Cleaning and sealing rough cedar siding
I have just bought a cabin with what I believe is rough cedar vertical board and batton siding. No one has lived here permanantley for many years and the east and west sides are silvered, while the north and south sides still retain their color and appear to have some sort of stain or sealant on them. See the image below.
I'd like to retain the natural cedar look of the cabin. And I have two questions:
I've read about something called 'oxygen bleach' (not regular kind) that's supposed to be able to restore the original color of the wood - does this really work and is that all I would need to do to ready the siding for stain or sealant?
And which is better to use for a relatively long-lasting finish that will match the original: sealant or a stain?
