Stiff brush, then a flaming on SWMBO's gas hob is one of many ways.

Shortly followed by a flaming from SWMBO 
A brass wire brush is the normal tool for cleaning spark plugs. Giving them a toasting on the hob can help start a recalcitrant engine (useful for
old petrol mowers!)

I'd also suggest chucking them.
I mucked around for ages trying to clean some sooted plugs on the BEC after leaving it idling for too long... they never did work properly afterwards
even after cleaning....
Sorry
You can clean + bake if you really are keen but you might well be wasting your time or just encouraging the plug to crack + properly fail in a few
weeks  And of course sod's law being what it is it'll be on the coldest day of the year miles from nowhere with no mobile phone
reception..... Suddenly 8 plugs seems cheap(!)... At the very least if you clean them buy a couple to put in the car toolbox for such an occasion...

It never did seem to be a good idea to clean spark plugs with a abrasive powder then put them back into the engine. Probably taking some of the powder
with them.

Wire brush and then re-gap em.
If they are sooty because they have been in too long chuck em but as most plugs min 6k suspect they are sooty because you are running on the rich
side.
If they have ever been properly flooded they never seem they same again.

While I understand the reticence of reusing plugs, I think common sense has to prevail. Clean them, gap them. If they don't match the haynes
manual, bin them... don't bin them till you have examined them. Much cheaper to replace 4 than 8.

If they are just a bit sooty, I would sort out the mixture problem first
