Pressure Washing
Pressure washing is the most common way to clean and prepare your deck prior to staining or restaining. Pressure washing removes most of the
old stain depending on the number of coats that were previously applied. Tannins in natural cedar and redwood bleed out over the course of time which makes the
wood gray or black in color.
Commercially available conditioners, cleaners, and brighteners can be applied with a pump sprayer and will help restore the original color of the wood.
Oxylic acid added to the spray mixtures neutralize the tannins and helps remove the gray and black colors.
I find that spraying at 3200 PSI removes most all of the dirt and tannins, and restores the natural beauty of the wood. Allowing the wood to dry for a full day to two days
is recommended prior to recoating with the stain of your choice.
