Hello, rookie question here. Just posting to get some information on a recent job I did. I was cleaning the front of a store using %12.5 bleach. There was a vinyl banner with yellow lettering hanging on the store front and the yellow lettering turned into white/grey lettering. I've been using bleach a few years now but have never run into this. I thought vinyl would be unaffected by bleach? only the yellow lettering turned the rest of the banner was fine. I am trying to determine how to prevent this in the future. Am I wrong in thinking vinyl isn't affected by bleach? Thanks in advance for any comments!
Ps. (full disclosure) I did use a very hot (full 12.5%) for some very dark spots on by the sign. I usually try to avoid that but the marks just weren't lightening up.
