So far good. It has prevented the ring around the waterline. We shall see in couple of months.
We’ve been using Kraft Klean for about 3 weeks now and so far the toilet bowl in all 4 bathrooms are staying as clean as they were when we cleaned them prior to starting with Krazy Klein. Keep up the good work!
I just put it in my toilets and waited. However, they should have said clean any current rings before putting it in, because my ring didn’t go away. Then I cleaned the rings and since then, no more rings! So definitely start with a clean bowl!
It's been 2 weeks and so far everything is good! I love the 10 years warranty, we'll see how that goes!
