Cleaning the Extractor Hood and Grease Filter Before Handover

If you are preparing for a Swiss apartment handover, the extractor hood above your stove deserves more attention than it usually gets. Extractor hood grease filter cleaning is one of the most commonly failed items during a move-out inspection, because grease builds up slowly and is easy to underestimate until the light hits it at the wrong angle.

Why the Extractor Hood Is a Handover Danger Zone

Grease from cooking rises with steam and settles on the nearest cool surface, which is almost always the underside and housing of the cooker hood. Over months of regular cooking, this builds into a sticky film that ordinary wiping cannot shift.

Inspectors trained on HEV-style handover checklists look at three things on the extractor hood:

•         The outer housing and control panel, checked for grease film and fingerprints

•         The grease filter mat, checked for saturation and discolouration

•         The ceiling and light fitting directly above the hob, often overlooked by tenants

Because grease is invisible under normal kitchen lighting but obvious under an inspector's torch, this is one of the highest-risk items on a kitchen handover checklist.

Grease Filter Mats: Clean or Replace? What the Checklist Says

This is the detail most cleaning guides get wrong. Metal grease filter mats can usually be cleaned successfully. However, most Swiss handover checklists, including the standard used by the HEV, treat the grease filter mat as a normal wear item that is typically replaced at handover, not simply cleaned.

In practice, this means:

•         If your filter mat cleans up completely and looks like new, cleaning may be accepted.

•         If it still shows discolouration, warping, or a residual smell after a proper soak, replacement is the safer and often expected route.

•         Carbon or activated-charcoal filters cannot be cleaned at all. These are consumable and must always be replaced, never washed.

Knowing which type you have before you start saves time. Metal mesh filters are dishwasher-safe. Carbon cartridges are not, and washing one will only ruin it faster.

Step-by-Step: Cleaning the Extractor Hood Housing

1. Switch off the appliance at the wall and let the surface cool completely.
2. Remove the filter mat first (usually a simple push-and-slide or clip release; check your model's manual).
3. Wipe the housing, control panel, and underside with warm water and a degreasing kitchen spray, working in small sections.
4. For stubborn baked-on grease, apply the degreaser, leave it for 5 to 10 minutes, then wipe with a microfibre cloth.
5. Dry the housing fully before switching the appliance back on.
6. Clean the ceiling area directly above the hood and any nearby light fittings, since grease travels further than most people expect.

Key takeaway: always clean the housing before the filter goes back in. Reinstalling a filter into a still-greasy housing undoes half the work.

The Dishwasher Soak Method for Grease Filters

This is the most effective non-chemical method for metal mesh filters, and it is genuinely hand-over-grade when done properly.

7. Confirm your filter is metal, not carbon (check the manual, or hold it to light: metal filters are mesh or perforated aluminium).
8. Place the filter flat or upright in the dishwasher, ideally on its own or with minimal other items.
9. Run a hot cycle (60°C or higher) without detergent tablets if the mesh is delicate, or with a standard tablet for heavily soiled filters.
10. For extremely greasy filters, pre-soak in a bucket of hot water with dish soap and a splash of white vinegar for 30 minutes before running the dishwasher cycle.
11. Let the filter air dry completely before reinstalling. A damp filter trapped inside a warm hood housing can develop odour.

If, after this cycle, the mesh is still yellowed, warped, or holding a stale smell, that filter has reached the end of its useful life and should be replaced rather than run through a second cycle.

Common Mistakes That Fail the Handover Inspection

•         Cleaning the housing but skipping the filter. Inspectors check both.

•         Using abrasive scourers on brushed steel, which leaves visible scratch marks that count against you.

•         Reinstalling a wet filter, which traps moisture and creates odour by the inspection date.

•         Forgetting the ceiling above the hob, a spot that grease reaches long before it reaches eye level.

•         Assuming a “clean-looking” filter passes, when the checklist calls for replacement regardless of appearance.

Replacement Filter Mats: Where to Buy and What They Cost

If your filter needs replacing, universal metal mesh filters and brand-specific carbon cartridges are both readily available in Switzerland from major electronics and appliance retailers, as well as directly from your hood manufacturer's parts service using the model number printed inside the housing or on the original filter.

Replacement is usually a low-cost, quick swap and is by far the cheapest way to guarantee a pass on this specific checklist item compared with the cost of a failed inspection and re-clean. Keep the receipt for the new filter; some Verwaltungen accept proof of replacement as evidence the item has been addressed correctly.

DIY vs Professional Deep Cleaning: When to Call for Help

If you are already running low on time before your move-out date, this is exactly what a professional deep cleaning visit is built to cover, kitchen appliances included.

Deep Cleaning Prices by Apartment Size (Zurich)

If DIY cleaning is not enough or your inspection date is close, here is what a professional deep cleaning currently starts from, by room size:

Prices are starting prices in CHF and cover a full deep clean, with the extractor hood, filter, hob and oven included as part of the kitchen scope.

Extractor Hood Maintenance Schedule for Rented Flats

Keeping to this schedule during your tenancy means the handover clean is a quick top-up, not a full grease-removal project.

Why Zurich Tenants Bring in a Professional Team for Handover Cleaning

Grease that has been left for a year or more often needs stronger degreasing agents and equipment than a household kitchen cupboard holds. A professional end of tenancy cleaning covers the extractor hood as part of a full kitchen scope, alongside the hob, oven, and cupboards, all mapped against the same checklist your Verwaltung will use.

If you replace filter mats yourself, old cartridges and mats can go through your building's usual electronic or general waste stream; for larger clearance jobs during a move, Züriclean's disposal service can take care of it in the same visit.

Conclusion

A greasy extractor hood is a small detail with an outsized effect on a Swiss handover inspection. Cleaning the housing properly, running metal filters through a proper dishwasher soak, and replacing worn filter mats rather than hoping they pass will put this item solidly on the “checked” side of your list.

Frequently Asked Questions

Can I clean the grease filter myself before handover, or does it have to be replaced?

Metal mesh filters can be cleaned in most cases. However, Swiss handover checklists typically classify the filter mat as a wear item that is normally replaced. If yours is discoloured or still smells after cleaning, replacement is the safer choice.

Can I put my extractor hood filter in the dishwasher?

Yes, if it is a metal mesh filter. Run it on a hot cycle, ideally after a warm-water pre-soak for heavy grease. Carbon or charcoal filters must never go in the dishwasher and cannot be cleaned at all.

How often should I clean my cooker hood filter while renting?

A monthly rinse and a full dishwasher soak every two to three months keeps grease from building up. This makes the final handover clean much faster and avoids a last-minute replacement.

What happens if the inspector finds a greasy extractor hood at handover?

It is usually logged as a defect requiring a re-clean, which can delay deposit release and, in some cases, be charged to the tenant. A quick clean or filter swap beforehand avoids this entirely.

Should I hire a professional cleaner for the extractor hood specifically?

For light grease, DIY cleaning is usually enough. For heavy, long-term buildup or tight timelines, a professional deep cleaning visit covers the hood alongside the rest of the kitchen, with a guarantee against a failed inspection.
