Restoration Tips and Tricks

Wood Bleaching

Bleaching, is not just for white clothes. Yes, you can bleach wood but there are some important steps to follow.

Wood Bleaching Product Options:
  1. Household bleach – This can remove stains in wood, but will not effect the wood’s natural color. Also, in my experience it does not do as well of a job removing water marks other defects from age and wear.
  2. 2 Part Wood Bleach
  3. Oxalic Acid – This is commonly used to remove water stains and to even out weathered wood. However, because it is considered highly toxic I typically have opted out of using this one. Please do more research before making this your choice and get a good respirator.

I tested the first two today on these two oak tables. My client wants a gray-ish stain on these tables so I want to cut as much of the orange as I can.  Table on the left I am going to use a standard house hold bleach (100% undiluted). Table on the right I am going to use A-B wood bleach.

As you can see there are water rings in the wood as well. In my experience household bleach will not take those completely out.  I have already stripped and cleaned these tables. I have not done any sanding other than clean up with a #4 steel wool.

This one is the standard house hold bleach.  It just appears saturated.  The color remained unaffected.

Now I wait a few hours before assessing the progress… stand by……………….

Here we are after bleaching. You can clearly see the household bleach did not do as good of a job as the two part bleach. Note that two part bleach can clearly result in blotching.  Clean up and sanding usually takes care of that.

Neutralizing

It is important to note the role of neutralizing after bleaching. When you bleach your whites while doing laundry you always need a rinse cycle with vinegar to re-neutralize the machine. Same holds true with wood. If you don’t re-balance the chemical nature from the bleach, it will eat way at your clothes and make holes, or could damage your wood.

Wood Types 

Also note that different species of wood will respond differently to bleaching. After a tornado hit a local town, we were contracted to restore six cherry dining room chairs with water damage. We had to strip off the old finish and bleach the chairs because of the dark marks. The cherry wood had a bad reaction to the bleach and turned the chairs green! (Straight up green, I am not kidding.) We were so fortunate to have such understanding clients. We had to ultimately paint the chairs and cover up the cherry wood.

Thank you for reading this weeks blog! Let me know about your bleaching experiences.  Be sure to take caution when bleaching and work in a ventilated area too.

Happy Junking Friends,
