How to Remove Mill Glaze from Wood


Darryl asked: How can I remove mill glaze from new, smooth Douglas Fir? I purchased it at Home Depot, so the wood is rather fresh (green). I don’t want to sand all the wood and would prefer not to use toxic cleaners like oxylic acid. Specifically, I was hoping something like 20 Mule Team Borax would remove it, but don’t know the right concentration, or if it would even work.

Every piece of wood comes with a mill glaze that protects the wood throughout the production process. This can be removed by washing it off with a glaze remover or leaving it to weather for several months. Once the glaze is removed, the wood will be able to take stains, etc. as the surface is now exposed.

You Will Need:


  • Glaze Away by Biowash (or other glaze remover)
  • Water
  • Bucket
  • Soft cloths

Steps to Remove the Glaze:

  1. Mix the glaze remover with water as directed on the package.
  2. Apply to the wood by spraying it on, or wiping with a cloth moistened with the mixture.
  3. Allow it to set for the recommended time.
  4. Wipe away and allow the area to dry.

Additional Tips and Advice

  • A light sanding of the surface can also be used to remove the top surface, including the mill glaze.
  • There are acidic products available and a bleach and water solution is sometimes used to remove the glaze. However, these affect the pores of the wood and may alter its ability to accept stain. A glaze remover is the best choice.
