Why should I run an acid cleaning cycle when the vessel looks perfectly clean?



Cleaners are great for removing the tough organic soil from the surface of stainless steel brewery tanks, but the additional acid cycle is required to remove inorganic material that could be hiding in the pores of your stainless steel that standard cleaners are too large to penetrate. Also, most cleaners are very sticky and, even after a good hot water rinse, there can still be residue inside. The acid cycle will remove the inorganic solids, beer stone, hard water, minerals and residue left over from the initial cleaning cycle.

The addition of an acid cycle also, when using an approved inorganic blend, adds a protective Passivation layer to your stainless steels surface of fermenter. This additional step can add extra life to your brewery tanks. How often? Every time ideally, but if cost is a issue every third cleaning cycle.

Passivation – the removal of free iron particles or iron compounds from the stainless steel surface of your brewery tanks by means of a chemical dissolution, most typically by a treatment with an acid solution.)
