We had a fairly large cedar deck built onto our house a little over a year
ago. The contractor put a clear water sealant on (we didn't want a brown
stain, opting for the natural look). Now the wood has a lot of black spots
(probably from the overhanging trees), and the cedar has a whitish coat,
which appears to be normal aging. There's not a lot of direct sunlight on
the deck, because of surrounding trees. I tried cleaning thew ood with a
strong household cleaner, but it takes a lot of elbow grease. I would rather
not use a commercial deck cleaner, because it is toxix, and our well is
As I see it, here are my options:
1) Scrub like hell.
2) Hire someone to pressure wash the wood.
3) Buy my own pressure washer for $175 and take a chance I won't damage
4) Maybe use an electric sander...the rectangular kind where the bottom
vibrates--for fine wood sanding?
After cleaning, I've already purchased a couple gallong of Sikkens Natural
Cedar stain (very small amount of pigment).
I know a darker stain would last longer, but my wife and I just love the
natural look of cedar, and we'd like to keep it looking new.
By the way, we live in Minnesota.
