Paint Stripping Problem: Stubborn Residue in Oak Grain
From contributor G:
You could try Peel Away, environmentally friendly, non-drippy. I used it to remove grain filler on walnut that didn't take stain. Used a fine short napped gold wire brush, probably one from plumbing, and after an application wired with the grain. Saved the piece.
From contributor L:
If it is milk paint you may have trouble removing it.
From contributor K:
A sodium hydroxide (lye) solution will remove milk paint. Soaking and scrubbing may be necessary. Rinse with water. Afterwards, apply a solution of oxalic acid (sometimes labeled as "wood toner" or "wood brightener") to neutralize the lye and lighten the wood. Rinse with a solution of vinegar and water.
From the original questioner:
Thanks for all the responses. I think I may not have explained myself clearly. I have gotten most of the green paint off down to the bare wood, but there seems to be some hint of green still in the grain. If I go to stain this as is, I am afraid it won't look right. Do your responses still hold for this problem as further explained?
I tried another piece of oak with vinegar and water and the wood turned grey. Is this common? Also, I have let the stripper on (ZAR) for approximately 15 - 20 minutes in my attempts. Would another type of commercial chemical stripper do? I don't think it is milk paint.
From contributor R:
Use one of those brass bristle brushes that was mentioned earlier.
From contributor D:
There are some primers that don't respond well to removers, but will come off with lacquer thinner. Try scrubbing with a metal bristle toothbrush.
