Most
deck cleaners should be left on 5-15 minutes before scrubbing the deck or lightly power washing. You should apply the
deck brightener the same day that you are completely done cleaning. The brightener should stay on for about 15 minutes then only needs to be rinsed off. Dry time should be around 48 hours before applying the stain. If it rains lightly in between, wait another day. Heavy rain, another 2 days.
