The Dirty Truth About Makeup - Oil Change Debate Marketplace : Season 45 Episode 18

What’s lurking on all those free make-up samples? We swab testers from Sephora, Shoppers Drug Mart, Mac and Body Shop. And we ask the ultimate question: Can spraying them with alcohol kill mould and bacteria like staphylococcus aureas? And how often should you change your car engine oil? Depends who you ask. In a hidden camera investigation, we test what you’re told at the dealership and then actually test your engine oil in a lab to see who’s right.
