Not fair, you put in two questions here!
Please say you're going to ultimately seal/finish the wood later.
But one at a time.
Here was my solution to cleaning dusty unfinished panel that had a small
'drip' stain.
first keep as dry as possible use NO wet cleaners. remove all 'dirty' type
dust. Dust can't penetrate. So a 220, 330, or even 440 sanding helps knock
that dust off. Use a paint tac rag to clean off after light sanding.
Now you have a clean surface but a stain spot. Any water base is going to
raise the grain, so must be careful here. I have successfully 'spread' the
spot by cleaning and gently continuing it out until not noticeable. But is
tricky and requires a bit of learned skill. As in learn how as you do with
no way to go back and undo.
If this is down inside, out of view; screw it! Simply clean and seal and
be done.
