Description
Keep your spa and pool filtration performing at its best with the Darlly Spa/Pool Dual Action Filter Cleaner (32 oz) [P-DAFC]. This versatile cleaner is designed to tackle oil, grease, soap residues, minerals, and scale that clog filter cartridges, DE grids, and even sand filters. The result? clearer water, improved flow, and extended filter life without the frequent need to replace components.
Dual-action cleaning for all filter types
Whether you’re maintaining a cartridge filter, DE grid system, or a sand filter, this cleaner delivers a two-pronged approach:
- Direct spray application for quick surface cleaning and spot treatment
- Deep soaking capability to dissolve tough buildup and restore efficiency
The spray bottle design makes it easy to target dirty areas without disassembly, while the option to soak overnight ensures even stubborn grime is lifted away.
Why this cleaner stands out
- Broad compatibility: effective on cartridge filters, sand filters, and DE grids, making it a go‑to for full filter maintenance.
- Oil, grease, dirt, and soap removal: tackles the contaminants that slow filtration and dull water clarity.
- Convenient upkeep: use for routine quick cleans or longer soaks to maximize cleaning depth without replacement costs.
- Sanitizer-friendly: compatible with chlorine, bromine, and biguanide sanitizers, so you can clean without disrupting your sanitizer regimen.
How to use for best results
- Remove grids or cartridges from the filter.
- Place the cartridge or grids upright in the solution.
- Soak: a minimum of 3 hours; for maximum effectiveness, soak overnight.
- Rinse thoroughly with a hose or high‑pressure nozzle to remove loosened debris, then reinstall in the filter system.
Tip: While the filter is still wet after soaking, you can apply Instant Filter Cleaner to the total surface area and let it sit for 3–5 minutes for an extra clean. Rinse again and reinstall.
Maintenance cadence and expert tips
- Clean filters monthly or as needed to maintain optimal flow and water clarity.
- For periodic deep cleaning, consider a 24-hour soak with Phoenix Filter Cleaner a few times per year to refresh older cartridges.
- After cleaning, ensure all components are fully rinsed to remove any residue before returning them to service.

It’s especially valuable for systems using cartridges, DE grids, or sand filters, and for those who want a simple, reliable routine to support consistent sanitization with chlorine, bromine, or biguanide systems.
