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

Does a great job!

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!

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.

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.
