The days are getting longer, which means barbecue season is soon upon us. But first, you might want to give your grill a good cleaning. Not only does a dirty grill attract bacteria that could contaminate your food and make you sick; it also makes a big difference in how the food tastes when you pull it off the grates. (A little char is one thing, but nobody wants a burnt taste on their flank steak.)
A dirty grill is also a dangerous grill, since built-up grease and crusty food bits can lead to an unwanted blaze in your backyard. And then there’s the health of your grill to consider: that same gunky buildup will dramatically shorten the life of your Weber or Char-Broil and diminish its performance day to day. Gas grills rely on clean burners that allow propane to flow freely, and if the hull of a gas or charcoal grill isn’t regularly emptied or cleaned, it’ll rust and break much faster.
If you’re wondering how to really clean and maintain your grill properly so it lasts longer and doesn’t cause any trouble this summer, I’ve outlined some easy steps below. For this article, I used a propane-fueled model to illustrate the best grill-cleaning techniques, but this routine can work for charcoal grills, pellet smokers and kamado grills too.

How often should you clean your grill?
How often you’ll need to clean your grill depends on how often you use it and how dirty it gets when you do. Most experts suggest deep-cleaning your grill at least twice per year, with lighter, maintenance cleaning after each use. If you’re a heavy griller (or not as good with the post-dinner clean), three times per year would be a better cadence. If you’re a seasonal griller, you’ll definitely want to give your grill a good clean before you put it away for winter and likely again in the middle of peak season.
How to properly clean a grill
1. Open up the grill and pull it apart
First, you’ll need to open the grill and remove its various parts. This way, you’ll be able to access the main grill chamber. Typically sitting below the grates, this is where heavy food particles tend to fall and grease drippings land.
Start with a cold grill. Open the hood, remove the grill grates and set them aside. Some propane gas models also have one or multiple metal heat diffusers that rest over the burners. If your grill has them, take those out too.
2. Clean the inside of the grill
A lot of grease and food particles tend to collect inside the grill’s interior, also known as the “grill box.” Use a cheap putty knife (metal or plastic) or an old spatula to scrape the sides of the grill chamber free of as much gunk as you can.
Any thin, flat tool will do. Just make sure it provides a good surface or handle to grip. You also might want to consider getting a pair of work gloves, too, since this is bound to be a dirty job.
On charcoal and wood pellet grills, ash will accumulate within their coal trays and fireboxes. That in turn limits airflow, and ultimately affects cooking performance. And in the case of pellet grills, ash can cause misfiring of the pellet system. Sometimes this situation leads to a precarious over-firing condition when too much fuel ignites at once.
Avoid that by regularly clearing your grill of ash deposits. Just be sure to do so when the ash has cooled completely.
