Vinyl stains / yellowed
 

Hey,
I have white interior in my 79 Camaro. In some spots (eg at the door where it touches the weatherstrip of the A pillar)the vinyl yellowed.

I already searched online and tried baking soda and lemon juice....I even took my courage in both hands and tried the bleach technique...both didn't work.

I got to say that the baking soda - lemon juice method is pretty good to clean the texture of the vinyl.

Does anyone know a method that might work or a special cleaner that helps with the yellowed spots?
