When it comes to using an onion to clean your grill, the steps to success are simple. Dan Cooper, Head Grill Master at weber explains that you should use stick half a raw onion (cut side down) on the end of your BBQ fork or tong \u2013 then scrub the grates back and forth until clean. It is best to complete this when the grill is still warm \u2013 to maximize success.\u00a0 The heat paired with the\u00a0natural antibacterial properties of the onion will break down any stubborn char or sticky sauce. Remember: The grates should be hot, so use a fork or a pair of tongs to hold the onion . And if food is really stuck, try using a natural acid, like lemon juice or white wine vinegar, to expedite the process.<\/p>\n
