    • No soak!
Size: 1-Quart
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. ... show more

    • Product good, container it comes in not so much!
Size: 1-Quart
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. ... show more

    • Top quality product
Size: 1-Gallon
I was a little skeptic because the videos showed amazing results. Purchased the product followed the directions five minutes on amazing the dirt just poured off the filter 10 minutes later. The filter was crystal. Clear look like I was just brand new. Highly recommend this product.

    • Miracle Cleaner
Size: 1-Gallon
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. ... show more

    • Frequent spills
Size: 1-Quart
Considering that the top does not screw onto the bottle and I have literally spilled this every time I use this, I’m rating this product a generous 3.

This is excellent for cleaning spa filters. Spray it on and let it soak in a little while and spray it off well. Good as new!
