Silk plants stained with algae

[Chels10117]

Hello. I recently noticed algae growing on my silk plants. Only a few of them and it only shows up on the lighter colored ones. I thought I could scrub it off but it didn't come off. I tried vinegar and that didn't work either. I just scrubbed it in vinegar. Has anyone had this happen to them how do you get it off? Thanks!

Looks like I need to keep my tank lights off longer...

Should I try a solution of bleach and water? Or is that too risky?
