Grilling outdoors is full of attractions, whether you want to spend a sizzling summer barbecue with friends or a cozy winter cookout with family. However, to ensure that your outdoor grill remains the centerpiece of delicious meals and joyful gatherings year-round, proper maintenance, and cleaning are essential.

In this blog, we'll unveil five cleaning techniques and maintenance tips that will keep your outdoor grill shining and ready for year-round grilling delight.

1: Coat the Surface of the Grill Grate

Seasoning your grill is an age-old technique that not only helps maintain the grill's surface but also imparts an extra layer of flavor to your food. This technique involves applying a layer of oil to the grates and heating them until the oil forms a protective barrier against rust and corrosion.

Step 1. Before turning the grill on, coat the surface of the grate with high-heat cooking oil. Canola oil and peanut oil work well, but you can also use coconut oil or spray-can vegetable oil.

Step 2. Wipe any excess oil off the grate with a paper towel, then turn the grill on high for about 15-20 minutes or until the oil burns or smoke. By the end, the grate should become dark.

You'll notice smoke as the oil burns off. Repeat this process a few times until the grates develop a glossy, dark finish. This coating will help prevent food from sticking to the grates and make them easier to clean after each use.

4) Rinse them off with clean water. After all the components dry completely then reassemble the grill.
