Does anyone know what I should do with the oil when the metal has been used ?

Reuse it by cutting more metal pieces ready for us and store them in the oil?

I seem to have 'ye olde' oil being used here with 1990 on the glass container - still keeps everything stored and inert.

Thank you so much for your answer, but we already have several bottles of "olde oil "

Well the oil is there to stop the metals from oxidising so if it is doing its job correctly then the used oil is just oil, there shouldn't be any metal residue in it so just dispose of in the way you would usually dispose of oil. In our case, that's down the sink if it's only a small amount.

The few times i have disposed of the oil alkali metals are kept in I have added the oil to some washing up liquid and then poured it down the sink with plenty of water. as there should be no alkali metal in the oil this should be safe.
