I want to donate old work shirts, but I don't want people to be mistaken for employees there. How do I remove the logos? - eviltoast

I have a lot of tshirts from companies I used to work for, but I don’t wear them anymore. I was going to give them away, but I’m worried random people wearing work uniforms might cause problems down the line. Some are construction companies, which I’m not too worried about, but the retail shirts are my concern. Is there a way to remove the text on them so they’re just regular solid colored shirts? I want to say the logos are screenprinted but I don’t think they were, and I can’t remember the name of any other printing processes that aren’t just stitching them in.
