A perennial problem with heavy lumps of iron in the widely varying air temperatures at this time of year. Engines themselves aren't too bad, not many horizontal suraces where moisture can lie and in my case mostly covered with years of oily grime anyway! But what of machine tools? My lathe bed etc are always kept coated with a film of light oil, but last night I went out into the workshop to find that this had turned 'milky' indicating the presence of water. I wiped off and reapplied but I know it will be back. Any magic solutions out there?
