I recently did a compression test (seems normal) and in doing so noticed that there is a lot of "gunk" in the spark plug holes. I'm not sure if this is built up anti-seize or what, but it is concerning as during the process of removing/installing spark plugs I'm concerned that some of this crap could fall into the cylinder.
Is there any way to clean this? I don't want to start scraping it with the plug out for obvious reasons. Some of it looks "crusty" and dried on. Starboard was worse than port for some reason.
