How do I clean this area of the cylinder head? It's the hole where the spark plugs go into. I was able to clean about half way in but now the plug is in the way. Obviously, I'm not removing the plug because I don't want any fluids or grime going into the combustion chamber. Also, removing the head is not an option.
Any tips on how I can clean this area?
