High quality timber floors are a valuable investment, and as such, should be well maintained to protect your valuable asset. The greatest enemy of any floor covering is dust and grit.
Recommended regular maintenance procedures are: vacuum, or sweep with an anti-static mop daily and immediately wipe up any spillage.
If your floors have heavy usage, you will notice that some residue build up is visible on the surface and the polishing layer starts to wear. Standard mopping will not be enough to clean the surface and bring it back to a clean and protected condition.
