Filter cleaning

[Grib]

Can anyone recommend a good filter cleaner. I was told only rince filters with cold water but since found out they need to soak 12/24hr in cleaning solution any tips welcome. I have bought a second set of filters

I cannot recommend any - because since getting my spa in 1988 I haven't used one.  I just hose off the filter, and change it out once or twice a decade.

I think there are cleaning devices available to purchase, but I've never used any or even any brushes.

Remember - ANY detergent will causing foaming issues until the end of time....

I've been hosing out the filters like Cusser mentioned, and every 3 months or so have used vinegar diluted 50% in a pail just large enough to fit the filter in it, and let it soak overnight.  I have a spare filter, so I swap them out when its ready to clean. To be honest I'm not sure if this does anything, except waste a lot of vinegar lol.

Instead of a chemical cleaning, I started using my 3D printing & design experience to try improve how I physically clean the filters.  Took me a year of prototypes trying different things but I've finally designed something awesome and universal to turbocharge my filter cleaning.

Two years of testing and I'm really happy with my design.   I can't wait to share it with the community after I finish all the paperwork and such.
