Chemsan (250ml) — Acid Sanitiser
A self-foaming, no-rinse sanitiser for brewing equipment — fermenters, kegs, tanks, bottles, etc. It's a blend of phosphoric acid, benzenesulfonic acid, and isopropanol.
Key advantages: works even in the presence of organic soils, self-foams on contact, and requires no rinsing at the prescribed dilution (0.2% / 10ml per 5L water).
Essentially the UK equivalent of the popular US product StarSan.
