners rely on oxygen via sodium percarbonate to break down organic materials, which makes them effective for removing grime and stains.
- No Rinse (for some applications): In low concentrations, they can be used without a rinse step, saving time. However, many brewers prefer to rinse thoroughly to avoid any residue that could affect your beer's taste.
- Environmentally Friendly: Both products are biodegradable, making them a greener option for eco-conscious brewers.
- Low Cost: B-Brite and One Step are inexpensive, which leaves you with more money to purchase brewing ingredients!
Ideal Use:
- Cleaning fermenters, bottles, tubing, and general brewing equipment.
- Great for light cleaning tasks where heavy-duty grime isn’t present.
- Suitable for smaller homebrew setups where convenience is key.
PBW (Powdered Brewery Wash): The Heavy-Duty Cleaner
PBW, on the other hand, is a stronger, caustic-based cleaner formulated specifically for the tough cleaning tasks. PBW was originally developed for commercial breweries, but PBW has become the go-to cleaner for homebrewers who need something more powerful.
Key Features:
-
Caustic Formula: PBW contains sodium metasilicate and other ingredients that break down tough organic deposits, especially dried-on grime, proteins, and hop residues. PBW is not as caustic as sodium hydroxide (lye), but the sodium metasilicate is alkaline enough to effectively clean without the extreme hazards of more caustic substances.
-
Versatile: PBW works well in both soft and hard water conditions, making it suitable for almost any brewing environment.
- Safe for Equipment: Unlike B-Brite or One Step, gloves are recommended when using PBW. Although PBW is powerful, it's safe for use on stainless steel, glass, and plastic when used at recommended concentrations. PBW can also be used on copper and brass, but with some caution: prolonged exposure or high concentrations on copper or brass can cause discoloration or damage. Thus, for copper and brass, use the proper concentration, avoid extended soaking times and immediately rinse thoroughly.
- Heat-Activated: PBW works best in warm to hot water, which increases its effectiveness in removing stubborn deposits. Of course, regular precautions apply. Never add warm or hot water to glass carboys, because the sudden thermal shock can cause the carboys to break.
- More Expensive: PBW does cost more than both B-Brite and One Step, but a lot of home brewers say it's worth it. You can use PBW in every situation, so some home brewers prefer the simplicity of just using one type of cleaner.
Ideal Use:
- Ideal for cleaning brew kettles, mash tuns, and equipment with heavy organic residues. Many home brewers with large stainless fermenters use CIP (clean-in-place) spray balls, so they do not have to completely fill their vessels with solution for cleaning.
- Excellent for deep cleaning or when you’ve let equipment sit dirty for too long.
- Preferred by homebrewers with larger setups or those who brew frequently and need heavy-duty cleaning power.
- Great for other household tasks, like cleaning stainless steel thermoses and water bottles.

Conclusion
Choosing between B-Brite, One Step, and PBW depends on your cleaning situation. If you’re looking for an inexpensive, mild, easy-to-use cleaner for everyday cleaning tasks, B-Brite and One Step are great options. However, if you need a more powerful cleaner for larger brewing equipment or stubborn grime, PBW is better.
Proper cleaning requires the proper compounds, and each of these cleaners are good to have in your home brewer’s toolkit. This way you're always prepared for every situation, whether you’re bottling your latest batch or deep cleaning your brew kettle.
