Answer: remove stains with black soap and waterproof your floor

Hello Patrick, slate is a magnificent porous natural stone that it is preferable to protect from the laying to avoid rising. To waterproof it, apply an oil-repellent product that you will find in a large DIY area. If white spots appear on your slate floor, it may be limestone, or simply mineral salts rising. It is enough, then, to rub the stain deeply with a touch of black soap diluted in water or soap with linseed oil mixed with a lot of water. For regular cleaning of your floor, add a glass of white vinegar to your rinse water. You too, send us your decoration question
