Using this 145mm glass top stove chrome trim ring is easy. First, make sure your stove is turned off and cooled down. Then, carefully remove the old trim ring if there is one. Place the new chrome trim ring in position around the small hotplate on your glass top stove. Ensure it fits snugly. When using your stove, avoid using abrasive cleaners on the trim ring as this can scratch the chrome finish. To clean, use a soft cloth and a mild glass cleaner. If the trim ring gets dirty, simply wipe it down regularly to keep it looking shiny. If you notice any damage to the ring, it's best to replace it promptly to maintain the safety and appearance of your stove.
