Any way to dissolve bits of carbon/activated charcoal?
I've got a bunch of tiny grains of activated charcoal stuck in a fritted filter which severely hinders its use. Is there a good way to get this out?
I've tried forcing high pressure water through it with only mild success. I'm thinking maybe run a bunch of sulphuric acid through and hope it pulls
it out maybe? Is this viable or will it need a prolonged soak or something for that to be effective?

Soak, check out Piranha Solution. Be careful to make sure it is throughly water rinsed beforehand, small amounts of easily oxidized organics could
lead to issues.

Some claim the merits of WD40 which will apparently dissolve carbon to the point where you can wipe it off but not quickly!

An ultrasonic cleaner, maybe? Dimethylformamide can exfoliate graphite under ultrasonics. Activated carbon would probably disentegrate with similar
treatment. I believe a 50-70% solution of ethanol in water will also work this way, but not near as well. The best solvent to use for ultrasonic
exfoliation would be N-methyl-2-pyrrolidone.
I don't make any guarantees that the glass frit will survive the ultrasonic treatment, however.
