It’s not easy to find a product to clean unvarnished timber floors. After 17 years my floors have dulled. I finally bit the bullet and bought the KOH cleaning package not really expecting anything great but how wrong I was. After just one run around with the KOH all purpose cleaner and I have my shine back. Obviously after years of wear there are dull patches but even these looked brighter. Why did I wait so long. As far as the kitchen cleaner goes I cooked pork belly, sprayed the baking tray and waited 15 minutes before brushing it clean. Another great KOH product.
