How to Refinish Burner Grates

Updated February 21, 2017

Burner grates literally support all of our hob cooking efforts, and they can suffer from even the most successful endeavours. Grates suffer through spills, overflows, burns and other cooking troubles; it goes without saying that they need care and protection. A thorough cleaning, followed by a new coat of protective paint, will refinish your burner grates and keep your stove looking its best.

Remove the burner grates from your stove. Place each burner in its own sealable bag or container.

Add 1 cup of ammonia to each bag or container. Add enough water to cover the burner as it sits flat against your table or counter. Seal the containers.

Allow the grates to soak in the ammonia/water mixture overnight; this cleaning mixture will dissolve rust, grime, food build-up and other contaminants.

Remove the grates and rinse them in clean warm water to wash away ammonia and loosened contaminants. Scrub with a non-metallic scouring pad to remove any remaining contaminants.

Thoroughly dry the grates to prevent rust build-up.

Coat each burner grate using the paintbrush and the temperature-resistant paint. Follow product instructions regarding application, as some products might require multiple coats or have varying drying times.

Allow the paint to dry completely before returning the grates to the hob.


If you have a self-cleaning oven, consider placing the burner grates in the oven while it cleans to remove built-up dirt and food. Only use ammonia in a well-ventilated area, as the fumes are toxic if inhaled in large amounts. Find temperature-resistant paints at hardware and home-improvement stores.


Some burner grates are nickel-plated, and only a professional should restore nickel plating. However, you can cover such plating with temperature-resistant paint if you do not wish to consult a professional.
