Cooking cavities
Count the oven compartments and identify a separate grill where present. Show the floor, sides and other safely visible surfaces in photographs. Mention specialist liners, existing enamel damage and any operating fault. Cleaning suitable cooking residue is different from repairing a coating or diagnosing a heating problem.
Racks and accessories
List racks, side supports and trays included in the request. Their coatings may have different care instructions from the oven cavity. Explain heavy residue, corrosion or warped parts. Do not begin treating accessories with an unfamiliar strong product before the appointment; appropriate care needs to account for the complete item.
Door glass and accessible fittings
Show where the marks are, including any residue apparently between glass panels. Internal access depends on the model, fittings and condition. Dismantling a door is not an automatic part of every clean. Cracked glass, a loose hinge or a damaged seal should be identified as defects rather than described as ordinary dirt.
Hob or extractor additions
Name extra cooking-area work separately, with the hob type and photographs of extractor parts where relevant. Burners, coated surfaces and filters may have their own restrictions. Adding them changes the appointment from an oven-only enquiry, so the quotation and preparation should make that difference clear before you book.
