Plastic scratch remover

Anyone know of a solution to repair dull and scratched plastic? Trying to refresh the sliding tray handle due to dogs climbing in and out.

 

Prep and repaint using SEM satin interior paint. It won’t remove the scratches per se, but it will cover them well.

 

Try a little Mother's Back to Black restore (may cover up as well but not take away scratches). Perhaps try on side or underside of tray first in an area not so "visible"

 

Painting it is the best solution. imho.
