Spa Depot Power Soak Hot Tub & Pool Filter Cartridge Cleaner - 2 x 1 lb. bottles

I had clean but foamy water in the spa. Tried different things, but nothing helped with he foam. I thought I had to change the water sooner, but decided ti try this product first. And it worked. A bit pricy, but really works!

Cleans, cleans , cleans. I soak the filter for about 45 mins, steeping like a tea bag for most of the time, rinse well with pressure and you get a bright white filter. Pics taken after about 40 mins of soaking and moving the filter.

However gross it may sound, people's body oils and sunscreen residue won't come out of a thickly pleated cartridge filter (not the single pleated, I mean the $120 ones) just from rinsing. At the end of every pool season I will thoroughly rinse off the filter, I take a cup of this powder, mix it with HOT WATER and place it into it's filter housing (with the valves closed obviously) and let it soak in there for the entire time I am closing up the pool. At the end of the day (about 5hrs) I take the filter out and drain the filter housing of the oh-so-smelly water that was extracted from the filter then rinse everything thoroughly again. No, it will not be white like it's brand new (it never will), but I've removed all the oils and yuckies that would cause cloudy water and the filter is ready for next summer. This stuff is great!

It worked as indicated.👍

Product is a value with respect to price and performance. It is much lower priced than some other products, but the hazardous acid wash products (mix of Muriatic Acid and Perchloric Acid) work much better. The product ingredients and performance are similar to Oxy cleaning products. The manufacturer needs to improve the directions to more precisely describe the suggested concentration of product. "a half-cup in a bucket of water" is not useful (is the bucket assumed to be 1 gallon? 5 gallon? 30 gallon? I use a third of a 90 gallon trash can - so how much do I need for 30 gallons? I wound up using a full 1-pound bottle to about 30 gallons of water (about 3 cups, or 6 half-cups per 5 gallons). I have a 15K gallon pool that uses four larger Hayward filters. I hose-rinse them quarterly, and annually I swap out with a second set for a week-long soak in a 55 gallon trash can to deep-clean and dissolve embedded grease and oil organics. I've previously used the hazardous acid products that worked very well, but also dissolved my concrete driveway when I dumped out the used product - that worked very well to clean and bleach the filters. The Oxy product costs less, worked about 70% as well (not as bright, and I could feel oil left on the rubber ends), and didn't etch my concrete drive when I dumped it out.
