I have changed spark plugs before and have never come across these two small setbacks I'm having now.

I removed the wires from the spark plugs, and noticed that on two of them, there is an awful lot of black greasy gunk around them. Before removing them, I would like to get that cleaned up, to ensure that nothing falls in the combustion chamber. I bought carburetor cleaner for to use, and was planning on scrubbing around them with a small brush, then wiping it clean with a shop rag. Would that be a good thing to do?

I did try to remove one of the ones that didn't have so much gunk around them, but that one was in TIGHT. I tried using a little more force than usual to take it out, but it wouldnt budge, and I'm scared of breaking it or something. Is there something I can do or should I attempt to muscle it?
