Over time you find a thin layer of yellowish material building up on the sides of your fermenter which is difficult to wash off. Using abrasive cleaners such as Stainless Steel wool is not recommended as it scratches the surface and remove passivation.
Use at the rate of 8ml per litre of water or 1oz per US Gallon.
