How to Remove Fuzzy Residue From a Deck

Larry Simmons

Pressure washing your deck is a fast and effective way to remove dirt or grime. It's also a way to strip a layer of soft fiber from the deck's wooden panels, leaving behind a fuzzy residue that can appear like carpet fibers across the length of the deck. This residue not only looks bad, but creates a surface unsuitable for any paint or finish you may wish to apply. You can rid yourself of the fuzzy residue, however, by sanding it away.

Step 1

Wait at least three days after washing the deck to sand the surface. You'll need the deck to be completely dry to ensure that all the fuzzy wood fibers are standing from the deck's surface, ready for removal.

Step 2

Attach 80-grit sandpaper to a random orbital sander.

Step 3

Put on work gloves, safety goggles, and a face mask before you begin sanding, to protect yourself from splinters and dust particles.

Step 4

Start in a corner farthest from the steps or entrance to the deck. Turn on the sander, and begin moving it down each deck plank in small circles. Move at a moderate speed, removing the standing fibers, but not remaining in place long enough to remove a layer of wood from the plank.

Step 5

Move to the next plank and continue the process, going from plank to plank until no trace of fuzziness remains.

Step 6

Switch to a sanding block and 80-grit sandpaper to sand away the fuzziness in any hard-to-reach areas, such as around railing posts.

Step 7

Sweep away the sawdust left from the sanding process with a stiff-bristled broom.
