For those who like to clean and reuse their old spark plugs

Cope said

My buddys dad used to have a mini sand blaster mounted to his work bench, made just to clean spark plugs.

You guys remember those?

I bought one last summer for outboards, tho I haven't used it much "yet." I have yet to find a very cheap source of abrasive. Old two strokes are hard on plugs

Not sure I would have bothered wasting time on a weak mix of Marvel oil for baked on plug residue. I've tried dip carb cleaner and acetone and was disappointed with results. I've forgotten, I soaked several plugs for at least a couple days
