Five Star Liquid PBW – 32 oz Cleaner for Brewing and Fermentation

This liquid version of PBW gives you the same cleaning power as the powder but skips the extra step of dissolving it. It mixes easily into water, even when it’s not hot, so you can get your cleaning started faster without worrying about clumps.

The 32 oz bottle is good for regular use in home fermentation, including homebrewing in both large- and small-batch fermentation setups. It’s designed to remove the common buildup you see after fermentation—like krausen, proteins, sugars, and hop oils. You can use it to clean kegs, carboys, tubing, valves, and other brewing parts.

The formula is buffered and non-caustic, so it won’t damage metal, rubber, or plastic gear. To use it, just add 1 to 2 oz of cleaner per gallon of water. Soak your gear for 15 to 30 minutes, or longer if it’s heavily soiled. You can also run it through pumps or lines for CIP cleaning. After cleaning, rinse well, then sanitize as usual before reuse.

This size is a solid choice for anyone doing regular cleanups or maintaining a small fermentation system.
