The Premium RV Black Streak & Bug Remover from Thetford effectively removes black streaks, sun-baked bugs, and other tough soils.
Created specifically for RVs, boats, cars, trucks, vans, snowmobiles, ATVs, and other vehicles, the formula is safe on gel coats, RVs, fiberglass, decals, and painted aluminum.
You won't have to worry about damaging the seals around windows, and it is 100% biodegradable and non-flammable.
As this is an aggressive cleaner that uses alkaline detergents, it is best to spot test all surfaces, particularly on old or weathered vehicles.
Ensure the surface is clean before applying the product with a clean cloth or sponge, and rinse with water immediately after.
For optimal results, use the product in shade.
