Things You'll Need
Non-abrasive multipurpose cleaner
Acetone, turpentine or nail polish remover
Cultured marble is commonly used for bathroom sinks and kitchen countertops because of its attractive appearance and durability. If you accidentally spill hair dye on a marble surface, or if dye transfers to the surface from your hands or hair, you can easily clean it up with a common household cleanser or solvent. Unlike regular marble, cultured marble surfaces are non-porous and won't absorb anything you spill.
Wipe up as much dye as possible, using a damp paper towel.
Cover the stained area with a non-abrasive cleanser and wipe it off with a soft cloth.
Rinse off the area and repeat the cleaning and rinsing pattern until the hair dye stain is completely removed. If cleaning the stain with an all-purpose cleaner proves ineffective, you will need to use a solvent.
Apply a small amount of turpentine, acetone or nail polish remover to a soft cloth and wipe the stain. Rinse the spot with water and repeat the pattern until the stain is removed.
