Birnie H Naperville , IL June 23, 2017 Appliance: Model GE XL44 Gray burner caps were constantly stained and had to be cleaned. Bought black ones to replace them. They look great and match the black burner grates and pans I had bought previously. Good service from you. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
