It’s just amazing. What can’t it clean? I use it in the kitchen and bathroom. I use it in my other room for cleaning and polishing. It cleans wood, leather and glass. I even use it to clean my horse tack that is saddle, bridle and metal bits. Today a workmen had a problem with an oil spill on my neighbors driveway. I gave a good spray of KOH and the oil rinsed away. The two scaffolders both took screenshots of the product as they were so impressed they planned to buy some. I would be very rich if I had a pound for every connection who has ordered KOH because of me
