Why Bleach-Free Cedar Cleaning Restores Eugene Decks Without Rotting Wood?
Why Bleach-Free Cedar Cleaning Restores Eugene Decks Without Rotting Wood?
Bleach ruins cedar deck lignin, leading to wood splintering and gray weathering. We use sodium metasilicate wood wash to restore wood warm golden colors safely.
Why Is Chlorine Bleach Dangerous for Pacific Northwest Cedar Decks?
Chlorine bleach is a strong oxidizer that breaks down wood lignin, the natural glue holding wood fibers together. This causes the wood to become fuzzy, splinter easily, and lose its structural strength. Bleach also washes out natural cedar oils, leaving wood dry and prone to cracking. Additionally, bleach runoff can kill surrounding plants and lawn.
How Does Sodium Metasilicate Wood Wash Safely Restore Weathered Cedar?
We clean wood surfaces using a professional wood-restoration system:
- Sodium Metasilicate: A biodegradable cleaner that lifts organic growth, dirt, and gray UV-damaged wood fibers without breaking down wood lignin.
- Low Pressure Rinse: We rinse at under 800 PSI to wash away dissolved organic matter without gouging the wood.
- pH Brightening: We apply an oxalic acid wash to neutralize the wood’s pH. This opens wood pores and restores the bright, warm natural golden color of the cedar.
- Plant Safe: Completely safe for surrounding garden beds, landscaping, and lawns.
How Does Oxalic Acid Brightening Bring Back the Natural Warm Wood Tone?
After cleaning wood with alkaline sodium metasilicate, the wood pH becomes high, turning cedar dark. We apply a second-step oxalic acid wash. This neutralizes the wood’s pH, bringing back the natural golden cedar color and opening the wood grain, which improves sealer and stain adhesion.
Case Study: Cedar Deck Restoration in Friendly Area (97405)
We restored a large, gray cedar deck in the Friendly Area (97405) that was covered in green algae and mildew. The homeowner wanted to stain the deck but was worried about chemical damage. We used our two-step metasilicate wood wash and oxalic acid brightener. The deck was restored to its warm cedar tone without wood raising or splintering, providing a perfect surface for stain application.
