Plain vitreous enamel with no self-clean, so a non-caustic cleaner with a genuine thirty minute dwell and a second application handles it. If you are cleaning the oven, the matched rangehood is almost certainly the reason you are doing it this often.
Venini is a house brand sold by The Good Guys, supplied as a kitchen package rather than as individually chosen appliances.
The oven is the symptom, not the cause
Most people arrive at this page because the Venini oven has started smoking or smelling, and the oven is genuinely what needs cleaning. It is rarely what caused the problem.
In a package kitchen the three appliances went in together and have done identical work, but they receive wildly different attention. The oven gets cleaned because it forces the issue. The cooktop gets wiped because it is visible. The rangehood gets nothing, because it never fails outright.
A hood that has stopped extracting properly returns cooking grease to the room, where it settles on the cooktop and on the front and interior of the oven. So the appliance nobody maintains is quietly determining how often the appliance everybody maintains needs doing.
If your Venini oven seems to need cleaning more often than it should, that is the thing worth checking. See how to clean a Venini rangehood and how to clean a Venini cooktop.
Nothing to protect, which makes it straightforward
Venini cavities are plain vitreous enamel. No catalytic liner, no non-stick treatment, no self-clean cycle on the overwhelming majority.
That means there is nothing you can accidentally destroy and no shortcut either. A non-caustic cleaner, roof first, a genuine thirty minute dwell, firm work with a non-scratch pad, and repeat rather than escalate. Our oven cleaning guide covers it.
Finding a part
Venini is a Good Guys house brand, so a door seal or a shelf set comes through the retailer rather than a manufacturer network, and the model number from the rating plate is what they will ask for. Photograph it before you start.
Where the smoke is actually coming from
When a Venini oven smokes, people reasonably assume the cavity. It is frequently the grill element or the area immediately around it instead.
The grill sits at the top of the cavity, so anything that has spattered upward over the years is directly on and around it, and unlike the cavity walls it reaches red heat rather than a few hundred degrees. Deposits that sit quietly through a roast will smoke instantly under a grill.
The practical consequence is that an oven can smoke on the grill setting while behaving perfectly on bake, and cleaning the walls and floor thoroughly will not change that. Clean the roof around the element carefully with a cloth rather than a spray, keep liquid off the element itself, and let it dry completely before use.
If it still smokes on grill after a genuine clean, the element may have deposits baked onto the element itself, which is a different job and not one to attack with a pad.
What actually goes wrong
One application and a conclusion, on a cavity that needed three.
Escalating to abrasives, which dulls the enamel and makes every future clean harder.
A parts search aimed at a manufacturer rather than at the retailer.
A matched hood never opened.
Should you do it yourself?
Do it yourself. There is nothing here to ruin and dwell time does the work.
Get someone in if it has years of hard carbon, or at end of lease where a standard rather than a best effort is required.
