My brother went on vacation and my mom didn't let him take his favorite Broncos hat with him (So he wouldn't lose it) Then while he was gone, she took down these old shelfs in his room for a surpise… and guess what… one of them had a rusted end and it ended up sitting on his hat for about 3 weeks. Now there is this huge rust stain on it and he's comming back really soon.
Everyone is paniced and well, if you have any idea. besides bleach which we already tried… all it did was slightly and I mean slightly lighten the stain.
Thanks in advance
