Paraffin gel with additives. Paraffin alone makes quite a good

Years ago (when I was young and stupid(er)) I discovered that cleaning
my mucky oily hands in clean engine oil or kerosene really worked.

spotted me doing it and informed me with some passion that I was
cruising for skin cancer.
I haven't done that since and have (nearly) always used barrier creams
too.
