Stain Left By Tape?

I have had good success with products we can buy; over here (US) they have names such as "Goof Off" and "Goo Gone". You spray it on (or use it as the directions say), and it dissolves the residue; then you launder the fabric. (Great for the residue after a sticker has run through the laundry and the paper came off, but not the sticky....!) If it is a "fine" fabric, I would test the solvent first!

I expect you can find it, if not with the laundry products, in the paint department!

When my kids were small, I'd use Avon Skin so Soft. Worked great and didn't leave a stain.

Men's after shave does a great job and makes items smell good!
