What to Consider
Cleaning purpose (routine maintenance, pre-stain prep, or stain stripping), product type (oxygen bleach, sodium percarbonate, oxalic acid brightener, or chemical stripper), wood species sensitivity, environmental impact and plant safety, pressure washer PSI rating and compatibility, coverage area per container, and whether you need a single product or a multi-step system.
Product Comparison

Size Selection Guide
Concentrated cleaners typically cover 100-200 sq ft per quart when diluted. A 2.5-gallon kit of a complete system like Restore-A-Deck treats approximately 500 sq ft. For routine annual cleaning, 1-2 gallons of cleaner and 1 gallon of brightener cover a 300 sq ft deck. Stain strippers are more concentrated and cover 75-150 sq ft per gallon due to heavy application.
Installation Tips
Wet surrounding plants and cover gardens before applying chemical cleaners. Apply cleaner to dry wood and let it dwell for 10-15 minutes (do not let it dry). Scrub with a stiff bristle brush on stubborn areas. Rinse thoroughly with a garden hose or pressure washer at 500-1500 PSI (too much pressure damages wood fibers). Always follow cleaning with a brightener to neutralize the cleaner and open wood pores for staining.
Common Mistakes to Avoid
Using a pressure washer at too high a PSI (over 1500 for softwoods) which furrows and damages the wood surface. Skipping the brightener step, leaving the wood with raised pH that prevents proper stain adhesion. Using chlorine bleach which breaks down wood fibers and kills surrounding plants. Letting the cleaning solution dry on the wood before rinsing. Cleaning on a hot, sunny day when product dries too fast.

Budget cleaners cost $10-15 per gallon. Premium wood-specific cleaners run $15-25 per quart concentrate. Complete strip-clean-brighten kits cost $30-60. Wood brightener costs $12-20 per gallon.
