If you are preparing for summer cookouts and long, warm nights in your backyard or your outdoor dining area, there is another important thing you should take into account: cleaning your gas grill. Whether you’re a novice griller or a BBQ pitmaster, keeping your grill clean is an important part of creating a good meal

There is perhaps no finer way to spend a summer evening than grilling and eating perfectly juicy steaks with your friends and family. In this sense, all gas grills often have a long lifespan, but that can be shortened if you don’t clean and maintain yours regularly

Maintaining your gas grill after each use cuts down on the time to make your grill shine, but even if you haven’t cleaned your grill all season, a little effort will get it cooking like new again. Luckily, maintenance and cleaning don’t take too much effort. Read on to find out how to keep your gas grill functioning smoothly and belching meat-searing heat.

Why cleaning your gas grill?

Firstly because outdoor fun is only possible with a grill that is cleaned and maintained throughout the year. There are simple cleaning steps that you can do after every time you grill, along with deeper, semi-annual cleaning steps to keep your grill working its best for years to come. An outdoor grill that is kept clean and maintained will stay in good working order and will ensure that the food you cook on always tastes great.

When should you clean your grill?

How often you clean your grill depends on how much you use it. In general, once a month scrub-down of the grates, bars, and grease management system is a good idea. If you notice your grill isn’t heating up as high as usual, it may be a revealing sign it’s overdue for a cleaning.

Did you know? Too much grease and schmutz in the grill can hinder the effectiveness of the grill and the quality of the food you’re cooking. You don’t want to completely clean off this grease because it can add flavour to your meat, but bear in mind that a hefty build-up of grease can hamper the airflow inside your grill. Always make sure your cleaning leaves just a light layer of barbecue drippings.

We advise you to brush your grill grates after every use. In this sense,  you should give your grill a thorough cleaning twice a year, which helps it cook better and last longer. The basic process is the same for gas or charcoal grills; charcoal grills just have fewer parts.
