Features: This spray-on cleaner is touted to be safe for fiberglass, and we’d have to agree, having used it for years without problems. Its acidic base foams on contact with a soiled surface, indicating a reaction is taking place to remove stains.
Instructions: Apply directly to the nonskid surface, let stand and rinse.
Performance Report: It too bowed to Soft Scrub on the full-monty test and “set” the wine stain. It substantially removed the cola stain and the blood and guts.
