Things You'll Need:
- Mold-off, a spray cleaner designed for boat upholstery
- Thick clean cloths
-
Step 1
Spray on Mold-off, or similar non-bleach boat upholstery cleaner, on all moldy or mildewed areas. Make sure to spray in upholstery creases and seams where mildew can get a strong hold. Use enough product to cover the entire area, beyond the visible stain. Some mold spores may have traveled but aren't showing yet.
-
Step 2
Leave the spray on over night or longer, if using Mold-Off. This allows it ample time for the ingredients to kill mildew.
-
Step 3
Wipe down the areas with a dry cloth. If some mildew stains are still present, rub with a damp cloth.
-
Step 4
Spray the cleaner on other boat surfaces, such as carpeting to eliminate mildew spores in those areas. This will help prevent those spores from re-infesting the upholstery.
