The actual area where the plastigage was placed is clean, though it's hard to tell in the photo. I wiped the application area clean of oil and lubriplate prior to the application of the plastigage and retorquing the main cap. After taking the measurement I then clean the plastigage off with a little brake clean and then reapply the lubriplate prior to reinstalling the main cap and torquing to spec.
