Before you decide to clean your cork floors with any commercial cleaner, check your warranty. If you treat the floors with a solution you’re not supposed to, you can void your warranty, leaving you completely responsible for any damage or replacement costs. For example, most cork flooring manufacturers specifically mention that you should stay away from Murphy’s Oil Soap solution.   Although this cleaner is formulated for wood, cork is a gentle flooring type that’s susceptible to stains and damage. So if you ever want to use a commercial solution, find one that’s specifically made for cork floors.
