I just finished power washing my deck. Not sure how old it is, but the wood looks good. It's been recommended I let the power-washed wood dry for a week or more before moving on to brightener. Would you agree? And after brightener (and rinsing the brightener), how long before I stain with a clear oil stain?
You do not wait a week after the pressure washing to apply a brightener. Brighteners (and cleaners) are used during the pressure washing process to aid in the outcome and for better overall prep. Apply the brightener now would best.
