For the wooden parts of these tools, I am going to use a 'reviver' mixture. There is nothing original or difficult about this. It's been mentioned by several people on here who have more experience than me but somehow it's something I had not got round to trying before.
There are various recipes for the reviver. This one has equal proportions of boiled linseed oil, white vinegar and turps substitute, plus 1/4 that amount of meths, and a dash of ammonia. The proportions don't need to be exact and recipes vary quite a lot, some missing out the meths and ammonia.
Mix it all up in a suitable bottle, LABEL IT! and shake well. The ingredients do settle out quite quickly, so I found it convenient to pour just a little into a dish from time to time.
Mi piacerebbe che qualcuno che sa l'inglese meglio di me mi aiutasse a tradurre le sostanze che vengono usate ed eventualmente qualche nome commerciale...
