This product will clean the spa filter.
DIRECTIONS FOR USE:
Remove Filter. Remove any loose material with water (pressure rinsing is best). Spray all over with Instant Filter Cleaner paying particular attention to the filters flukes and veins. Allow to dwell for about 15 minutes before rinsing away with clean water to remove all foam residues. Heavily soiled filters may require a second application. Once cleaned the filter can be returned to the filter compartment of the pool/ hot tub.
