Hey there.I am new on here and at the moment I am in the middle of making a comic book cake.after all my work drawing characters and colouring them in ,I spilled brown colour onto the white of the `comic` book.I don't want to start all over again but don't know how to get rid of it.All advice would be very welcome.Thaks in advance

Is it a lot? When I get color on fondant, I take a paintbrush dipped in vinegar and paint it off. 

Not being there, I can't say this will work, but I have many times taken a damp paper towel and cleaned colors off of fondant. It's kind of surprising that you can do this, but it sometimes works fine. I don't mean you wipe it off like the kitchen counter - I'm talking about a very delicate process. And of course using as little water as possible. It leave a we place on the fondant, but as long as you've used barely anywater and haven't damaged the texture, it will dry just fine
 

Try cleaning it off with some vodka.

thanks for the help.th vodka was great:):)
