Yes I was talking about bits used for wood. Thanks for the very useful tip.
I tried out this bit cleaner
http://www.woodcraft.com/Product/200...ump-Spray.aspx It cleaned the bits up in about 30 seconds. I could tell that my bits cut much better.
Then I decided to clean the rails and V wheels using the cleaner and I was amazed by the amount of grime that came off.
Bottom line, the wheels and rails looked clean but they were not and the bit cleaner did the job.
Thanks,
