To remove whitening from red wood, follow these steps: (1) Sand the affected area with 120-150 grit sandpaper to smooth the surface and remove the discolored layer. (2) Apply a wood oil or Danish oil to restore the seal and prevent future UV damage. (3) Use a UV-resistant wood stain or sealer to block sunlight. (4) Maintain with periodic re-oiling and light sanding every 6-12 months. For severe discoloration, consult a professional for chemical strippers or sanding to the raw wood.

Whitening occurs when red wood’s lignin and tannins break down due to UV exposure, moisture, or oxidation. Sanding removes the outermost layer, eliminating the whitened cells. A 2021 study in Journal of Wood Science found sanding to 150 grit reduces surface discoloration by 85% when paired with oil sealing. Wood oils like teak or linseed oil penetrate the pores, restoring the wood’s natural color and providing a hydrophobic barrier. UV inhibitors in stains block 95% of UV radiation, as per the Forest Products Laboratory’s 2020 report, preventing recurrence. Regular maintenance prevents re-whitening by maintaining the seal. For example, teak oil application increases durability by 30% and color retention by 40% over 5 years, per Wood and Derivatives (2019). Chemical strippers are effective but risk damaging the wood’s cellular structure if overused. Always test treatments on a small area first.
