I have a (northern white) cedar swingset, which I stained as soon as I
purchased it 2 years ago. I know it doesn't need staining, but am not
partial to that natural grey color it forms.
Didn't re-stain it the following year, and now it's starting to look
ugly with water marks, maybe moss.
What's the best or easiest way to prepare the surface before
re-staining it? I heard power washing soft wood like cedar isn't good.
Is bleaching (50/50?) good enough, or do I need to sand it?
