Cleaning solution: A wood cleaner and brightener suited to cedar.
What to know about cleaning cedar
Cedar decks and fences turn silver-gray as the surface weathers. Gentle cleaning with a wood cleaner and brightener brings back the color, and a penetrating stain keeps it longer.
Avoid: High pressure, which gouges the soft wood and raises the grain.
How often: Clean yearly; refinish every 2-3 years.
