How To Clean Commercial Cast Iron Stove Grates with Soap:

Step 1: Let the Grates Cool Down

Before cleaning, ensure the burners and grates are completely cool. Safety comes first! Once they’ve cooled down, carefully remove the cast iron grates from the stove and place them in an empty sink or tub.

Step 2: Soak the Grates

Fill the sink or tub with hot water, ensuring the grates are fully covered. Now, add a bit of dish soap to the water. Soap is like a superhero that fights grease and stuck-on food. Let the grates hang in soapy water for 10 to 15 minutes. This gives the soap time to work magic and loosen up all the gunk.

Step 3: Scrub Away the Dirt

After the grates have soaked, it’s time to give them a good scrubbing. Grab a soft-bristled brush, pad, or sponge that’s not made of metal – we want to avoid scratching the grates. Start scrubbing away the leftover food bits and grease. Get into all the nooks and crannies to make sure every part gets cleaned up.

Step 4: Rinse and Dry

Once your grates look shiny and dirt-free, it’s time to rinse off the soap. Use warm water to thoroughly rinse each grate until you can’t see any soap residue. After rinsing, dry the grates completely using a clean cloth. We don’t want any moisture sticking around that could lead to rust.

Helpful Tip:

Remember, cast iron grates need some special care. Don’t use rough, metallic scrubbing pads or strong cleaning chemicals like ammonia. These can damage the grates and make them sad.
