If you find the stain and it has already dried, you can still attempt to wash it out. But it might not be as effective.
If you must rub the stain (in order to clean it, for example), try to rub the stained part of the cloth against itself as best you can, leaving the unstained part alone.
Rubber gloves work best for this kind of protection.
You might try testing on the inside hem or and inner part of a pocket. This is a good idea if you plan on using bleach or mineral spirits to clean the wood stain.
You can try using a Clorox Bleach Pen or a Tide To Go pen.
You can purchase a can of mineral spirits at any home improvement store.
Be sure to place a thick layer of paper towels underneath the stain before you apply the acetone. This will help soak up the acetone and the stain from underneath, and protect the surface of whatever you’re using to clean on top of.
Be sure to keep the bucket out of the way so that it doesn’t get knocked over. You might consider placing it inside your bathtub or shower while you’re waiting for it to soak.
Set the washing machine settings for a small load.
You can even add 3⁄4 c (180 mL) of bleach to help remove the stain. But make sure to use color-safe bleach if the stained item is any color other than white.
If you must let the garment dry before you continue tackling the stain, let it air dry only.
