Here's a quick tip for ya that I picked up from another magazine. Many of us will clean our scroll saw bed (or any tool bed for that matter) with WD-40 and then put a coat of paste wax onto the bed. This helps protect the bed from rust and it helps your project slide easier when working.
Next time your bed needs a quick fix, grab a sheet of wax paper and rub down the bed. It deposits a thin film of wax that will protect your bed and makes your projects slide easier. It doesn't last as long as the method I described above, but it sure is quick. Pick up a roll of wax paper at the dollar store and you should be set for awhile.
