I have these dyna glo cast iron grill grates. I already had to buy replacements about 6 months ago because they were chipping. They look like they are starting to rust and chip again. Can anyone help explain what is going on here? I clean/brush them down after I grill each time. Do I need to be doing anything else. I don’t normally apply any oil

The are corroding. This will happen with cast iron with high heat and moisture.
Can be limited if you brush them real well to get ride of the gunk and then oil them when done cooking.
Are you sure they are just cast iron and not enameled? It looks like enamel coming off. Any crack or flaw in the enamel can allow the underlying cast iron to rust, which expands and pops off the coating. Happened to my Weber grates after about 8 years.
It’s normal, cheap grill, cheap parts. But the cast iron eventually falls apart over time. Buy stainless grates if you can find them they will last longer.
They’re upside down, for starters.
You’re not cleaning them adequately
Scrape them and brush them with crisco after each use – they’ll last forever
As someone that bought a few dyna products…. it’ll never go away. You’ll replace it and next year it’ll be the same thing. Its chinesium.
Upgraded to a Weber 3 years ago. Not a spec of rust on it after 3 years being covered outside in Wisconsin.
Never will buy dyna or the like again.
The white bits on the grates look like mold growing on grease, so burn it off and/or brush/scrape. If it’s ash, then it’s a non-issue. Iron and stamped steel grates (whether porcelain coated or not) will eventually corrode and rot through. Mine never lasted more than 5 years.
Best answer is stainless rod grates, which won’t ever corrode. I got mine from [grillparts.com](http://grillparts.com) but there are plenty of other retailers which sell the same.
And your heat deflectors are shot. This is another 5 year max consumable part. Replace with stainless steel. Got mine from Amazon (same cost as porcelain steel).
Not getting clean enough. After your done cooking turn up the grill to full heat for about 10 minutes. Then clean with wire brush, close lid and let it go a bit longer then turn it off.
Spalling. They got wet.
This directly from the Amazon page you linked.
*How to Avoid Rust？】(1) Make sure that you scrape your grates after each use; (2) Season them by brushing with oil after each use; (3) Leave the dampers open a bit so that condensation does not collect in the grill; (4) Put the lid back on your grill when it is not in use; (5) Cover the grill when it is not in use; (6) If you need to store your grill for a long period of time, heavily coat them in cooking oil, wrap them in a plastic bag and store in your covered grill*
Go with good heavy duty stainless steel racks! I’ve never looked back or regretted it! Cast iron is for fry pan and Dutch ovens! I’ve spent a small fortune on cast iron racks and tried every tip and trick out there. Not worth it. SS racks for the win!
Get some high grade stainless ones. If you’ve only had those 6 months, then either your cooking a lot at high temp or the environmental conditions in the air where you live has a high salt content or those grates are just garbage from the factory. High grade stainless (T-409) has almost as good a heat retention as cast iron and less maintenance. Not cheap though.
