I prefer not to use it myself but white spirit is a good option at the light end of the oily spectrum.Osvaldd":2c7v66y9 said:what lighter oil would you recommend then?
If you want something even lighter – with no oily feel, plus a more pleasant smell – then some use isopropyl alcohol on very fine hones (finer than 400 typically), although when you get to this sort of consistency there's a lot to be said for just using a window cleaner. For all intents one of these is the same as some of the posh honing solutions, at a tiny fraction of the price.
