Springtime is a great time to get a refresher on the basics of cleaning wood decks.
After all, there is no better time to see exactly how your deck
faired over the winter time. Cleaning a deck on the other hand involves a
what to do to make sure you clean your wood deck properly and catch any
Use a stiff brush and sweep off the entire deck surface, around posts,
stairs and remove all debris.
Places to check are gaps between your deck boards over the joists. Make sure there is no wet debris wedged in there.
Take the broom and clean the gap between the deck and the house.
Sweep areas where stair stringers rest on a lower deck or a concrete
These area always vulnerable areas and need to be checked each year.
Wash Then Inspect Everywhere
Use an exterior wood wash solution and mop off all the wood surfaces making
sure sap, and other contaminants are removed from the surface.
This is the most important difference about cleaning wood decks over composite
decks because there are many places where rot and moisture can set in to
start the decay process.
Clean around railing balusters,
top and bottom rail and rail to post connections.
Elevate the stair stringers from the wet landing. Ideally keep them 1/2"
above the surface so they say dry.
Look for fascia board starting to warp of separate at corners and repair
Look also for water pooling on certain deck boards. Warped boards can catch
water and prevent drainage. This is the start of rot.
Use a belt sander
and carefully sand the board flat if its minor. Or else remove it and flip it over.
Also keep an eye out for any soft spots on the decking boards
where you notice water pooling and particularly if there are nails set
below the deck surface. These spots are candidates for premature rot
Fill all nail or screw holes on deck boards with an exterior wood filler
or even an auto body filler (if you cover it with a solid stain). Don't
let water pool in these little holes.
I think you get the idea. Basically, cleaning wood decks requires a much
more thorough approach if want your deck to last. But it can be done.
