Five Star Acid Cleaner #5, 1 Gallon

Removes organic materials with inorganic materials. Nitric Acid nitrates the amino acids, as well as dissolving minerals, which then allows it to remove lay­ers of soil and not be stopped by ‘bio-layering’ which can occur when multiple brews are done without performing a cleaning regimen between each brew. A layering of soil types can also be a problem in direct fire kettles. Is the most aggressive stone removing acid readily available to brewers Reacts directly with the non-ferrous elements of stainless steel to actively cause the metal to passivate (or re-passivate). Other acids, by themselves, can clean the stainless steel of soils &/or rust to the point that the stainless steel can ‘heal’ itself, however, that process can require several days. By contrast, using a Nitric cleaning process, known as ‘pickling’ the stainless, is more effective and can be done in a single CIP session and subsequent air-drying.
