Do you enjoy having a family barbeque every summer? Then you want to have your grill in top shape. If you don’t clean it regularly, the grease and sauces can lead to bacteria. Also, excessive carbon buildup causes the grill to heat unevenly. So, here are the steps for how to clean a grill.
Quick clean: 10-15 minutes
Standard deep clean: 45-60 minutes
Full seasonal clean: 1.5-2 hours
The first step is to get together all your ingredients in a bucket. You can also skip the chemicals and go with natural cleaning products you can find at home, like vinegar. This is better for the environment and doesn’t impact the taste of the food. Plus, you can find affordable cleaning supplies at local retailers, such as Walmart.
Here are a few standard supplies to have on hand:
To clean a grill start by turning it on, closing the lid and letting it rise to maximum temperature. Give it some time for the heat to remove any stuck-on food or grease. Then scrub off all the carbon from the grates with a wire brush. Dip the tool in the bucket of warm soapy water. For a deeper clean, add a mixture of baking soda and vinegar.
Then shut off and disconnect the gas before removing the propane tank. Be sure to let the grill cool completely. The specific process for cleaning depends on the type of grill you have.
Here is the process for each type:
After the appliance has cooled down, remove the grates and bars. Soak them in a bucket of warm and soapy water. This step for cleaning a grill allows you to remove harmful germs, keeping your family safe. Then take off any removable parts, such as burner control knobs and warming racks. This allows for quicker and more convenient cleaning.
If you have tough stains, add baking soda and let them sit for about an hour. Then scrub the parts with a steel wool pad to remove debris. Before placing them back, rinse with your garden hose. You can even use a cup of ammonia, but just rinse it out your grill thoroughly.
With the grates taken out, you can clean the inside of the firebox. Place your empty bucket below the firebox, directly under the grease tray opening. It will catch the water and debris being flushed out.
Use warm water and dish soap to scrub the entire firebox. Then use a putty knife to scrape off any dirt or leftover food crumbs. Next, grab a wet/dry vacuum to remove the loose debris. Once you wash the firebox, rinse it out with your garden hose.
This is an important step for how to clean a grill thoroughly. Scrub the different parts with a wire brush. Create a paste with vinegar and baking soda for any tough stains. Once you’re down washing, rinse the surfaces to prevent rusting.
Also, check the porcelain grates for chips. To clean any chips or rust, coat them with oil to form a protective film. Also, inspect your burner for any signs of corrosion or blocked holes. Then take a wire brush across the gaps of your burner tubes. Make sure to clean the inside of the pipes too.
Once the dirt is removed, fill a bucket with clean water and dish soap. Then scrub down the outside of the grill with a sponge. Keep in mind that steel wool or metal sponges may cause scratches. It’s best to only use steel wool when cleaning the cast iron grates.
So, try not to use them on a finished surface. Look for a non-scratch scrubber from Amazon. After cleaning the outside, use a microfiber towel to wipe down and dry the area. This helps prevent mold or bacteria build-up.
Use a stainless-steel cleaner to remove heavy grease or food buildup. Spray the cleaner, wait a few minutes and then wipe the surface with a dry cloth. Use straight vinegar for any tough oil spots and wipe down with the water.
If these stains remain, use a stronger grease-cutting tool. Once the grill is thoroughly washed and dried, put back the removed parts. Place the burner tubes back in the proper position and wipe them down with a thin coat of vegetable oil. Then complete these final steps:
When using and cleaning your grill, there’s a good chance you run into some problems aside from the normal dirtiness of a grill. Here are some common problems and their solutions for when you encounter them:
Solution: Sand with fine steel wool, coat with cooking oil
Solution: Use baking soda paste, let sit 15 minutes
Solution: Clean grease trap more frequently
Solution: Check and clean burner tubes
Yes, but not on the cooking grates or any surface that will touch food. A better alternative would be dedicated grill degreasers or natural solutions like baking soda paste and vinegar that are food-safe.
Safe uses:
Never use on:
Yes, but not right away. It will only be safe after properly rinsing and drying your grill. Be sure to wipe all surfaces with clean water 2-3 times, let it air dry for at least 30 minutes, and heat the grill to at least 500°F for 15 minutes before cooking. If you smell chemical fumes during burn-off, continue heating and ventilating.
Several effective alternatives exist that are often safer than wire brushes:
As summer gets closer, it’s time to give your grill that sparkle and shine. Keeping up with regular maintenance ensures your family is safe from harmful bacteria. So, follow these steps to clean your grill the right way.
