How to Clean a Stovetop and Cast Iron Stove Grates

Step by step

1
Let the cooktop cool completely
Turn off all burners and wait until the grates, caps and surface are cool to the touch.

Why: Wiping hot porcelain with a damp cloth can crack or chip it, and cleaners work safely only on a cool surface.
2
Soak and scrub the grates
Lift off the burner grates and wash them in hot, soapy water. Let heavily soiled grates soak for a while, then scrub burned-on food with a plastic scouring pad. Rinse and dry them thoroughly.

Why: Hot detergent water softens grease and baked-on food. A plastic pad removes it without scratching the enamel coating, and drying prevents rust on any bare iron.
3
Clean burner caps and heads
Wash the burner caps in hot, soapy water, scrubbing with a plastic pad if needed. Wipe the burner heads, and clear stuck food from the ports with a plastic-bristled brush. Let them dry fully before reassembling.

Why: Spillovers clog burner heads. Steel wool or metal pads leave fibers that clog the openings further.
4
Wipe the cooktop surface
Wipe the porcelain rangetop with a soft cloth and soap and water, or a 50/50 mix of vinegar and water for grease, as one appliance maker suggests. Rinse with a clean damp cloth and dry.

Why: Gas cooktops are porcelain enamel, which abrasive cleansers, oven cleaner and steel wool scratch or damage.
5
Wash the knobs and reassemble
Turn the knobs to OFF and pull them off their stems, wash them in hot, soapy water and dry them. Put them back in the OFF position, then refit dry burner parts and grates.

Why: The maker's instructions say to put them back in the OFF position. Reassembling only dry parts avoids trapping water in the burners.

What a stovetop is made of, and what that rules out

Gas rangetops are usually porcelain enamel, with cast iron grates (often enamel-coated) and aluminum or brass burner heads. Electric smoothtops and induction cooktops are ceramic glass, and coil ranges have porcelain drip bowls under the elements.

Those materials set the rules. Porcelain and ceramic glass scratch with abrasive cleansers and steel wool. Acidic spills such as tomato sauce can discolor porcelain, so the American Cleaning Institute advises wiping them up promptly. Burner ports clog with steel-wool fibers. One appliance maker says not to use bleach or rust removers on burner grates. And the American Cleaning Institute warns that ammonia or bleach cleaners may discolor ceramic glass.

Cleaning cast iron stove grates

Cast iron grates on gas stoves are often enamel-coated, and the appliance maker's method is hot soapy water and a plastic scouring pad, not steel wool. For heavy buildup, soak them longer in hot water with dish soap before scrubbing, and repeat rather than switching to harsh tools or chemicals.

Two options depend on your stove: some self-cleaning ovens allow the grates to be left in during a self-clean cycle, and some grates are dishwasher-safe. Check your use and care manual first; one maker specifically says to check whether racks and grates can stay in for self-clean. Bare, uncoated cast iron behaves more like a skillet: dry it promptly so it doesn't rust (see cast iron for how seasoning works).

How often: wipe spills from the cooled cooktop after each use, and wash grates and caps whenever they're visibly soiled.

By situation

Glass and ceramic cooktops

Use a ceramic cooktop cleaner with a non-scratch pad, or a paste of baking soda and water, then rinse and dry. For burned-on food, let the surface cool completely, hold a single-edge razor scraper at about a 45° angle and scrape, then polish with a few drops of cooktop cleaner. Use clean cloths: soiled ones can leave a film.

Induction cooktops

Clean them the same way as glass cooktops: ceramic cooktop cleaner, a non-scratch pad, and the razor scraper for burned-on residue once cool.

Coil burners and drip bowls

Remove the drip bowls once cool and soak them in hot water with dish detergent, then scrub with a liquid abrasive or soap pad. The American Cleaning Institute notes porcelain drip bowls can go in the dishwasher, and that for difficult soil you can use oven cleaner on the removed bowls, outdoors on newspaper, per the label. Don't line drip bowls with aluminum foil.

Burned-on grease on the grates

Give the grates a longer soak in hot, soapy water and scrub again with a plastic pad. Several rounds are normal for heavy buildup. Avoid oven cleaner on the rangetop itself, and check your manual before using it or a self-clean cycle on the grates.

Tomato sauce and other acidic spills

Once the surface is cool enough to touch safely, wipe them up promptly with a dry cloth. Acids left on porcelain can discolor it.

What not to do

Don't use abrasive cleansers, oven cleaner or steel wool on a gas rangetop. They damage the porcelain enamel.
Don't use bleach or rust removers on burner grates. One appliance maker specifically prohibits them on burner grates.
Don't use steel wool or metal pads on burner heads. Fibers clog the burner openings.
Don't use ammonia or bleach cleaners on a glass cooktop. They may discolor the ceramic glass.
Don't wipe a hot porcelain surface with a damp cloth. The sudden temperature change can crack or chip it.

Other methods that work

Vinegar and water for grease

A 50/50 solution of white vinegar and water on a soft cloth, wiped on and rinsed off, is one appliance maker's option for grease on gas tops. More on white vinegar.

Caution: Keep it off natural stone counters around the range, and never mix it with bleach.

Baking soda paste

A paste of baking soda and water on a non-scratch pad, for glass cooktops and stubborn spots.

Caution: It's mildly abrasive; use gentle pressure.

Stain still there?

A burner lights unevenly after cleaning

The ports may still be blocked, or the parts damp or not seated correctly. Let them dry fully, clear the ports with a plastic-bristled brush, and seat the cap properly. If it persists, check the manual or call for service.

Grates still look grimy after scrubbing

Soak them longer in hot, soapy water and scrub again with a plastic pad. Check the manual to see whether your grates can go in the dishwasher or self-clean cycle.

The glass cooktop has a hazy film

Usually residue from a soiled cloth or cleaner. Polish with ceramic cooktop cleaner and a clean, dry cloth.

Questions

How do you clean cast iron grates on a gas stove?

Let them cool, wash them in hot, soapy water, scrub burned-on food with a plastic scouring pad, then rinse and dry them thoroughly. Don't use steel wool, bleach or rust removers.

Can you put stove grates in the dishwasher?

Some can; check your range's use and care manual before you try it.

Can you clean stove grates in the self-cleaning oven?

Only if your manual says so. One appliance maker specifically tells owners to check whether grates can stay in during self-clean.

How do you remove burned-on food from a glass cooktop?

Let it cool, scrape with a single-edge razor scraper held at about 45°, then polish with ceramic cooktop cleaner and a non-scratch pad.

Can I use steel wool on my stovetop?

No. It scratches porcelain and glass, and its fibers clog burner ports. Use plastic pads and brushes.
