Hello, I’m looking for a thorough cleaning of my oven. It’s a standard freestanding model in a UK kitchen and hasn’t been cleaned in a few months. I’d like the interior racks, trays, door, and seals cleaned, with all grease and burnt-on residue removed. Please use safe, non-abrasive cleaners suitable for enamel surfaces. I’d prefer a flexible time window this week, and I can provide access through the back door. If you offer eco-friendly cleaning options, I’m interested. Please confirm estimated duration and any preparation I should do beforehand.
