Just did this the other day, i had white wax residue around the door handles and mirrors. I used Meguiar's Natural Shine Vinyl & Rubber Protectant
http://www.meguiars.com/product_showroom/showproducts_template.cfm?SrcLine=CI It worked GREAT, it also got rid of the oxydation on the side windshield strips

.
Can be bought at any local Auto store.
Cheers.
