Ive got some white corrosion at the bottem of my guides next to the spark plugs.Its not that much but I dont want it to fall into the head when I take the old sparks out.What can I clean the guides with safely?

Thanks

 

use a vaccum cleaner with an attachment at the end of it. It should work.

 

I tried the vaccum I can get on the side of the spark plug.

Also the walls of the guides are a light brown color.Is soap/water on a rag or something safe to use to wipe the guides down?

 

light brown=
white=lean
black=rich

not sure about how to get that stuff out if a vacuum didnt work
