Question for the experts in the WW thread...
I'm attempting to 'refinish' the wood paneling in my basement by sanding off the existing coating to reveal the underlaying original wood (see 2nd picture for 'after/before'). There are some areas (particularly near the top of the boards) where there is some discoloration (staining?) from what appears to be where the old drop-ceiling used to sit (no ceiling since I've lived in the house) and also where some cabinets and a built-in bar were previously located.
What's my best bet to clean up these areas? I was thinking about trying some 'wood bleach' (oxalic acid), but I'm curious if that will be 'too aggressive' -- is a continued sanding effort my best approach? TIA for any shared insights.
