Caring for pressure-treated wood

Pressure-treated pine is the most common deck and fence wood. It grays, mildews and gets slippery when wet. A wood cleaner does most of the work, and a brightener afterward restores the wood's color and helps new stain soak in.

Avoid: High pressure and narrow tips, which leave furry, gouged boards and lap marks.

How often: Clean yearly; restain every 2-3 years.
