“I left a pan on a high flame, and now there’s a black ring on my glass stovetop that won’t come off.”

The fix: Rub the stain with a silicone spatula; small circular motions will loosen debris and fade the color, says Meg Roberts, the president of Molly Maid, a nationwide cleaning service. Then make a paste with 4 tablespoons of baking soda plus a little water and spread it on the stain. Place a warm damp rag on top and let it sit for 30 minutes. Wipe the area clean. If the stain persists, make another paste using 4 tablespoons of baking soda and 1 tablespoon of distilled vinegar. Let the mixture sit for about a minute on the stain, scrub it in with a microfiber cloth, then remove the residue with a wet cloth. The next time you clean the stove, apply a glass-cooktop cleaner (such as Cerama bryte cooktop cleaner; $12, acehardware.com) to the stovetop, then polish with a paper towel, says Bridgid Blocker, the test-kitchen manager for GE appliances.
