When it comes to using natural ingredients to help you clean around the house, you may already be familiar with the benefits of vinegar, baking soda, and lemon to bust stains and kill bacteria. However, for degreasing your grill, your best bet might be to use an onion. Onions have naturally acidic properties, which can be incredibly useful when you are trying to break down the hard-to-remove fat, char, and food remnants from the last time you fired up your barbeque, according to Southern Living.
For best results, turn your barbeque to a high temperature first. This will help to burn away any of the previous food bits, plus melt any leftover grease. Then take a large onion — it doesn’t matter what kind — and cut it in half. With a pair of cooking tongs or a grilling fork, grab or stab the back of the onion and rub it along the hot grill with the sliced part facing the grill. The immense heat will help to get those onion juices flowing, which will start to break up the grease remaining on the cooking surface of your barbeque. Once you have finished, you should be left with a nice clean grill ready for you to use. The leftover onion can then be tossed into the composter once it has been used.
