Ultramar Power Cleaner is a super-strong fabric cleaner. Always use it as Step 2. For when nothing else works.
- Apply Ultramar Power Cleaner to the fabric with a plant spray, spray, or brush.
- Then rub in with a strong soft brush
- Allow to soak in for approximately 1 hour.
- Can't see any change?
- Spray a little extra Power Cleaner and brush in again.
- Again allow to soak in.
- Repeat this until the stains are gone. This can sometimes take a few hours.
- Then rinse well with a brush and plenty of water.
- Test Power Cleaner on a small, unobtrusive piece.
- Use Ultramar Sprayhood & Tent Protector or Canvas & Cotton Protector to make the fabric waterproof and protect it against mould, algae, stains.
