Stain removal: remove mold stains, grease and black spots

Stain removal in RVs, campers and boats often boils down to the same things: textiles that get spots from moisture, kitchen and seating grease stains, and tough grime that sticks to tile, plastic and wood. Biocool Spray Away Stains was developed to remove mold discoloration and tough stains, break down grime, grease and black spots, and be used as step two after mold treatment when you want to get the surface completely clean again.

Tips

Act quickly. Stains that have dried in become harder to remove.
Always test on a small hidden area first, especially on colored textiles.
Blot and dry up. Do not scrub hard. This reduces the risk of ring stains.
Let the product do the work. Contact time is often more important than hard scrubbing.
Rinse thoroughly afterwards and let the surface dry completely.
For moisture and black spots: distinguish between treating active mold and removing discoloration.

Step-by-step: stain removal on textiles and sensitive surfaces

Identify the surface and prepare
Blot up liquid with paper towels if the stain is fresh. Brush away loose grime if it is dry. On textiles: blot gently.
Test on a hidden surface
Spray a little and check that the material can tolerate the treatment before proceeding.
Spray directly onto the stain
Cover the stain evenly.
Let it sit
Let the product work for five to ten minutes.
Treat lightly if needed
Scrub gently with a brush or sponge if the stain is stubborn.
Rinse thoroughly with water
Rinse until the surface feels clean. On textiles that cannot be rinsed heavily: wipe off with a clean damp cloth in multiple passes.
Let dry completely
Ventilate. Remaining moisture makes it easier for stains and spots to return.
Repeat as needed
Repeat the treatment if the stain does not come off the first time.

Common stains in RVs, campers and boats

Mold stains and black spots
If you suspect active mold: treat it first. Once the infestation has been treated, you can remove any remaining stains and discoloration.

Grease and food stains
Blot up excess immediately. Spray, let it sit, rinse or wipe off thoroughly. It’s better to repeat the process than scrub hard.

Soot and tough grime
Work in passes. It is often more effective to do two gentle treatments than one aggressive one that risks damaging the surface.

Materials that often work well

The product was developed to be gentle on materials and can be used on tile, wood, plastic and textiles. Always test on sensitive and colored materials first.
