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

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.

I have purchased this product multiple times. I've used much more expensive spa filter cleaners but this soak product works better or just as well when dissolved in a 5 gallon bucket.

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.

These are before, during and after photos of pool filters. The pool is surrounded by oak trees. During April and May they drop a lot of leaves and pollen into the pool. The filters get very dirty. I change filters every 4-6 months. I keep two sets of filters and clean them when changing them out. The filters in these photos are on their second rotation and will be replaced after their next use. They had been pressure washed before this photo. They don't look perfect, but they look a lot better in this photo than they did when I took them out. I knew they needed more cleaning, so I then put them in a 55-gallon drum of water and two 1-pound bottles of Spa Depot Power Soak. (Was a guess on the water to powder ration) The second photo was taken the next morning after soaking overnight. I was surprised at how dirty the water was and how well the Power Soak worked! I pressure washed them again. There they are in the last photo. They don't look new, but they are cleaner than just power washing can get them, and they will work one more time and that cost less than replacing them. I can recommend Spa Depot Power Soak!

I think I have purchased just about every filter cleaner Spa Depot sells for over 20 years. (Plus a few others). I have oily skin, even after showering, and filters can be hard to clean. I follow the hot water directions and soak them overnight in a small plastic bucket. They rinse out quickly and completely with only one soaking.

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 better than the liquid that I bought, but it’s still them clean the filters that well and then I had a pail of toxic waste

Best product for the money to clean spa filters. Just soak and spray off. Easy to use.

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!

It worked as indicated.👍

Great product

It works, but outrageous price in Canada. It's almost 1/10th the price compared to US. It does work however. Just can't justify

Doesn't clean as well as advertised. I have used this product many times and it has never fully cleaned my hot filters. I have even tried a separate second cleaning cycle on the same filters and they still did not come fully clean. The old (filter cleaning) potassium permanganate powder that I used to buy (not available anymore) always did a thorough cleaning of my hot tub filters.
