Pool Filter Degreaser - Sand & Cartridge Deep Clean

Concentrated pool filter degreaser for cartridge and DE filters. Soaks out body oil, sun cream and bound clarifier in 8-12 hours, restoring filter flow and extending cartridge life.

• Soaks oil, grease and clarifier residue out of cartridge filters.
• Restores filter flow rate and lowers running pressure.
• Extends cartridge life by 12-18 months on regular use.
• Compatible with all cartridge and DE filter materials.
• Replaces brushes and detergent cleaning routines.

Sizes and prices

• 5L: £22.00
• 10L: £40.25
• 25L: £95.00

When you need it

• Filter pressure stays high after backwashing.
• Cartridge looks discoloured even after rinse.
• Filter flow has dropped despite clean media.
• Annual deep clean of cartridge or DE elements.
• After heavy bather load left oil and sun cream load.

How to use

1. Remove cartridge from filter housing; rinse off loose debris.
2. Fill a clean bucket with 20 L of warm water.
3. Add 500 ml of degreaser to the bucket.
4. Submerge cartridge fully; cover and leave 8-12 hours.
5. Rinse cartridge thoroughly with clean water until run-off is clear.
6. Refit cartridge; expect immediate flow improvement.

Dosing guide

Per cartridge soak in 20 L bucket. Larger DE elements may need a 40 L tray and 1 L of degreaser.

• For Single C100 cartridge, add 500 ml in 20 L water to reach 8-12 hour soak.
• For Single C200 cartridge, add 750 ml in 20 L water to reach 8-12 hour soak.
• For Set of 4 small cartridges, add 1.5 L in 40 L tray to reach 8-12 hour soak.
• For DE element panel, add 1 L in 40 L tray to reach 8-12 hour soak.
• For Quarterly deep clean, add 500 ml per cartridge to reach Standard soak.

How it works

Alkaline surfactant blend based on potassium hydroxide (3-5% w/w) and sequestered surfactant package, designed for plastic-safe oil removal.

Potassium hydroxide saponifies body oils and sun cream into water-soluble soaps that rinse free; the surfactant package wets the cartridge pleats so the alkaline solution penetrates fully.

Cartridge filters look clean after a backwash but body oils stick in the pleats and choke flow. Without periodic degreasing, you replace cartridges every 12 months instead of every 24-36 months.

Frequently asked questions

How often do I degrease?

Quarterly for routine; monthly for high-use commercial pools.

How long do I soak?

8-12 hours; cartridge pleats take time to release oil. Do not exceed 24 hours.

Where do I rinse the cartridge?

Outside, into mains drain. Never rinse degreaser back into the pool.

Pack sizes?

1 L and 5 L drums.

Will it damage my cartridge?

No. Plastic-safe alkaline blend designed for cartridge media. Avoid soaking over 24 hours.

Will it work on sand filters?

Sand filters do not use cartridges; backwash with normal cycle and add Filter Cleaner Granules instead.

What is the active ingredient?

Potassium hydroxide 3-5% w/w with sequestered surfactant blend.

Why alkaline?

Body oils and sun cream are saponified by alkali; degreasing soap is the standard cartridge cleaning chemistry.

Does it remove calcium scale?

No. Use a pool tile cleaner or dilute acid soak after degreasing for full restoration.

Cartridge still slow?

Add an acid soak after degreaser; calcium scale needs different chemistry.

Pleats swollen?

Air-dry 24 hours; reduce soak time next round.

Filter degreaser vs filter cleaner granules?

Degreaser is for cartridge soaks; granules are for sand filter backwash. Different filter types, different chemistry.

Filter degreaser vs instant filter cleaner?

Degreaser is the deep soak; instant cleaner is a faster spray-and-rinse for cartridges. Use degreaser quarterly, instant for routine top-ups.
