BLUE BE GONE

BLUE BE GONE
Metal parts that are exposed to too much heat will turn a shade of Blue. I found that brushing white vinegar on the eye of the connecting rod, after heating to install pistons, removes the Blue. Put vinegar in a plastic container for dipping small parts, it works quickly. A couple minutes then a rinse and dry gets the blue out. The blue finish may not hurt anything, but it’s one less thing for some customers to question.
