Due to their porous nature, all of these stone types can stain. Granite slabs that are light in colour with a fine grain are more prone to staining, so it is best to clean off stain-prone substances as soon as possible. Should your marble, granite or onyx countertop get stained, follow this procedure:
- Create a paste with plaster of Paris and Jik®
- (Fabricators: plaster of Paris can be replaced with aluminium powder.)
- Cover and seal the area with plastic such as Gladwrap®
- Leave the covered paste for 24 hours, then remove.
