I have been using KOH for over two years, it’s just perfect. Cleans everything without the damage to environment and my lungs lol this is brilliant on tea cups and works better than bleach. It’s great on mirrors and bathrooms. I haven’t found anything it isn’t great on. Highly recommend. I have the mop as well but find in goes through the liquid too quickly using the mop. It works just as well lightly spraying the floor from the bottle and wiping it or using the mop head. It’s so nice to not be chocking on the cleaning products you can even add essential oils if you want the smell but I am happy without it as it left a smell in the bottle.
