“Probably the only Koh product I am not impressed with. Didn't do much really and left me still scrubbing. With a gel/liquid it at least breaks down the skids up higher on the bowl. Didn't remove the black buildup in the far corners at the bottom. Unfortunately, I won't be buying these again. UPDATE- Koh have fully refunded my purchase. Honest company and I am extremely happy with my other repeated purchases.”
