Wood Brightener

Cabot Wood Brightener is a professional-grade, oxalic acid–based formula lifts tannin stains and rust, returning gray or dull cedar, redwood, or pressure-treated lumber to a warm, new-wood tone with minimal effort. This ready-to-use 1‑gal size covers up to 200 ft² per application. Safe for use on cedar, redwood, pressure-treated wood, and even previously stained or painted surfaces (when the finish is sound) simply apply with pump sprayer or brush, allow 15–20 minutes, scrub stubborn areas, then rinse thoroughly.

• Restores wood’s original hue
• Ready to use
• Ideal as a preparatory step before using Cabot Wood Stripper or new stain/finish
