Cleaning the Inside of Cabinets: Division Method

To clean a cabinet from the inside, empty it completely and vacuum crumbs and dust, especially in the corners. Then wipe with a microfiber cloth slightly dampened with water and a neutral detergent, from top to bottom. Dry well and leave the doors open before putting things back. No disinfectants or harsh products are needed. What changes from cabinet to cabinet is the material, frequency, and what is stored inside: a cabinet with flour and rice is not treated the same as a wardrobe with wool coats. In this guide, we explain the method we use in the homes we clean in Lisbon, room by room, with the most common mistakes we see and the signs that it's worth handing the task over to professionals.

In summary

• Empty, vacuum, clean with little product, dry, and only then put things back. The order matters as much as the product.
• Just four products are enough for almost everything: dish detergent, a neutral multi-purpose cleaner, mild cleaning powder, and citric acid or vinegar, the latter only on surfaces that tolerate acid.
• The material dictates: microfiber on smooth and metal surfaces, soft cotton on wood and sensitive lacquers.
• Kitchen and pantry cabinets require a deep clean several times a year. Wardrobes and bathroom cabinets, at least at the change of season.
• If there is mold, persistent odor, or moths, cleaning is not enough: you need to find the cause, whether it's humidity, a leak, or contaminated food.

Why the inside of cabinets always gets left for later

Closed doors hide the problem. From the outside, the cabinet looks clean. Inside, it accumulates dust that enters every time the door is opened, crumbs from poorly sealed packages, oil and sauce drips on kitchen shelves, toothpaste and cream residues in the bathroom, sand and dirt in the shoe rack.

In the kitchen, this is more than an aesthetic issue. The ASAE recommends a hygiene plan that defines what is cleaned, how, when, and by whom, and that cleaning products are stored away from areas where food is handled. This plan was designed for establishments, but the logic applies to any home: a cabinet where food is stored is a contact surface with food and deserves routine, not a heroic effort once a year.

There is also the issue of humidity. In older homes, with cold walls or little ventilation, cabinets against exterior walls are the first to develop a musty smell. Regular cleaning allows you to catch an early dark spot at the bottom or a shelf that has started to swell.

What you need and what you can skip

The list is short. The German consumer protection association Verbraucherzentrale explains that four products are enough for cleaning the house and that disinfectants and harsh products are not necessary to keep a home clean and hygienic: dish detergent, a neutral multi-purpose cleaner, a mild cleaning powder (for example, based on calcium carbonate), and citric acid or vinegar on surfaces that are not sensitive to acids.

For the inside of cabinets, add:

• Vacuum cleaner with a narrow nozzle, for corners, drawer tracks, and holes in adjustable shelves.
• Microfiber cloths, for laminates, glass, stainless steel, and plastic.
• Soft cotton cloths, for solid wood, veneers, and delicate lacquers.
• A spray bottle, to apply the product to the cloth and not directly on the wood.
• An old toothbrush, for hinges, corners, and joints.
• Baking soda, to absorb odors in an open bowl after cleaning.

What you can skip: bleach inside wooden or kitchen cabinets, disinfectant wipes for everything, and scented sprays that only mask odors. Always store products in their original packaging, with the label visible. This is also the ASAE recommendation to avoid dangerous exchanges and have dosage instructions at hand.

The step-by-step method

This is the method we use, whether in a kitchen cabinet or a three-door wardrobe.

1. Empty everything. Don’t clean around the objects. Separate into three piles: keep, move to another room, throw away. In the kitchen, take the opportunity to check expiration dates.
2. Remove removable shelves and drawers. They clean better on the counter or in the bathtub, and this way you reach the back of the cabinet.
3. Vacuum from top to bottom. Crumbs and dry dust come out with the vacuum. If you wipe with a damp cloth right away, you turn them into paste.
4. Clean with little product. A few drops of neutral detergent in a bowl of warm water are enough. Austrian technicians from "die umweltberatung" warn that excess detergent leaves residues: more product does not clean better, and the sticky film that remains attracts dust faster.
5. Fold the cloth. Folded into four, a microfiber cloth gives you several clean sides. Keep turning it as it gets dirty and don’t spread dirt from one shelf to the next.
6. Treat difficult stains separately. Grease: dish detergent and warm cloth. Glass or limescale marks: diluted citric acid, only on surfaces that tolerate it. Dry residues: mild cleaning powder with light movements.
7. Clean inside doors, hinges, and handles. These are the most touched and forgotten parts.
8. Dry. Wipe everything with a dry cloth. Humidity trapped in a cabinet is the start of odors and mold.
9. Let it air out. Doors open for 15 to 30 minutes, or longer if the house is humid.
10. Organize thoughtfully. What you use most at eye level. In the kitchen, food in sealed jars. In the wardrobe, only clean and dry clothes.

Cabinet by cabinet: what changes

Kitchen and pantry cabinets

These are the ones that get the dirtiest and require the most care. Cabinets next to the stove and extractor fan develop a fine layer of grease, even inside, because steam enters through the cracks of the doors. Start with these, using warm water and dish detergent, and dry immediately.

In the pantry, the enemy is crumbs and open packages. Flour, rice, pasta, and nuts stored in poorly sealed paper or plastic packaging attract food moths and other insects. If you find fine webs, larvae, or small butterflies, throw away the affected food, vacuum all the cracks and holes in the shelves, clean and dry well before putting things back, now in airtight jars. If the problem returns, call a pest control company: there are cases where the source is outside the cabinet.

