Bio-Kleen Fiberglass Cleaner | 1 Gallon, Lemon Scent

Hard water and road grime take a toll on fiberglass RV exteriors, leaving behind rust streaks, scale, lime deposits, and yellow staining that regular soap won't touch. Bio-Kleen Fiberglass Cleaner is formulated to penetrate that mineral buildup fast and dissolve it, so you can rinse away corrosion and soap scum without heavy scrubbing.

• Dissolves rust, scale, lime, and mineral deposits on contact
• Removes soap scum, chalking, and yellow water stains from fiberglass
• Safe for use on metals, tile, grout, and other acid-resistant surfaces
• Biodegradable, lemon-scented formula
• Full 1-gallon (128 fl oz) bottle

Beyond the RV exterior, it also works on boat hulls and pontoons, wheels and rims, sinks, tubs, shower stalls, and ceramic tile and grout - one bottle covers a lot of cleaning jobs around the rig and campsite.
