Review: Lasts ages, cuts waste, and keeps the filters clear. - 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. Review: Superb filter cleaner - 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. ## Features - Causes serious eye damage. - Causes skin irritation. - Part of the best selling Pro-Kleen Spa Range, this professional, powerful formula thoroughly thoroughly cleans the filter of hot tubs, spas and pools - Pro-Kleen's fast acting, highly effective, long-lasting formula!

Discard the water after soaking and rinse the filter with a hosepipe Under pressure to remove the solution - rinse until the water runs clear and is no longer frothy.. hope this helps **Q: I'm getting no results from this at all, can anyone advise please? Using cleverspa with chlorinated, pH and stability levels correct the water** A: This is a filter cleaner you don’t add it to the water, you have to soak your filter or filters in this solution which is diluted with water to the right ratio. Soak overnight and the results are great. **Q: Is the 500ml in 10l set, seems like a lot for a small filter, would 250ml in 5l have the same cleaning effect** A: Undoubtedly I am sure **Q: This is my second part to my question, my hot tub is a Master Spa 425 gallons.** A: This will clean all filters and pumps just follow the instructions ## Customer Reviews ### ⭐⭐⭐⭐⭐ Lasts ages, cuts waste, and keeps the filters clear. *by H***7 on 7 October 2025* We are nearly a year into the bottle now, and its still got about 500ml left.
