Description

FreshWater Filter Cleaner

Overview

FreshWater Filter Cleaner is a 2.7 lb granular concentrate formulated to deep-clean hot tub filter cartridges through an overnight soak — restoring filters that monthly spray-cleaning alone can't fully refresh. Mix one pound of granules per 5 gallons of warm water in a bucket, soak the filter for 10–12 hours, then rinse thoroughly and reinstall. The deep-soak chemistry penetrates pleats and dissolves the layered buildup of body oils, lotion residue, calcium scale, and organic film that accumulates over months of use.

This is the quarterly deep clean — not the monthly maintenance clean. If you're cleaning your filter monthly with FreshWater Instant Filter Cleaner (the spray-and-rinse version), this product is the second tier in your filter care routine — the every-3-months reset that handles deep buildup the spray can't reach. Most owners need both products on hand, used at different intervals.

The Three-Tier Filter Cleaning Schedule

Hot tub filters need three different cleaning approaches, used at three different intervals. Each handles a different type of buildup:

Tier Method Time What It Removes
1. Weekly Hose rinse 2 minutes Surface debris (hair, leaves, large particles)
2. Monthly Spray cleaner (Instant Filter Cleaner) 5 minutes Body oils, lotion residue, light scale
3. Quarterly Deep soak (this product) 10–12 hours Heavy organic buildup, deep scale, lotion saturation

What’s in the Box

  • 1 × FreshWater Filter Cleaner — 2.7 lb container of granular cleaner
  • Dosing instructions on the label

Key Features

  • 2.7 lb granular concentrate — makes approximately 13.5 gallons of cleaning solution per container
  • 10–12 hour overnight soak dissolves deep buildup that spray cleaners can't reach
  • Restores filter performance on filters that look "done" — often back to near-new clean
  • Extends cartridge replacement intervals — well-maintained filters last 12+ months instead of 6
  • Compatible with all sanitizer systems — chlorine, bromine, ozone, biguanide, FreshWater Salt, ACE Salt
  • Safe for all standard hot tub filter cartridges — Hot Spring, Caldera, Sundance, Bullfrog, Jacuzzi, and others
  • OEM Watkins Wellness formula — manufactured to the same purity standards as the rest of the FreshWater line

Directions

  1. Power off the spa at the breakers before removing the filter cartridge.
  2. Remove the cartridge from the filter compartment per your owner's manual.
  3. Rinse the filter with a garden hose to remove loose debris from the pleats. (A filter cleaning wand makes this faster if you have one.)
  4. Fill a clean plastic bucket with warm water — enough to fully submerge the filter cartridge.
  5. Add the cleaner at a ratio of 1 pound of granules per 5 gallons of water. For a typical 4-gallon bucket, that's about 13 oz (just under a pound).
  6. Stir to dissolve the granules completely before adding the filter.
  7. Submerge the filter fully in the solution. Make sure all pleats are covered.
  8. Soak for 10–12 hours. Overnight is the typical approach — start in the evening, finish in the morning.
  9. Remove the filter and rinse thoroughly with a high-pressure nozzle, working between each pleat until water runs completely clear.
  10. Let the filter dry if possible (24 hours air-drying gives chemicals time to fully off-gas) before reinstalling.
  11. Reinstall the cartridge, restore power, and run the filter cycle.
  12. For heavily soiled filters, repeat steps 1–10 with a fresh batch of cleaning solution.

    Pro tip: keep two filter cartridges and rotate them: A single 2.7 lb container of deep cleaner makes enough solution for 3–4 deep cleans. If you keep two cartridges and rotate them (one in the spa, one drying after a clean), you can do a deep soak of the off-cartridge without your spa being out of service. The rotating-cartridge approach also nearly doubles the effective lifespan of each cartridge.
