How do I remove iron-on letters without damaging the fabric that it is on?
It is really hard and not often possibleto get it all off. I used to work in and then own, a shop where we put on iron on transfers and those iron on letters all the time! sometimes we would make a mistake and we would use a special solvent for getting rid of the glue, but most of the time the outline would still show somewhat, and then we usually put the right letter on it to cover up. I think the solvent was really like many glue removers, like that stuff you can get in stores to remove sticky tape residue or rubber scuff marks on the floor? A name evades me but am thinking like “goo gone”? If you soak the letters/fabric well, then start to peel most of it should come off and rub off the remainder, as much as you can, with a clean white cloth.
