MAINTENANCE AND CLEANING:
Never use acid- or alkaline-based detergents, such as Ajax, Cillit Bang, etc., as these can damage the surfaces of the tile. For regular cleaning, use a natural pH-neutral soap, such as Probat Klinkesæbe. If the tiles have been waxed, add approximately 2 cl of wax to the soap water every second wash.
NOTE: Lime residues and tougher stains can be removed with “Borup Kemi Rengøring til Marmor og Terrazzo”. For tougher stains, you may wet-sand the spot with 400 grit sandpaper. Clean the tile immediately after with clean water and let them dry. Re-wax the spot with two layers of wax after the stain has been removed.
