First of all, great site!
We have a white cedar deck in the Seattle area.
Probably last stained 5 years ago using Behr Semi-Transparent Waterproofing Wood Stain.
Used Wet & Forget and lightly pressure washed this spring knowing I would be re-staining this summer.
Best advice to remove remaining stain and brighten before staining again? Pictures should be attached.
Thanks for the help.
Strip off what you can using the Restore A Deck Stripper and these additves:
Sand off what the stripper cannot get off. Behr can be hard to strip fully. Brighten all wood when done.
