PBW, Powdered Brewery Wash, by Five Star Chemicals
PBW is an alkaline detergent that more than an effective substitute for caustic soda cleaners. Its unique formulation of buffers and mild alkalis makes it safe on skin. It is also safe on soft metals such as stainless steel, aluminum, and on plastics. PBW uses active oxygen to penetrate carbon or protein soils and is not effected by hard water. PBW has been formulated as a C.I.P. cleaner and is very effective in removing protein soils found on brew kettles, fermenters, conditioning tanks, filters and all packaging areas. The concentrations to remove these soils are typically in the 1% range. PBW is an excellent choice as a soak cleaner because it does not require excessive heat as do most caustic based cleaners. This product has cleaned brass and copper filters, and industrial aluminum surfaces successfully.
Drew started using PBW almost 15 years ago and has never turned back. Mix up between 3/4 and 2 oz per gallon depending on the strength you need. Mix the solution right up in your fermenter or brew kettle and let it sit overnight. This amazing cleaner will dissolve the biological build ups on your equipment requiring virtually no scrubbing. As a matter of fact, Drew will tell you that when he is soaking his kettle he’ll often put a pot or pan that has baked on grime he can’t get off.
PBW is meant to be a cleaner so don’t forget to sanitize afterwards. For more detailed info about PBW check out this link directly to the 5 Star PBW pdf.
Five Star Chemical’s Rules for cleaning and sanitization
1. You can only sanitize clean equipment.
2. Dirty equipment will always contain bacteria.
3. Cleaners ARE NOT sanitizers. Whether alkali or acid, cleaners should not be used as the final procedure.
4. Sanitizers ARE NOT cleaners. Sanitizing is the final procedure after cleaning or on clean equipment just prior to brewing.
5. Cleaning and sanitizing can be improved by time and temperature. Allowing longer contact time and/or increasing the temperature of solutions will improve the results.
6. Do not overuse chemicals. “More is not better”. It normally requires more water and/or higher temperatures to rinse, and may leave an unwanted residue or just cake on to the equipment.
7. Follow the directions of any chemical you use.
8. Cleaners and sanitizers must come in contact with 100% of the soils. This means that all blind areas, such as man-way lips or racking arms, must be hand cleaned and sanitized. Use of spray balls can be very effective.
9. Never add water to chemicals. Always blend PBW into water.
