For nonbackwashable D.E. or cartridge filters:

  1. Turn pump off and rinse off loose dirt from filter elements.
  2. Apply product by spraying directly onto the elements. If needed, lightly brush heavy grease spots.
  3. Let wet filter elements sit for 5 – 10 minutes. For heavily soiled filters, allow elements to sit for one hour.
  4. Rinse elements thoroughly with full-strength water from a garden hose.
  5. Reassemble filter and resume normal operation.

Note: As an alternative, soak filter elements overnight in a solution of 32 oz. of this product added to 5 gallons of water. Rinse elements thoroughly with water from a garden hose.

Sand filters and some D.E. filters:

  1. Backwash filter thoroughly, then turn off the pump. Chlorine must be removed from the skimmer basket prior to applying this product. Turn off the automatic feeder, if present.
  2. Pour entire bottle of Kleen-It into skimmer.
  3. Turn pump on until it primes and Kleen-It moves into the filter.
  4. Leave the filter selector in the backwash or closed position.
  5. Wait one hour. Turn pump on with selector in backwash position and backwash until the waste water is clear.
  6. Return to normal operation.
