I am in the process of restoring an item of furniture that had been painted black, back to a wood finish. I started off by stripping off the paint with Citri-strip and sanding it until it felt smooth. At this point parts of the wood had a pale greenish hue and others did not, but I proceeded, just hoping it would be covered by the stain.
I started with Minwax Pre-Stain Wood Conditioner and followed it with a basic Minwax stain (yellow can). After the first coat I could tell it really wasn't absorbing evenly-- some areas were very, VERY dark while others looked more like what I'd expect after a first coat of stain. Apparently fairly dependent on how the wood grain had been cut on each piece. I could tell that a second coat would likely only make it worse.
I don't know what kind of wood this item is made out of but it is rather soft, and I don't know exactly what kind of paint had been on it either-- some kind of fairly hard enamel. It originally had a pecan-toned wood finish but was painted at some point in the 1970s.
My question is what should I do now to get a second chance at an even finish? My first reaction was to start sanding it down again to try to sand through the stain but I can tell it will take a lot of sanding to get through it. Should I just keep on sanding? Could I try chemically stripping it again? Once I get it back down to bare wood, what should I seal it with before staining so that this doesn't happen again? The Minwax pre-stain seems to have been inadequate for this wood.
Also, any idea as to why parts of the wood might have looked greenish? My best guess was that it was a byproduct of the paint, but I don't know.
