Ultimate Spa & Pool Filter Cleaner Spray, Professional Strength Fast Acting No Soak Hot Tub, Cartridge & Sand Filter Cleaning, Removes Body Oils, Sunscreen, Grease & Organic Build-Up (4 gallons)

This stuff worked Great! This plus the water comb I used got my filters looking like new again. I let is sit a bit longer than advised, but it definitely got them cleaner than I have been able to in the past.

If I hadn't tried to clean other filters with my own ways, I wouldn't have fully appreciated this product. I'm always reverse engineering product ingredients (science background) and using what I have or can order to do the trick. Each time previously I could wash the filters yet still see the dirt in the fins. I usually ended up just replacing the filters. I tried that for 2 years and then I gave this a try. It visibly removed the dark sludge from the filter. I wish I'd have recorded it. I'll try to record next time and update. I'm sure the ingredients are available in another product, but I'm not spending any more time trying to save five dollars. I'll keep buying this .

Love this to clean my swim spa filters , works great !

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.

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've used the overnight soak method with my last spa filters. Dragging buckets around, sloshing water, the wait, and the sometime residue that would bubble in the spa. Not with this product! Spray on the dirty filter, do a quick chore for a few minutes, (or sit with a cool one), and then rinse the dirt and debris out with your garden hose. Dirt gone. That fast. No slime, no product residue, no overnight. Quick, easy, and clean. Tip: I've found that if you change your filter, and don't have any time to clean it right then, come back to the dirty filter and give it a quick water spray to wet it first. Then spray with the filter cleaner. Good as new! No residue bubbles in the spa. Fantastic product! Thank you seller!

Works really well and easy to use! Seems to get the filters way more clean than just water spray!

Was recommended to use a product like this one when I got my hot tub and i'm glad that I do. It helps get all the scum off of the filter that gets sucked Into your filter and it smells nice and doesn't leave any type of a residue in the water after from what I can tell. I really like this product

Cleans up filter really quick

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

The chemical seems to work good but the spray bottle has issues and won't tighten so when your trying to spray the filter the bottle wants to come apart. I ended up putting it into a dollar store spray bottle which works better
