How To Clean Gas Grill Burner Tube

Now that you know what you need to clean the gas grill burner tube, let’s dive into the process.

Things To Do Prior To Cleaning Gas Grill Burnet Tube

Before jumping to clean the burner tube, there are some tasks you need to do. First of all, turn your grill off. There are lots of cases where amateurs tried to clean the tube while the grill was on. The result was an accident. You don’t want that to happen. Do you?

Also, disconnect the tank. You don’t want gas flowing out while you work. One spark can lead to a massive explosion.  Also, the pungent smell of the gas can make you feel ill. Remove the cooking grates and bars. Now that you got these out of the way, let’s get to cleaning.

Cleaning The Inside Of The Tube

After you remove the burners, you can see the inside of the tube as clearly as daylight. Take the bottle brush and insert it into the tube. Try cleaning every debris and stain in each part. Don’t hesitate to apply more pressure to rougher stains. You can also try to use a burner-clearing rod to reach the deep points.

One popular way of cleaning the inside is blowing the dust out. We have all tried it. There’s no shame in admitting it. While there are some perks, the dust can easily get in your eye. Therefore, put on safety goggles before trying them.

Cleaning The Outside

Now that you’re done with the inside, let’s focus on the outside. Take the brush and start scrubbing on the outer parts of the burner. The outer parts get exposed to heat and dust. Thus, they get dirty pretty quickly and start to rust.

Try not to use a rough brush with sharp ends. They will do more harm than good. A rough brush will scratch the surface of the burner. A soft nylon brush is more than enough. They won’t damage the burner.

You will come across stains that just won’t go away. For these, put some drops of degreaser on your brush and start wiping it. We can assure you after a couple of swipes, they will vanish.

Unblocking The Blocked Holes

You will see a lot of ports in a burner. These ports are of different shapes. Some are square and rectangular while others are circular. When they get dirty, you will notice the shapes appear deformed. This means dust has blocked the ports.

When we’ve mentioned toothpick, you must’ve laughed. You might be thinking what can a toothpick do? Well, this is where the toothpick comes in. Take one end of the toothpick and clear out all the dust. You don’t need to apply too much pressure.

The toothpick has a pointy edge, so it will easily clear the dust. Be aware. Don’t make the holes too big while cleaning them. This happens way too frequently. Bigger holes mean the gas will leak, and the grill won’t function properly. Gently clean the ports while maintaining their original shape.

Reassembling The Grill

After all the hard work, it’s time to reassemble. Put the cooking grates and bars in their original place. Make sure you adjust them properly. In case you’re having trouble, check out the manual of the burner. It will guide you through the whole process. Then connect the propane tank and you’re good to go. It wasn’t that hard. Was it?

Things Not To Do

Always make sure you are cleaning the tube in an upside-downside pattern. This is much more effective. Do not try to clean side to side as it will most likely block the holes or burner ports. Never use bleach or similar caustic products as it is very dangerous around heat.
