Pro-Kleen MY1437 Hot Tub, Pool & Spa Filter Cartridge Cleaner 5L-10 Treatments-Improves Efficiency-Deeply Cleans and Removes Oils, Grease and Minerals, Multi

We are nearly a year into the bottle now, and its still got about 500ml left. It has let me cycle through 3 filters all year from heavy use with a family of 5. Its stopped us throwin them away and has made them last 10x longer. Great for everyone. I just use a hose on the filter with a fine spray to clean up, place them in a bucket and cover with water and add a generous gloop of this stuff and leave for a few days. Afterwards quick rinse off and they are good to go.

Does a banging job - the filter after sitting in the solution was pristine, but the water was definitely not! I always give the filter the best clean I can before and after. I try not to let it get into an awful state but sometimes after a heavy party it happens and letting it sit in this (diluted) for 12 hours totally saves it. I've had my hot tub for 4 years now and own 2 filters that I interchange and haven't had to buy any others yet thanks to this stuff.

Works well, will buy again when I run out.

This works very well

This filter cleaner works really well - I regularly clean the filters with a high pressure hose which removes a lot of debris and returns the filters to a bright white, giving the impression they're clean. I followed the same routine and then soaked the filters in this solution for 24 hours - the colour of the water the following day turned my stomach! Suffice to say, this cleaner gave my filters the deep clean they needed! Great value for money with the 5l pack.

If you’re a hot tub owner then you’ll know you have to keep your tub filters clean. They catch all Kinds of dirt and grease and so you need something that you can put in the filter that will help you get rid of the dirt and grease. I use a plastic tub which I submerge the filter in and add this chemical with water and leave them for 24 hrs to soak. After 24 hours a simple wash down with the horse-pipe and the filters are clean and ready for next use. To stop dust getting on the filter prior to re-use, I wrap the filter in cling film. Job done.

Came quick. Easy to use and cost effective in 5 Litres. Will order again.

Nicely cleaned my filters, which I was going to replace. Best to let the filter soak over night/24hrs. The colour of the water was evident of the cleaning process, yuk!
