Deck Cleaning and Sealing
Routine deck maintenance protects your investment and keeps your
deck looking its best. Before the deck is cleaned, any surrounding
plants and surfaces should be protected with water or drop cloths.
Then, any remaining sealant must be stripped or cleaned from the deck
by means of special wood cleaning/stripping chemicals. Typically, deck
cleaning products contain bleach to kill mold and mildew. The cleaner
can be applied by hand with a brush pole, with a hand pump-up sprayer,
or through a pressure washer. The chemicals are then allowed some dwell
time on the deck surface, to break down stains. This is followed by a
light agitation by the pressure washer, then an initial rinse and a
final rinse by the pressure washer. Some companies also apply a
neutralizer or a wood brightener after the final rinse.
