Step 1: Turn off the stove.

Make sure the cooktop is set to off and is completely cool to the touch. Using a dishcloth or paper towel, gently wipe any loose debris or liquid from the surface. Do not attempt to remove or scrape a difficult-to-remove trough. Leave the stubborn residue to the diligent household cleaners you’ll prepare later.
Step 2: Soak the rags in warm, soapy water.

Put on rubber gloves when preparing the cleaning solution so you don’t scale your hands. Fill a large bowl, bucket, or kitchen sink with warm tap water. To warm water, add 1 to 2 tablespoons of dishwashing liquid. Mix dishwashing liquid with water until the solution is frothy. Submerge the rag in a bowl, bucket, or sink, and allow it to soak up the warm, soapy water.
Step 3: Cover the cooktop with baking soda and hot rags.

Sprinkle 1 cup of baking soda on the surface of the cooktop. Remove the rag from the cleaning solution and squeeze out half of the excess moisture. The rag should be wet but not dripping. Set the remaining cleaning solution aside, but do not discard it. Cover the entire cooktop with rags, and let them sit for 15 to 30 minutes to allow the baking soda to settle into the debris on the cooktop. Wet rags will create a moist environment that will prevent the baking soda from drying out on the cooktop.
Step 4: Clean the cooktop with baking soda.

Lift the rag off the cooktop and dip it into the cleaning solution again. Remove the rag and squeeze out half of the excess water again.

Finish by gently wiping the rag across the entire cooktop using small, circular motions. The rag and baking soda will work together as a gentle scrub, removing and sliding away any debris without damaging the cooktop’s delicate surface. Now that the cleaning solution has done its job, you can pour the rest down the drain.
Step 5: Shine and polish the glass.

Soak a clean dish sponge in cold water, and gently squeeze out excess water. Wipe the non-stick side of the sponge over the cooktop to clean off any lingering debris or baking soda. When the cooktop is free of residue, use a microfiber cloth to buff the cooktop and give it a sophisticated polish. Work a vinegar spritz into the fabric for a more shiny, streak-free shine.
Going forward, aim to wipe down your glass cooktop after each use rather than at longer intervals. This will save you the time and effort of a deep clean, and preserve your cooktop’s spotless finish all year long.
