Sealed. New. Eco Soak Liquid Spa & Pool Filter Cartridge Cleaner (often branded as ecoTUB Filter Soak) is a concentrated liquid cleaning solution designed to deep-clean pleated filter cartridges for hot tubs, spas, and pools.
It is primarily used to remove built-up contaminants that regular rinsing cannot get rid of, such as body oils, lotions, grease, grime, and scale.
Key Uses & Benefits Deep Cleaning: Unlike a quick spray-down, this product is meant for a "soak" to break down embedded organic materials and minerals in the filter fabric.
Extending Filter Life: Regular deep cleaning (typically every month or with every water change) helps the filter last longer and operate more efficiently.
Eco-Friendly: It typically uses a coconut-based or enzyme-based formula that is non-foaming and biodegradable. The "spent" solution is often safe to pour on lawns or shrubs, unlike harsh chemical cleaners.
How to Use It Prepare the Solution: Mix the liquid with water in a large plastic bucket. A common ratio for this specific concentrate is 1 cup of cleaner to 5 gallons of water, but always check the bottle's specific instructions.
Soak: Submerge your dirty filter cartridge in the solution.
Wait: Let it soak, usually overnight or for 24 hours, to allow the enzymes to dissolve the buildup.
Rinse: Remove the filter and rinse it thoroughly with a hose to wash away the loosened debris and cleaning solution.
Dry: For best results, allow the filter to air dry before placing it back in the spa or pool.
This product is ideal for the deep "maintenance" cleanings required to keep your water clear, rather than the quick weekly rinse.
