My dealer has me washing my TriX ceramic filters once per month with a regular hose - they say they are top-shelf dishwasher friendly. But I personally haven't done that. My dealer said to use a Vinegar solution once per year to de-scale the filters (Basically soak the filters in Vinegar for a day then rinse thoroughly). I haven't gotten to that stage yet, I might buy the official Hotspring filter cleaner and use that first, then a followup soak in vinegar before rinsing and re-installing.
I usually spray my filters from the inside out with the hose sprayer, then I place it on a PVC pole strapped between two posts (handrails for steps) and hit it with the sprayer so until it starts to spin up and splash everywhere - makes a damn wet mess but the filters seem to stay clean and my water stays crystal clear with minimal maintenance.
I've been tinkering with my 3D printers to develop various prototype sprayer systems to clean the filters. Every month I test out a new prototype design. Most of my tests have been failures but I'm gaining a lot of knowledge in the process. I've gone through half a dozen different prototypes and still haven't found anything which does a better job than a simple hose with a jet spray nozzle attached. Oh well, this pandemic lockdown has given me the perfect excuse to continue tinkering with some of my more elaborate ideas for a filter cleaning machine.
I'm looking forward to sharing my results with the community once I have some sort of working proof of concept
