Hello everyone, kind of new here.
I have just removed a twill number off of an air-knit material. I pulled the stitches and unfortunately there is a bunch of gunk attached.
The jersey that the gunk is on is a rare garment, and it is unfortunate that someone added the number.
I am looking for any tips on removing this stuff without messing up the color. If you have any tips, please let me know. It would be highly appreciated
