I parked my car in some parking lot and the security mistakenly placed a sticker in it warning that it may get towed even though I did have the authorization to park my park at that location.

It will take some significant effort to remove it and clean its mark, and is likely to require purchasing products and/or tools for it.
This made me wonder: If someone erroneously places a sticker on my car, are they obliged to remove it and, if necessary, clean any residual mark left by it? I'm interested in Washington state, in the United States.
The sticker left marks despite trying to carefully remove it:
