Instant Cartridge Clean is blue when applied to the filter. This color indicator shows where product has been applied and ensures you have complete coverage. It will remain blue until rinsed off and will not dye filter media.
Use Instant Cartridge Clean monthly or more often between deep cleanings with Leisure Time Filter Clean.
Remove cartridge filter element from filter housing and rinse thoroughly with water to remove loose debris. Saturate the filter element with water. Spray Leisure Time Instant Cartridge Clean over the entire surface for maximum effect. After 5 minutes, rinse filter completely with water and replace it back into the spa. Note: If the filter is not completely rinsed, foaming may occur. Use Leisure Time Foam Down if that occurs.
