It’s BBQ time! That means our grills get a workout. Keep yours clean and ready to cook by spearing half an onion with a metal grill fork, pour a little bit of cooking oil on the outside of it and use to scrub the grease and grime off a still warm grill. The allicin in the onion, a natural antimicrobial, as well as other enzymes, will banish the gunk on your grill. The cooking oil offers a layer of non-stick protection for your next grilling experience.
