AFAIK OP, I've never personally heard of a way to de-foul used plugs. I assume it's because of the small cost to replace them. I would recommend trying to clean one in professional grade parts washer and seeing what happens. If you don't have access to that sort of thing, try carb cleaner.

There are spark plug cleaners of various types but they all seem to do about the same thing which is use air to sandblast the working end of the plug.

I have a small battery powered one for using when I'm out at the dunes.
They're only good on old style olugs- newer styles with those tiny friggin center electrodes will get destroyed.

gasket cleaner or sandpaper

WD40 or degreaser with sandpaper but from my experience they go shit again within half an hour. Just buy new plugs.

you can soak them in gasoline.

Petrol won't work though.

I've got new plugs. I want to keep these around as spares.

The problem with sandpaper or steel-bristled brushes is that the plugs have 4 electrodes and I can't get anything in there.

theyre like $15 who cares

Just wire brush and put them back in.

Switch to higher detergent Top Tier type gasoline to reduce the carbon deposits problem.

i bead blast fouled plugs for aircraft engines. Then wire wheel the threads and air blast the whole thing to make sure none of the bead blast media is on or in it.

aircraft engines run on leaded fuel so lead/carbon fouling tend to build up around the ceramic. So we use a jiggler with little narrow fingers to work the lead beads out of the cavity. don't think you need to do this for car though.

why dont you use new plugs?

beats me honestly. I guess cost. each plug is about 30 bucks and each cylinder needs 2 of them. so a 6cyl needs 360 bucks worth of plugs if we changed all of them.

service manual says to inspect and clean plugs every 100hrs and replace as needed. Its common for a plug to last multiple 100hr service intervals with out cracking ceramics or loosing spark. If its still sparky and free of cracks we keep using it.
