How do I remove excess wood stain that dried before I could wipe it off?

Question

While staining some wood, we had an emergency and had to leave. The stain has now dried and I'm not sure how to remove the excess; it's normally wiped off before it dries.

When I get home I'm going to try to brush on some mineral spirits to loosen it up and wait about 30 minutes before trying to wipe off the excess.

Any other suggestions are appreciated.

Answer 1

If the wood feels smooth to the touch and you're happy with the color then I wouldn't worry about it. Some woods absorb extra stain without a problem.

If you are worried about tackiness

1. Apply mineral spirits with steel wool or a scrubby sponge. Clean the gunk off and dry overnight.
2. This may make the color splotchy or lighter than you intended. If so, a gel stain works well for evening the coat back out.

If you are worried about the color

If you want a lighter stain, you'll need wood bleach. Wood bleach is an iffy proposition, but your odds are good since you don't need to get it all the way back to the original shade and the stain isn't that old. I'm assuming in this answer you used a pigment-based stain (most are).

1. First apply the mineral spirits. This may lighten the stain some. Let it dry a couple days. If you're lucky, you'll be happy with this color and can finish with a clear coat.

2. If not, get some two part A/B wood bleach.

   This is a two part preoxide based bleach (NaOH and H₂O₂).

3. Put on gloves, goggles, respirator.

4. Apply the A chemical with a brush. The wood will probably look darker since it's wet. Don't worry about it.

5. Let sit 10 minutes (follow the instructions).

6. Apply the B chemical. Wait about 4 hours (follow the instructions). The piece should lighten as it dries.

7. Wash the piece well with vinegar and water (50-50) to stop the reaction.

8. Leave to dry overnight.

9. You can repeat the bleaching if desired.

10. You'll have to refinish the piece as the grain will be lifted by all the chemicals. Sand normally (Start with 120, finish with 220 or as desired).

After the bleaching the wood is probably a different color than when you started. If this is one piece out of many matching pieces, my experience is that the same original stain won't look quite right (It looks unnatural, has less range and depth of color) It may be better in the long run to start over.

Answer 2

The Minwax website says to apply another coat of stain on top of that and then once it softens
up the dried stain just wipe it off like you normally would. I'm currently having the exact same problem. But I think this makes sense so thats what I'm going to try.

If the mineral spirits don't work out, two options would be to strip the piece, or to sand off the finish.

Stripping is always messy, but it would be easy going on a freshly applied finish. You would then have to re-sand for the new stain. I prefer the methylene chloride strippers. If you use one of them, read and follow the precautions on the label.

Going right to sanding would also work because stain doesn't really penetrate very far at all in the wood. However, you would have to allow the stain dry completely before sanding or you will gum up your sandpaper quickly. If you put the stain on really thick this may take a while and make the stripping option more appealing.

The size and shape of the piece of furniture would also be something to consider when deciding which of these would be easiest.
