Worked amazingly well at cleaning out my sand filter. Wish there were instructions on how to do it, I had to get instructions from another company's website to properly do it. But it worked really well. Couldn't get my pool filtering at all, this cleaned it out and got it working perfectly again.

Ok, I really put this stuff to the test. I didn’t clean my filters the whole winter and they got pretty gross. I put this on and followed the directions. I sprayed a lot of it on the filter, let it sit for 5 minutes then hosed it off. It worked amazingly! I highly recommend. You can see in my pictures the difference.

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.

No soak needed — way easier than the usual filter cleaning routine I’ve used other spa filter cleaners before, and most of them require a long soak (which I never have the patience for). This one was a lot more convenient. I sprayed it directly on the filter, let it sit briefly, and rinsed — and it actually worked. It pulled out visible buildup and even removed staining that had been there for a while. The filter looked noticeably cleaner compared to just rinsing alone. What stood out: • No soaking required (huge time saver) • Broke down buildup quickly • Helped remove stains, not just surface debris • Smells surprisingly good compared to most cleaners After cleaning, water flow improved and the filter just looked fresher overall. It made regular maintenance feel a lot less like a chore. If you want something quick and effective without the whole soak process, this is definitely worth it.
