Description
The Critical Step Most People Skip
After using an alkaline cleaner or wood stripper, the wood’s pH is elevated.
If not neutralized, stain adhesion can fail, leading to:
• Blotchy finish
• Poor penetration
• Premature peeling
• Uneven color
EXPERT Wood Brightener™ restores proper wood pH, brightens the surface, and opens the grain for optimal stain absorption.
This is not optional. It is essential.

✔ Restores natural wood color
✔ Neutralizes alkaline cleaners and strippers

FAQ
What does a wood brightener actually do?
A wood brightener neutralizes the high pH left behind after using an alkaline cleaner or stripper. It restores the wood’s natural color and prepares the surface so stain penetrates evenly and bonds properly.
Do I really need to brighten after cleaning or stripping?
Yes. Skipping this step can lead to blotchy stain, poor adhesion, uneven color, and premature failure. Brightening is not optional in a proper restoration process.
Will this remove black stains from cedar?
Yes. Oxalic acid is highly effective at reducing tannin bleed, which causes black or dark streaking in cedar and redwood.
Is this the same as a wood cleaner?
No. A cleaner removes dirt, mildew, and coatings. A brightener neutralizes pH and restores color. They perform completely different functions.
How long do I need to wait before staining?
Allow 48–72 hours of dry time. Wood moisture content must be below 13% before staining.
