I was introduced to Koh from my daughter who recently moved into her own home. All her friends recommended. Absolutely love it, we have dark porcelain floor tiles and have tried every product that is on the market and that includes steam mops etc and they are always left cloudy/smeary. But the Koh cleaner / mop is amazing, wish I knew about it a long time ago. So easy and just love it. The best thing ever. It’s awesome for bathrooms/kitchen cupboards etc. We have black granite benches in the kitchen and I have always used Windex with paper towel. I tried to Koh cleaner and the polish BUT definitely not good on granite. Left like a film/cloudy residue on them. Went back to the Windex and they are nearly back to normal, took a while to get rid of the film it left on them. So overall I am truly happy and will not use any other cleaning product throughout the whole house (except the granite benches) that’s a real no no
