Petroleum Jelly (Vaseline). As tnom has stated it is eatable and worked
for me and a host of mechanics for over forty years. Even used it on poly
packing. Easy to see if contaminated and what the contaminate is. A metal
shaving or grit in a dark grease will lead to rework. The most expensive
work because it it at no profit and may ruin your reputation. Your
reputation is hardest part of rework to repair.
