Hello mmcjrrrj,
Welcome to Mrs. Clean! I'm so sorry for the delay in responding to you, but I was researching your issue.
You have just encountered what every diy (do it yourself) home improvement project person discovers.
Always wear old clothes when painting or staining as it is almost impossible to remove these products from clothing, and it may even take days to remove a product from your skin, until it just wears off.
I would start by trying one of the several wood stain removers and/or paint removers/paint thinners available and gently soak the stains for 24 hours then wash in a gentle cycle in cold water. Do not dry the clothing in the clothes dryer as the heat from the dryer will permanently set the stain.
The key items to remember are:
1. Stains come out easiest if worked on right away.
2. Never dry the garment in the clothes dryer until the stain is permanently removed.
3. Be gentle when working with the stain or you risk fraying the fabric.
4. You can try several products on the stain as long as you rinse completely in COLD water in between each application.
I DO hate to be "beat" by a stain, but I suspect just by the nature of the type of stain which may contain not only a heavy dye but also oil and/or latex this problem may have just turned those articles of clothing into your new set of "cleaning/repair" project clothes.
Please let me know what you discover and or if any item helps you out.
Good Luck!
