Every home we owned is was always something… pink rings, yellow rings or black mold growing. Always adding chemicals and scrubbing. So far it’s been three weeks and all looks crystal clear!
It seems to work but at times there is a grayish color just below the waterline I’ve gone and bought a plummet stone with a handle to scrub the bowels and still seam to get that gray color back it comes right off when you use toilet brush
I’m very happy with krazy clean. Simple
Easy and effective!
