Perform the cuts necessary for the PVC pipe segments.  It is easier to work with smaller sizes and cut first, rather than working with large segments.  You will want to work with each small section at a time, as you will need to act hastily before the acetone evaporates.

Work outdoors or in an open garage.  Acetone emits vapors which are harmful and can cause dizziness or headaches.  It may be best to use a respirator when working with Acetone, just as a precaution.

Use gloves when handling acetone.  You will want to use the heavy, yellow kitchen gloves, as the acetone will break down thin latex or nitrite (blue) gloves.

Apply a small amount of acetone onto steel wool by tipping the acetone can into the steel wool pad.  .

Quickly work the surface of the PVC pipe in a circular motion.  Concentrate on the areas of lettering and bar codes first, as the acetone will evaporate quickly

Work quickly.  Immediately wipe away the ink and smears with a clean cloth rag until they disappear.

Yellowing of plumbing grade PVC pipe is typical and cannot be removed.  This is due to a chemical reaction between the plumbing-grade pipe and ultraviolet radiation from sunlight or flourescent lighting.  Due to this, plumbing grade PVC will never match the whiteness of our Furniture Grade Pipe or Fittings unless painted or replaced with our Furniture Grade PVC Pipe, as Furniture Grade  products have a UV-protective additive.
