DEFY Wood Brightener

DEFY Exterior Wood Brightener is an oxalic acid deck brightener that removes dirt, grime, tannin, rust, and fungi stains from wood surfaces. This liquid concentrate is mixed with water (four parts water to one part concentrate) to brighten and restore the natural beauty of exterior wood. DEFY Wood Brightener will not harm wood fibers, grass, or most plants when used properly. DEFY Wood Brightener is recommended for surface preparation prior to initial application of clear and semi-transparent finishes and stains. It is used as a neutralizer and brightener for all wood species that have been cleaned with DEFY Wood Cleaner or DEFY Wood Stain Stripper. For best results, use DEFY water repellent wood stain finishes.

Even new wood needs to be cleaned in order to remove mill scale so the surface can more easily absorb deck stains. DEFY Wood Brightener is the second step in a three step process to maintain your deck and keep it looking like new. The three steps are:

1. Clean or strip using DEFY Wood Cleaner or DEFY Exterior Stain Stripper
2. Brighten and neutralize using DEFY Wood Brightener
3. Apply DEFY Wood Stains

DEFY Wood Brightener is a liquid concentrate sold in one-gallon containers. One gallon of concentrate will make five gallons of solution and will clean approximately 500-1,000 total square feet (or 100-200 square feet per gallon). DEFY Wood Brightener is not formulated to remove intact paint, stain, or clear finishes and may dull painted and metal surfaces if not quickly rinsed.
