We’re on a well with hard, sulfurous water. Despite our filtering and purifying systems, the toilets still needed regular cleaning. Well, until we installed Krazy Kleen. Been a couple weeks and, after 1 final scrubbing of both the tank and bowl, everything is wonderfully sparkling clean. Crazy!
I am happy with the change in my bowl chemistry
Krazy Klean Pro works as advertised -- no toilet bowl ring or film without damage to tank hardware.
