Great cleaner! It works for our salt water hot tub filters. Just spray, wait for several mins and rinse. Way better than dealing with those tablets and submerging the 2 filters into solution. Plus you can’t beat the price in comparison with this tablets. I’ve used it for a year already. Just got my second jug of it.

HONESTLY, AMAZING. Our pool gets a lot of algae outbreak due to tree coverage, so we are constantly rinsing the filter. Our relatively new filter was lasting about 2-hours before becoming ineffective and needing to be rinsed. So I bought this hoping to get 3-hours of use between cleaning. I was absolutely shocked to see that, once cleaned with the filter cleaner, our filter was registering as nearly brand new. For a fraction of the cost of a new filter, this product will extend the life and effectiveness of my current one.

Great Cleaner for pool filters. Spray it on, wait 10 mins, wash with a garden hose that has a nozzle.

Do it arrived with no damage or leaking BUT either I got a defective bottle or a defective spray cap because as soon as I attached the spray cap it seemed like it was on but detached and half of this went all of my kitchen floor (I cleaned up the other area before thinking to take a picture). Now... This is a $20+ bottle the size of a standard Windex bottle... That's expensive as it is let alone for half of it to be all over my floor. I tried several times and verified that the bottle and the spray cap DO NoT lock in (essentially making the spray bottle useless)Luckily I had a spare glass spray bottle and poured the rest of it in there. I am happy to report that this solution DOES WORK to easily clean grime off of my hot tub very easily/ fast without leaving any unwanted residue (and our hot tub is somewhat porous).I will be reaching out to Amazon to see if they can do anything to help me out with the fact that half of the product went all over my floor because of a defect and/or design flaw with the spray cap. Aside from that, I would have given it 4.5 stars out of 5... 5 out of 5 if the price was more reasonable.

I love it for a quick clean when I don’t want to do the soak.

Works, saved my dead pool filter. I used it every night but if that is what it took to keep my 40 year old pool clean ,so be it. This was a real winner.
