Prepping headgasket mating surface
I pulled the head off my car to replace the head gasket. Took the head to the machine shop where they milled the gasket surface of the head. Do I need to wipe down that fresh surface on the head with alcohol or acetone or anything else? What about the surface of the block?

i would use a bristle disc/pad on that. dont use a razor blade though it will gouge that aluminum. ive used razor on d-series motors that use the composite gaskets since they seal pretty good but the steel ones need a clean and smooth surface. subaru guys use a big sanding block but ive never done it that way.
obviously best way is let a machine shop touch it up slightly so it matches nicely with the freshly surfaced head

wiping with a clean rag soaked in brake pars cleaner is a good final prep for mating surfaces before assembly.

I was very careful with the razor scraper to not gouge anything, but since the possibility is there for damage I guess I won't use it anymore.
Cool I have both carb and brake cleaners in the garage. When you say Scotch-Brite you're referring to those scrubber sponge pads right?
