I finally got around to working on the sun visor that was laden with mascara or eye pencil. Thank you for all your suggestions!
I used Shout carpet cleaner on it (comes in a yellow spray bottle). I sprayed it on and immediately blotted with a dry terry towel. I then blotted again with a slightly damp terry towel. It worked like a charm! I had to do a repeat on one spot but it took it right out. I then wiped the visor with the damp cloth. Honda must make the roof liner and visor covers out of a synthetic material on the Accord. I'm relieved it's gone.
Maybe I fret over my vehicles too much.
