Ultimate Spa Filter Cleaner Fast-Acting Spray. Instant clean for Hot Tub & Pool Filters leaving behind no sticky residue. Prolongs filter life and pool equipment. No soaking. (1-Gallon)

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.

I’m a huge skeptic when it comes to products that make maintaining your pool or spa easy. I read the reviews on this product and decided to give it a sho and am I glad I did. This is by far the best and easiest way that I’ve found to clean your filters. I use a spray bottle and just coat the filter and let it sit for 30 minutes and then rise with my hose. You should see the stuff that comes off the filters. They look like brand new every time. I will buy this product as long as it’s available.

I finally used this product today and it seems to work as well as another filter cleaner that I had before that I got from my hot tub dealer, but I will say as someone else mentioned the spray bottle container that it comes in is defective. It’s like trying to screw it on and the threads are already stripped because no matter how many times I tried to secure it, it wouldn’t stay on and before I knew how bad it was it ended up falling to the ground and splashing up all over me. Luckily, I was outside but it got all over my skin so I had to go inside and quickly wash it off. So again good product, but it needs to be in a better spray container. I’m going to be switching this over to an empty spray bottle that I know works.

I have been using this for several years to do maintenance cleaning of my hot tub filters. Spray it on and let it sit a few minutes then rinse off. Water in the tub is crystal clear.

The product arrived quickly but I haven't used it yet, so can't really comment on its effectiveness.

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 have found that this is the easiest way to clean my hot tub filters on a monthly basis

Worked just like was stated...cut my filter cleaning time down!
