Alcohol, ammoniac or bleach products have a bleaching effect on waxed surfaces.
If any of these substances have dripped onto your wax finished natural stone floor, forming white stains, use PS87 to dewax the entire surface. Rinse thoroughly with water.
When the surface is dry and clean, apply a new wax treatment: MATT* for a natural effect, SATIN* for a satin finish, and CLASSIC* or LONGLIFE* for a gloss finish.
