A product called "one step". Developed by a chemist specifically for brewers
for sanitising beer or wine Equipments. Available from local Brew shops..
Will leave no stains because unlike other cleaners it uses oxygen bubbles. I
have used it and liked it. Sometimes I used Ajax bleach too. But I make sure
I rinsed it and dried it. I don't see any problems.
