Pool filter cartridges. How to clean

[RTonk]

I have a Pool cartridge that has to be cleaned, rather than just rinsing it off.
What kind of solvent do I use?
Thanks, RTonk

TSP works the best for me but it can be hard to find the real stuff anymore. They have a substitute now that is more environmentally friendly but like most things, it doesn't work very well.

A lot of people used to soak them in electric dishwasher detergent.

If you have access to a pressure washer, try pressure washing it

I would avoid a powered pressure washer. A standard hose with a nozzle is fine but most pressure washers have enough power to easily tear the fabric in a cartridge filter.

Using a pressure washer can destroy cartridges instantly. Here are some 2013 pics of cartridges at a local fitness center that had been pressure washed:







These were very expensive StaRite System3 cartridges. They had multiple filters, and had to spend over $2,000 buying a single new set for all filters.
