How to Keep Cedar From Turning Gray

Sweep or brush off the cedar area completely with your broom, removing any large debris and any dirt that can be brushed off easily.

Mix the exterior wood wash, according to package directions, with water in the large bucket. Apply the wash mixture to the wood with rags and scrub, as needed. Use your stiff brush to work the wash into any areas with stains or large amounts of dirt.

Clean off the wood wash mixture using a power washer or garden hose. You will know you are finished when the water runs clear, and there are no more soap bubbles remaining on the wood surface.

Dry the cedar. This will normally be done by simply leaving the surface alone. If you are working with a small area or are under a time crunch, you can use fans to speed the process up, placing them so they blow air over the wood. Plan to allow the wood to dry for at least 48 hours.

Sweep the cedar once again when it is completely dry. This time, you want to sweep it lightly, just to remove any dirt that has settled within the last few days.

Brush the wood sealer on the deck using a large paintbrush. You want to remove any extra sealer by brushing it onto another, unfinished location or just brushing it back into the can. You can choose to use a clear sealer or you can use a colored finish, if you choose. If you are using a colored sealer, make sure the color looks even during application. Allow the sealer to dry completely before using the cedar.
