spark plug wells and dirt buildup

so im about to change my spark plugs and vc gaskets....

but there is a mouse nest and other crap built up in the spark plug wells, which is then coated by oil thanks to the leaky vc gaskets.

i was able to use a shop vac to get most of it out, but there is still some down around the base of the plug, and im kinda stuck on how to get it out, and i dont want any shit getting down into the cylinders.

ive been using a pic and small screwdriver to try and brake most of it free, but with the oil mixed in, its sticking to the head and spark plugs pretty good.

any ideas while i sit here staring at it? :nanan?re
