In the winter my hands get to feel like 40 grit sand paper and it makes er, how shall we phrase this delicately, 'conjugal relationships' slightly tricky! Anyway, recently I was given a tip to help keep them nearer to 80 grit.
Simply pour a good dollop of olive oil into you palm, add a good measure of granulated sugar and 'wash' them for a while. Rinse off and they feel like new!
Right, I'm off to see of the missus would like a light sanding!
