If your gas grill is located outside, it's subject to some harsh conditions!
Most people tend to take their outdoor gas grill for granted. They don’t spend much time thinking about it at all -- until they’re ready to use it. However, because your grill is outside, it is subject to some pretty harsh conditions like rain, snow, ice, and heat. These can all do a number on your gas grill.
When you are ready to use the grill again in the spring and summer, the impact of those conditions will likely become more apparent to you. At the least, you will need to clean your grill very well before you can use it to prepare food. At worst, you may need to do more than just clean it. You may need to replace parts, check the gas line, or deal with other potential problems.
