I'm looking for a reliable cleaner to do a thorough cleaning of my oven. It’s a standard household oven, not a self-cleaning model, and it has some baked-on grease from cooking experiments. I’d like the racks, grills, glass door, and interior walls scrubbed and deodorized. Please bring appropriate non-abrasive cleaners and microfiber cloths. I’m hoping for a careful job that won’t scratch surfaces, and I’d appreciate a brief before-and-after check and any useful tips for maintaining the oven between cleanings.
