Hot Tub Things™ Instant Cartridge Cleaner - Spray-On Filter Cleaner (32 fl oz)

Rinse the cartridge filter thoroughly to remove loose debris.

While the filter is still wet, spray Instant Cartridge Cleaner evenly over the surface until all pleats are coated.

Allow the cleaner to dwell for about five minutes.

Rinse thoroughly with a hose until all residue and loosened debris are gone.

Reinstall the cartridge filter and restore spa operation.

Repeat as needed or every few weeks for best results.

Q: How long should I leave the spray on the filter?

A: Wait about five minutes before rinsing to allow the cleaner to dissolve oils and grease effectively.

Q: Is it safe for use with chlorine or bromine systems?

A: Yes — Hot Tub Things™ Instant Cartridge Cleaner is compatible with chlorine, bromine and ozone spa systems.

Q: Why use a dedicated filter cleaner instead of just hosing it off?

A: Hosing removes visible debris but not embedded oils and lotions that clog pleats. A degreasing cleaner restores proper flow and extends filter life.
