505 spray. Help
I used 505 spray to hold polyester shirt to stabilizer. I've used this for years. All was good, no spots, but needed to rinse off washable stabilizer, of course dried them, 5 of them, now a small spot to 3 spots show up on 3 of them. I have tried Shout, another spot remover, and now have Dawn on them, I think they are getting lighter. Worse of all the logo was embroidered on $70 shirts for someone else. I really need help
