What are the differences between the various cleaners?
"Each cleaner is a proprietary blend of various components including emulsifiers, surfactants and other agents designed to make your water wetter (better for the breaking down of oils and soils) and lift them off of and unable to resettle on equipment surfaces. Brewers tend to develop an affection for one cleaner over time and it usually is a matter of personal preference.
PBW – PBW stands for Powdered Brewery Wash. This product is widely used in commercial breweries, Brew Pubs and Micro Breweries across the country. Use 1–2 ounces per gallon for cleaning boil kettles, 3/4 of an ounce per gallon for fermenters, kegs and other brewing equipment. Soaking overnight will easily remove stubborn, caked on organic deposits without scrubbing. PBW is environmentally friendly, biodegradeable, and will not harm septic systems and was one of the earliest products originally developed for a large Rocky Mountain brewer who wanted an alkali cleaner which would outperform an acid while not dissolving the copper from their kettles.
STRAIGHT-A – Cleans with oxygen & does not contain any chlorine, bisulphites, organic compounds or phosphates. Superior wetting power helps water penetrate & lift soils off surfaces. Removes labels with minimum soak time. Higher alkalinity dissolves & neutralizes acidic soils. Environmentally sound & biodegradable. Use 1 tablespoon per gallon of water. Straight-A solution will retain quite a bit of its effectiveness over a long period of time (although a fresh solution will also perform the best).
B-BRITE – This product is excellent for removing stubborn fermentation residues and organic deposits. Also great for removing labels from beer bottles. Use 1 tablespoon per gallon of water.
SANICLEAN - Saniclean is a final rinse, happens to be acid-based and is non-foaming. As microorganisms cannot thrive in an acid environment, this cleaner is a very popular final rinse in commercial breweries who do not like the foam from such products as Star San. The dosage is 2 oz. for 5 gallons and a contact time of 2 to 3 minutes is required.
ONE-STEP – This environmentally friendly product contains no chlorine, which can leave a film on glassware and corrode stainless steel. Not having Chlorine is especially appealing to Vintners. Requires two minutes of contact time, and no rinsing is necessary. Use 1 tablespoon per gallon of water. One time use when used as a final rinse. Works well on plastic and metals. In a closed, clean container in a refrigerator, the solution is good for over a month (but let it warm up before you use it)."
