Happy Hot Tubs Instant Filter Cleaner Spray 2 x 500ml Hot Tub Pool Spa Tubs Spas

Good stuff. Use gloves as it melts the skin. Great for cleaning hot tub filters. 10-15 mins then blast off with water. Great results. Gets rid of makeup and skin residue.

Initially as others suggested I tried washing these filters in normal washing up liquid and got nowhere. However this stuff is amazing. See the images on this review which show a filter cleaned with this product next to one I had actually cleaned in washing up liquid. Completely different. I have also found that the cheap “ Addis ComfiGrip Tile Grout Stiff Cleaning Brush” is a great partner to this for these filters just the right size!). The procedure I have used is to remove the filter from the tub and whilst it’s still wet and warm spray it with this cleaner and agitate using the brush into the vanes and (which gets all the muck out deep in the base of the V slots you cannot get with your fingers and also as this stuff is strong using a brush is much better for your hands) and leave for at least half an hour in a bucket or small centre sink. Then agitate with brush once again and soak in water for another good while then just rinse off. I’ve cleaned a good few now and it’s only an inch down so a bottle will do a good load of filters. I highly recommend the seller “happyhottubs” also who dispatches quickly and packs excellently really good. The only slight negative feedback is they only dispatch ONE spray nozzle so you can’t share your purchase with a friend and have none spare for failures so if you want to I’d send them a note and ask them to send one spray attachment for each bottle!).

First time cleaning hot tub filter, worked well but does need a fair bit if rinsing out. Over all very pleased, would buy again.

Does its job!!!👍

I don’t often leave reviews but this stuff is amazing !! The amount of soap it creates when you are blasting it off with the hose is enormous. It is also coloured blue so you can see where you have sprayed and also missed. Plus, when you are washing it off the blue disappears so you are confident all has been rinsed off. I’m just going to use this weekly and swap my pair of filters while the latest ones dry off for the next week. I don’t even think I’ll do a monthly deep soak as I’m confident this stuff is nuclear powered. The filters are left gleaming white after. Buy them and be confident.

I have tried many filter cleaners and have found this one to be the best. It is so easy to use and cleans the filter to look almost new. Highly recommend.

This seems OK but it stains my filters blue where I have sprayed. Am I doing something wrong?

It's not bad. Very convenient but I think I'll be returning to sachets. You have to use a good amount roughly half the bottle if not slightly more per clean.
