You're washing your vinyl siding, and everything is going well. That is, until you find an oil-based stain on the side near the garage. Soap and water won't remove it, and you have no clue what to use to get the oil off without damaging the vinyl siding. You'll be relieved to learn that there's a way to remove the stain.
Things You'll Need
Orange-based citrus cleaner
Garden hose or pressure washer
Spray the oil-based stain liberally with full-strength, orange-based citrus cleaner, until the entire stain area is wet.
Soak the stain for 20 minutes, reapplying the cleaner if it begins to dry.
Brush the stain gently with a wet, soft-bristled brush, using a circular motion and adding water, if the area is too dry for the brush to move smoothly.
Rinse the cleaner off, using a hose or pressure washer to remove all residue. The oil-based stains will be gone from your vinyl siding.
Wash the rest of the wall so you don’t have one spot that is brightly clean.
