However, there are still some things you may want to consider doing in order to make sure they last as long as possible.

1. Don’t scrape the BBQ grates

2. Brush your BBQ grates

The easiest and best way to make sure your BBQ grates last as long as possible is to brush them every time you use the grill. Just preheat the grill on high for 15 minutes with the lid closed and then brush the grates clean with a dedicated stainless steel grill brush.

3. No citrus-y soaps

It is not necessary to washing your BBQ grates in the sink. But in any case you find yourself with a reason to do so, avoid using any citrus-based cleaning agents as they can promote corrosion. Instead, soak the BBQ grates in hot water to remove stubborn particles and then gently brush the debris off with a mild dishwashing liquid and soft brushes. Make sure you use a soft cloth or paper towel to thoroughly dry the grates when you’re done. Letting them air-dry can also promote corrosion.

4. Consider the environment

If you live near seas, or anywhere where a body of saltwater is near your BBQ grill, you should consider keeping your BBQ grill covered. We also recommend cleaning your BBQ grill and cooking grates more often as the vapour from saltwater bodies are highly likely to corrode your porcelain enamelled cast iron cooking grates.

Show your beloved BBQ grates a little love and they’ll return the love by cooking you lots of tasty BBQ foods over many years of BBQ parties.
