Fonctionne à merveille
Au début , j’étais septique sur se produit mais j’ai décidé de l’acheté car nettoyer mes filtres de spas me prenait un temps fou. Utiliser pour la première fois aujourd’hui et se produit est merveilleux, j’ai vaporisé tout le tour de mon filtre , attendue 3-4 minutes et j’ai rincé avec mon boyau d arrosage et en 2 minutes mon filtre était comme un neuf!!! Je vous le recommande

No soak!
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.

Excellent product
A little expensive but does what it's supposed to do.

Product good, container it comes in not so much!
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.
