There is so much to love about this premium cleanser from Bar Keepers Friend as it gently yet effectively cleans glass and ceramic cooking surfaces without scratching and it also removes difficult lime and hard water stains. You wont have to worry about burnt on food residue just flip the lid open and squeeze your Cook Top Cleaner onto a wet surface then rub gently with a wet cleaning cloth or sponge. If the stain is stubborn, allow the cleaner to sit for a minute then rub gently and rinse well.
