Wood vs. Composite
| Wood | Composite | |
|---|---|---|
| Pressure | Low — high pressure raises fibers and gouges | Low to moderate; check manufacturer guidance |
| Cleaner | Wood cleaner or brightener | Composite-safe cleaner |
| After washing | Let dry, then stain or seal | Usually no sealing needed |
Washing Before Staining
- Clean with a wood cleaner and low-pressure rinse.
- Use a brightener to restore the wood's pH and color, if recommended.
- Let the wood dry fully — often a couple of days.
- Lightly sand any raised fibers.
- Apply stain or sealer per manufacturer directions.
Fences
Wood fences gray and grow mildew over time. A gentle wash restores color and prepares boards for sealing. Vinyl fences clean easily with low pressure and mild solutions.
Frequently Asked Questions
How often should a deck be washed?
Annually is a good rule, with staining or sealing every few years depending on product and sun exposure.
Can pressure washing damage my deck?
Yes — too much pressure or holding the nozzle too close can splinter and gouge wood. Pros use low pressure and wide tips.
