Hi,
I was doing layout work on the surface plate on a 3 1/2 X 6 1/4 X 11 1/4" 7075 block, not thinking about the aluminum streaks on the granite plate until too late.
I know drain cleaners (sodium hydroxide) mixed with in a strong solution will make the bright smears to disappear but I'm concerned about the granite of the plate. This is a black granite plate if it makes a difference.
Thanks, for any help.
