To make it easier, I will split this task into few steps.
The below steps show how to clean the entire gas grill, grates, grill box and burners.
It may seem like a complicated task, but in reality it is very simple. It’s an easy and fast method to bring your grill back to a great condition.
How to Clean a Gas Grill - Step by Step
Don’t warm up the grill, we start cleaning with a cold grill.
Prepare the necessary accessories that will make the cleaning easier for you. Most of all, prepare gloves, as it is a messy task and of course the grill brush.
Open the grill’s lid, and then remove all the parts such as the warming rack or grates.
After removing the first elements from above, you’ll get access to the upper chamber of the grill, where further significant elements are located such as burners, aromatizers, burner covers etc.
Remove all of that to get access to the lower part of the grill chamber.
After a longer time, the main chamber of the grill located below the grates gets dirty. It is because during cooking the grease and small pieces of food fall down between the bars of the grates and collect in the main chamber, creating a thicker layer of residue.
Thoroughly clean the bottom of the grill (cook box ), get rid of everything that’s there.
I recommend putting on gloves for this messy task. The grease and food remains collected over time have created a thicker layer of residue by now, which is harder to remove.
The best solution will be a thin plastic spatula and a brush that will make it easier to scrub the dirt off every side inside the grill.
Clean the burners and burner covers.
The burners are the element that is most prone to getting dirty, a burner’s pipe can get clogged which results in smaller flames. Another consequence of a dirty burner are flames of a different color, a clean burner burns blue, whereas a dirty one burns orange.
All of that leads to problems with the grill’s efficiency.
Clogged burners result in problems with getting high temperatures and make an impression of a weaker grill, as they emit a much smaller flame.
Use a steel or nylon brush to gently clean the small holes in the burners’ pipes.
Depending on what grill you own, there are several of those pipes, so try to clean them all. Especially pay attention to the holes so that during cleaning you don’t accidentally clog other holes.
Use a wet sponge for cleaning as well, which is very good at collecting dirt in form of residue. Remember to carefully dry the burners’ pipes after cleaning with a wet sponge.
The next thing you should do is cleaning the burner covers.
You can do it using a wet sponge, thoroughly clean the surfaces off the old residue, then dry them.
Next clean the tray located under the grill, it is the easiest to do by washing it hard with a wet sponge, then wiping with a paper towel.
After cleaning the entire chamber of the grill and all the significant elements located inside the grill and responsible for its proper functioning, you can move on to the next stage.
Put all the clean and dried elements back where they originally were.
Cleaning the food remains and grease.
The best method is to set the burner knobs to the maximum, close the lid and leave the grill on like this for 10-15 minutes. It will allow to reach a high temperature which will burn the food remains and grease on the grates to a significant degree.
After about 10-15 minutes open the grill’s lid and clean the grates using a grill brush.
Clean the grates, it seems like a mega simple task but there are different kinds of grates ( steel, porcelain, cast iron etc ). Each type of grill grates requires a different method of cleaning.
For example, you can’t clean porcelain or cast iron grates using a steel brush, as you would damage the surface which could lead to corrosion. For this task, you have to own a nylon brush that is delicate and doesn’t damage the surface of grates.
It’s a broad topic that I touched in a different article, find out how to clean grill grates using different methods depending on the type of grill grates.
Clean the side shelves and the lid.
Wash the lid using a paper towel and a cleaning agent ( Use a special glass cleaner for porcelain covered lids and a stainless steel cleaner for stainless steel lids ).
You can wash the side shelves using a micro fiber towel or paper towels and a stainless steel cleaner.
That’s it when it comes to gas grills.
Remember to clean the grates after each cooking or before it.
Comprehensive cleaning of burners, burner covers, aromatizers and the entire grill chamber, on the other hand, is enough to be performed 1-2 times a year depending on how often you cook on a grill.
