Spray more solution on spots that are particularly crusty. Then, step back and allow the sprayed grates to sit for 5 to 10 minutes.

It will also kill any potentially harmful germs left behind by raw meat, leaving your cooking surface both cleaner and safer.
If you have a grill brush, you can use it instead of a foil ball. However, many grill users prefer using aluminum foil because it is less likely to scratch the grates or shed potentially harmful metal wires on the grill. [3] X Research source
Any congealed oil and grease should loosen easily after being soaked in vinegar. When you’re done scrubbing the surface of the grates, flip them over and scrub the back sides as well.
The mixture will begin to froth almost immediately. Remove the grates from your grill while they’re cool enough to touch, and place them nearby so you can put them in the bag as soon as possible. Take care to protect your eyes from the vinegar– it can be a serious irritant. If any foam or liquid splashes on you, make sure to wash the affected area thoroughly. [5] X Research source
Overnight soaking is ideal for stubborn, crusty grill residue that may not soften within a few minutes of spraying it with vinegar alone. If your grill grates have significant oil and grease buildup– or if you simply wish to reduce the difficulty of scrubbing them clean– consider soaking the grates overnight instead of simply spraying and scrubbing.

The residue should come loose easily, but if it doesn’t, scrub it away with a large ball of crumpled-up aluminum foil. Scrubbing should be substantially easier than it was before the grates were soaked.
