Instructions:

• Remove the filter from spa and rinse with a spray hose.
• Add two capfuls of Spa Marvel Filter Cleaner to up to 20 litres (5 gallons) of fresh water in a pail and mix to dissolve.
• Soak the filter overnight in the solution.
• After soaking the filter in the hot tub filter cleaner it is critical that the debris is thoroughly removed from the pleats of the filters. The water pressure from showers and kitchen sinks is often not strong enough to remove the debris. If after rinsing your filters there is still discolouration in the pleats of the filters or if they still smell, then they are not clean. Many people use a pressure washer (gently and carefully) to quickly and effectively remove the debris after soaking the filter. If you do not have access to a pressure washer, the sprayer at the coin-operated car wash works well.  Most reusable hot tub filters ought to be replaced after 6 months of use.
