Summer is undeniably the season of grilling. But during fall, winter, and even spring, your grill tends to sit and rust. Sad, we know. So when you open up your BBQ grill to start the grilling season, you probably found what we did: grimy, gross, caked-on grills.

Your first game plan is probably to go to town on your grills with steel wool or a bristle brush. But after 10 minutes with a wire brush, you probably realized you need another approach for getting your grills shining again. Well, we are here to tell you that people across the internet had the most success with the method below.

All you need is some household ammonia, a garbage bag, and a rubber band or some kind of tie to keep it all together. This is a quick, effective method that doesn’t require any serious elbow grease!


  • Ammonia
  • Garbage Bag
  • Rubber band or some type of tie


1. Pour a cup of ammonia into a garbage bag.

2. Place BBQ grills inside a garbage bag and seal tight with string, rubber band or some sort of tie. Make sure it’s tied tight for two reasons: A. it’s the vapors from the ammonia that clean your grill and B. It’s better for the environment to not have ammonia leaking into lawn/soil.

3. Place your bag in the sun and let sit there until the following day. The heat from the sun will help speed up the process of the ammonia.

4. The following day take your grills out and rinse with water in a garage sink if you have one or any other sink as long as you open windows and it’s well ventilated.

Safety Precautions

When working with ammonia always use gloves and eye goggles. Make sure you are in a well-ventilated space so the fumes don’t cause dizziness or other negative health defects. For disposal, you can wash down sink with plenty of water. You may also check with your local poison control board for disposal options.

Don’t worry about getting the entire grill covered in ammonia, no need to waste the product! As long as the garbage bag is tightly closed, the fumes from the chemical will be enough to strip down the grill of all the grime and caked on food. That being said, make sure you adhere to those safety precautions above because ammonia is an extremely strong and can be harmful if used incorrectly.
