I have some spark plugs that are heavily fouled with carbon deposit. Other than that, they are perfectly good.
Im looking for a solvent that i could soak the plugs in overnight, come back in the morning and the carbon would simply just fall off once brushed with a toothbrush. What solution can do that?
I tried wire brushes but it is not that effective and i feel that it does more harm than good. Also tried sand paper.It is extremely difficult to get in the nooks and carnies. Besides, it doesnt take off the carbon effectively. And more harm than good. What worked best so far is soda blasting the plugs. I would say it got %85 of the carbon out. The rest of the carbon was too time consuming to remove with a knife/screw driver. Also some parts of the plug i cant reach.
Soooo… i am looking for some kind of solvent that can break down the carbon once soaked in it. Anything?
