Most of the carbon in a domestic oven is not on the cavity walls. It is baked onto the racks, the trays, the fan cover and the inner face of the door glass — the four parts a spray-and-wipe never reaches. Our technicians remove those parts, soak them in a heated, non-caustic tank inside the van, and hand-detail the cavity while they are soaking. We apply this to every Tyldesley visit, including the tighter terraced streets off Tyldesley's Elliott Street and the Astley Green Colliery Museum nearby.
The door is split where the hinge design allows so the sandwiched glass is cleaned on both faces, the seal is checked for splits, and the appliance is rebuilt and function-tested before we leave. Nothing corrosive touches enamel or pyrolytic liners, so there is no chemical smell around food and the oven can be used within the hour.
