Cleaning RO/DI canisters

[advanwoerden]

Hi, I’m swapping out my RO/DI filters and noticed the inside of the canisters were very dirty. Seems like carbon residue + dirt. Should I clean them and with what? I tried wiping them off with a paper towel but didn’t really work. Admittedly it’s been a few years since I swapped the filters, definitely too long.

I personally doubt it matters.
