Does urineFREE remove black stains caused by urine on timber floor boards?

urine stain on floorboards

The black stains on the wood floors are usually urine accumulation. As you treat these stains with urineFREE the black will start to turn grey and progressively lighten. Any wood damage from the uric acid will be irreversible so you may end up with a patch of light grey on your floor.

During treatment, often these stains will become darker and the odour greater on the first application. This is common. Repeated applications will see the colour become lighter and the odour vanish. After you are satisfied you have eliminated all the urine, if the floor is to be exposed or if you are unhappy with the colour then sand back the floor to its original state, revarnish and seal.
