Today, the brewery equipment tanks made of carbon steel or with other protection layers has gradually become obsolete. And replaced by the stainless steel tanks, including brewhouse and beer fermenters etc. So two points should be noted when we choose the cleaning agents:
1. The nature of the organic contaminants
2. The nature of the equipment material that will be cleaned..
Firstly, the influence of acid to the stainless steel brewery equipment
The corrosion resistance of stainless steel has some limitations. Generally the austenitic stainless steel has good corrosion resistance on organic acids such as nitric acid and phosphoric acid. But it cannot be hydrochloric acid and vitriol !
Secondly, the influence of chloride to the stainless steel brewery equipment
The chloride has a certain effect(corrosion) on stainless steel materials, mostly are pitting corrosion, such as the small holes near the welding line. Generally there will be a strong but thin layer on the tank surface after passvition. But the chloride ion is really its enemy..
