Clean the cavity with a non-caustic cleaner and a genuine thirty minute dwell, then treat the fascia and the hob as part of the same job, because a freestanding Emilia is one appliance. Doors at 900mm and wider are a two-person lift.
Emilia sells Italian freestanding ranges into Australia at 900mm and wider, and they are almost always bought deliberately rather than inherited with a house.
A chosen appliance, and what that changes
Most of the brands in this series arrive with a property. An Emilia does not. Somebody stood in a showroom, wanted a wide Italian gas range, and paid for it.
That changes the job in a way worth naming. These are kept, not replaced, so maintenance is worth doing properly rather than adequately. It also means the owner usually cares about how the front looks, which puts the fascia and the door glass higher up the priority list than they would be on a rental appliance where the cavity is all anyone inspects.
Our oven cleaning guide covers how a freestanding range differs from a built-in oven, including why cleaner must never be sprayed into the cavity on an appliance with a full-width control panel underneath it.
Width is the practical constraint
An Emilia at 900mm or 1000mm has a cavity considerably larger than a standard built-in, which means more surface, more cleaner and more dwell time. It also means a door heavy enough that removing it is a two-person job rather than an awkward one.
The width shows up in another way. A wide cavity is harder to keep in even contact with a cleaner, particularly on the roof, so laying a dampened cloth flat against the roof rather than wiping upward matters more here than on a 600mm oven where you can reach everything comfortably.
The cavity itself
Plain vitreous enamel on the great majority, with nothing to protect and nothing to ruin. Firm work with a non-scratch pad is fine, and repeat applications beat force on baked carbon.
The hob is part of it
Cast iron trivets and gas burner assemblies across the full width. See how to clean an Emilia cooktop, which on a freestanding model is the same appliance and the same afternoon.
What actually goes wrong
A wide cavity roof half done, because it is genuinely awkward to reach and wiping upward drains the cleaner off before it works.

Should you do it yourself?
Do it yourself for the cavity and the hob, treating them as one job.
Get someone in if the door needs to come off, or if the range is 1000mm or wider, where the scale stops being a Saturday morning.
