Hi All:

      I need to clean some engines that have old castor oil 4 decades, on and in them.  What will remove this varnish?  How about paint stripper, oven cleaner or??

Berrymans  Carb cleaner in the gallon dip bucket, or antifreeze in a crock pot will do the trick

    No caustic chemicals!  Crock pot with plain old green Prestone anti-freeze is the gold standard. It's as close to a miracle cure as I have seen in my 40+years.
