Using this oven shelf side rack bushing kit is easy. First, take out the old clips from your oven's side rack. Then, simply attach the new front and back clips from the kit to the corresponding positions on the rack. Make sure they fit snugly. When it comes to maintenance, keep the clips clean. You can use a mild soap and water solution to wipe them down occasionally. As for precautions, always double - check your oven model before purchasing to ensure compatibility.
