Help please! My husband and I have ourselves in quite a pickle. We have a 1 year old cedar deck that was built last summer in South Dakota (extreme temperatures and both snow/rain). Last winter was fairly mild and we did not allow snow to sit on the deck but the wood had weathered and had small speckles of mold. We got around to prepping the deck for stain a couple weeks ago and am now realizing we made multiple mistakes. We first pressure washed then sanded everything with 120-220 (based on incorrect advice from a local hardware store- first of many mistakes). We then used a deck cleaner, and although we thoroughly washed after, we didn’t do the deck brightener until hours later. The wood then looked white or bleached in areas with some white fuzzies. So we started sanding with 80-180 grit to get rid of the white. Now after reading your sanding post, I believe we cannot stain as the pores are closed due to the finer grit, correct? What should we do about the white/bleached portions that are not fuzzy- Will it take up stain or do we need to sand it down to the raw wood as we had started to? It is mid September and I am worried about leaving it all winter again. It likely will not be nice enough to stain until at least May if we have to wait.

Sand all wood with 60 grit. After, use a deck cleaner and then a wood brightener. Apply 1 coat of a penetrating deck stain.
