Dior women’s D-Connect 'Reflective sneakers

I’ve always kept these in the box if I wasn’t wearing them. I’ve only wiped with a wet paper towel when I was cleaning them. I don’t know how to properly take care of white shoes and have always been scared to do a deeper wash on them, but they can use it. The white material is starting to have these light yellow stains. Definitely need to be refreshed. And the bottoms have some scuff marks. Bought on the Dior website. Comes with original packaging and extra unworn shoe laces.
