Q300 Left Grate Deteriorates Faster Than Right Grate

[KMartinK]

Any ideas on why the left grate deteriorates and rusts much sooner than the right grate? Maybe the burner is too hot on that side of the grill? This is the second set where this has happened. Both were the Weber replacement grates.

I am going to buy a new set of grates, this time I am going to try aftermarket grates, and am wondering if the burner should be replaced as well.

I doubt it's got a problem. Likely it's the side you cook on more. Those Q's are pretty reliable. Very simple. If you keep it cleaned it works perfectly. I'd pull the burner and, get a good really stiff wire brush (like a welder's brush) and brush the hell outta the little ports, wash it out with some "BrakeKleen" and then let it dry.

How old is it, you got any pics?
What I mean is they are porcelain enameled cast iron grates and they should last for awhile.

Either make sure you grill on both sides of the grill evenly or simply swap the two halves around every so often.

The grates are Weber porcelain enameled grates put into service September 2017. After the first year or two, I could see the left side was rusting faster than the right side. I thought maybe excessive heat on one side was burning off seasoning on the one side.

Supposed to be a 5 yr warranty on no rust / burn thru on grates.

Your grill is fine. Just clean it
