Essential Values Pool & Spa Cartridge Cleaner (2 Pack, 32oz / 2 Quart Total / 4 Uses), Made in USA - Filter Cleaning Solution Comparable to Leisure Time

Don't spend your money on the pretty smelling pump bottle spray cleaners. Buy this instead and save a bunch of money and get your filters clean! Neighbor had his well worked on and I filled my spa a couple days later. Water had a reddish tint to it. My filters became stained brick red color. My spray bottle cleaner didn't touch the stain. I soaked my stained filters in this cleaner overnight and they came out snow white. And I only paid $8.50 for two 1qt bottles!

Cleaned out our hot tub filter pretty well. No issues with the product. After an overnight soak, the filter was cleared of all dirt and calcium deposits. This product was cheaper than what I used to purchase from the local pool store.

It works amazingly well, but it should be shipped with a Material Safety Data Sheet. It is a concentrated corrosive substance. Do not get it on your hands, skin or face. Be extremely careful with it. However … it did make two year old PA120 filters look like new filters, so I highly recommend it. Just be careful.

Ive used better but at this price i will continue to use. It does ok, better than some stuff i used. I do soak em overnight.

Pretty good product except for the price. $20 only cleans 2 filters.
