PBW--Powdered Brewery Wash 1 lb (a trademarked product of the Five Star Chemical Company)
PBW is an alkaline, non-caustic, environmentally friendly cleaner capable of removing protein soils and stubborn stains at a wide temperature range. It is hard water usable, easy rinsing and has multiple uses.
For the purposes of cleaning stainless steel micron filters, Arbor Fabricating recommends the following procedures:
Always clean filter in between usages!!! Failing to do so will result in filter residue drying in place and leading to a less effective filtration.
First, remove filtered residue as best as possible using high pressured water. The concentration of PBW depends on the soil load to be cleaned. Removing soil ahead of time loosens proteins and other elements that might otherwise dry onto the filter.
Always add PBW or any cleaning or sanitizing product to the measured amount of water. Use 1-2 oz. (1 gently rounded teaspoon is about 1 oz) per gallon of water (.075% solution by weight) for 25-35 minutes, at temperatures between 100-160 degrees Fahrenheit. Rinse with potable water immediately after at same temperature as the wash temperature. The rinsing off of PBW is completed when the filter is no longer slippery
