I'm looking for a reliable cleaner to give my oven a deep clean. The oven has light grease buildup and some baked-on stains from regular use. I prefer someone who uses safe, non-toxic cleaning products and can handle both the interior oven cavity and the door, plus the racks. The job should include wiping down the exterior control panel and cleaning the glass door to a clear shine. I’d like to schedule a visit on a weekday morning, with a view to finishing within a couple of hours. Please provide an approximate quote and any preparation tips (e.g., removing racks).
