Around three month ago I finished my workbench on wheels. When I made it I decided to oil most of the wooden surfaces. For two reasons: I’m lazy, and I like the touch and feel of wood which is not covert with a layer of resin.
What I’m doing on this workbench most of the time is exactly the opposite of clean. When rebuilding a classic bike you deal all the time with dirty oil, or oily dirt, rust and smut. Of course I clean the workbench form time to time.
Anyway I guess after a couple of years I can sand the dirt off and oil it again. Btw. I oiled the table top 5 times before I started messing it up.
