Haha, we really got ourselves confused in here! Part of it is my fault for bringing up using light oil as a quick-clean on the stones. It’s not necessary by a long shot and a proper cleaning with soapy water will certainly do a better job. I just use the oil and dab it clean when it’s getting really loaded up and I don’t have time to clean properly. I have to stress the importance of a light oil, because anything that will get gummy will just make it that much harder to clean later on.
I started doing that after seeing some of Clay’s info on using soapy water to catch particles while sharpening. I think the first mention was on a youtube video on his channel, but it’s come up here on the forums before, too. I like the idea of keeping the particles from getting all over my work area, but I honestly had not considered the slurry being detrimental to the finish. In my case I very rarely polish beyond 1000 grit, so it might not be a problem at all for me and my usage.
Additionally I try to keep Teflon (PTFE) based lubricants away from places they don’t belong. Teflon got really big in the gun world many years ago, so everyone and everything had Teflon in it for a while… until people started to notice that it wasn’t useful or was outright bad in some applications. Teflon doesn’t like heat for example, so burning off oil with Teflon in it actually releases some nasty fumes! The oil I use for my impromptu cleaning is 100% vegetable based, just in case!
Man, all this talk reminds me to clean my stones good and proper
