【Essential Cleaning Tips for Lazy People】① Use salt to clean glassware. Gently rub glassware with your fingers dipped in salt to quickly restore its shine. ② Clean cutting boards with vinegar. Mix 2 tablespoons of vinegar with 200 ml of warm water, pour it onto the cutting board, and let it sit for 15 minutes; the black grime and odor will disappear. ③ Use flour to remove grease. Flour absorbs grease, making it perfect for dealing with grease. ④ Use fruit peels to eliminate black grime. For black grime on pots and kettles, scrub with water boiled with lemon peels.
