Either IsoPropol Alcohol, or Acetone will take care of the problem. Be
sure to use some 3 in 1 oil on them after cleaning.


Most commonly available isopropyl alcohol contains a fair amount of water,
typically around 30%. I wouldn't use it for cleaning a precision tool.


Then it is not isopropyl alcohol; it is 70 percent isopropyl alcohol,
commonly sold as "rubbing alcohol". Isopropyl alcohol specifies just that,
isopropyl alcohol, not a dilution thereof.