!

Do not store detergents in the same cabinet as food. Under the sink, use a tray or waterproof base. If a new water stain appears, check the siphon before cleaning, as a small leak can damage the baseboard in a few weeks.

The same logic of clean shelves and organization by zones applies to the refrigerator, which the ASAE recommends keeping at a temperature of 3 to 4 °C.

Wardrobes and dressers

In the wardrobe, the dirt is mainly dust and lint from the clothes themselves. Vacuum the floor of the wardrobe and the tracks of the sliding doors well, where lint accumulates and makes the doors stick. Clean the shelves with a cloth only dampened and dry.

The biggest concern here is humidity. Never store still damp clothes from the machine or drying rack, and leave a small gap between the wardrobe and the wall, if the furniture allows. If you notice a musty smell, empty it, wash the affected clothes, clean the inside, dry very well, and leave the wardrobe open for a whole day. A bowl of baking soda helps absorb the lingering smell, but does not solve the cause. If the wall behind is cold and stained, the problem is humidity or condensation in the house, not the furniture.

Some wardrobes and wall niches are lined with wallpaper. If this is the case, check the care for washable wallpaper maintenance before applying water, as not all wallpapers can withstand the same treatment.

Bathroom cabinets

Here, limescale, residues from hygiene products, and constant humidity come together. Remove everything, throw away expired cosmetics and medications (medications should be returned to the pharmacy, not thrown in the regular trash), and clean the shelves with a neutral multi-purpose cleaner. For white limescale marks on glass or plastic, use diluted citric acid and rinse with a damp cloth.

If the cabinet is made of particle board with melamine coating, be careful with the edges: water that enters through a lifted edge causes the board to swell. Always dry the corners well.

Shoe racks and entry cabinets

Vacuum first, as dirt and sand can scratch the shelves if dragged with a cloth. Then clean with a damp cloth and dry. Let shoes air out before storing them, and if there is an odor, a bowl of baking soda at the bottom helps.

Material care

The material of the cabinet dictates the cloth and the product. "die umweltberatung" recommends microfiber for smooth surfaces and cotton for sensitive ones, to avoid wearing down the finish. Always do a test in a discreet corner when you are unsure what you have at home.

Material	Cloth	Product	Avoid
Laminate and melamine	Damp microfiber	Neutral multi-purpose or diluted dish detergent	Soaking edges and corners
Solid or veneered wood	Soft cotton, well wrung	Water with a drop of neutral detergent	Vinegar, abrasive powder, excess water
Lacquered	Cotton or very soft microfiber	Warm water and neutral detergent	Sponges with green side, alcohol
Glass	Microfiber	Water or very diluted citric acid	Cloth with grease residues
Stainless steel and metal	Microfiber	Diluted dish detergent; dry in the direction of the finish	Steel wool, bleach
Plastic and acrylic	Microfiber	Neutral multi-purpose	Abrasive products
Natural stone (marble, limestone) on shelves	Microfiber	Neutral detergent	Vinegar and citric acid

A trick from professionals: use different colored cloths for each area of the house. The guide from "die umweltberatung" for cleaning teams proposes a color code for cloths to avoid carrying dirt from one room to another. At home, just a pair of colors is enough: one for the kitchen and another for everything else.

How often to clean each cabinet

There is no one-size-fits-all rule. It depends on usage, how many people live in the house, and what each cabinet stores. This is the frequency we recommend to the families we work with:

Cabinet	Quick clean	Deep clean
Kitchen, next to the stove	Monthly (daily use shelves)	Every three months
Pantry	Whenever crumbs fall or spills occur	Every three months and before restocking
Under the sink	Monthly (check for leaks)	Twice a year
Wardrobes	At the change of seasonal clothes	Twice a year
Bathroom	Monthly	Twice a year
Shoe rack and entry	Biweekly in winter	Twice a year

If you want to fit this into a plan for the whole house, our house cleaning calendar shows the frequency of each task, and the guide to cleaning by division combines what to do in each space.

The most common mistakes we see

• Wiping without emptying. Dirt stays under jars and the bottom is never cleaned.
• Soaked cloth. On wood and particle board, excess water causes edges to lift and boards to swell. The cloth should be damp, never dripping.
• Too much product. Leaves a film, attracts dust, and wastes money.
• Vinegar on everything. Works on glass and some plastics, but stains natural stone and can dull certain finishes.
• Putting things back right away. A still damp closed cabinet develops odors in a few days.
• One cloth for the whole house. The cloth that cleaned the bathroom should not go into the food cabinet.
• Masking the smell instead of solving it. An air freshener in a moldy wardrobe only hides a humidity problem that will continue to grow.

When it pays to call professionals

Cleaning the inside and outside of a complete kitchen's cabinets easily takes a morning. Adding wardrobes, bathrooms, and pantry, it’s a weekend. There are times when it makes sense to hand over the task:

• Before moving in or after moving out of a rental property. Cabinets are the first place a landlord or new tenant opens. See how our move-in and move-out cleaning works and the real case of a T2 in Campo Grande that hadn’t had professional cleaning in a year.
• After renovations. The fine dust from the renovation gets into all drawers and shelves, even with doors closed. Our post-renovation cleaning takes care of it before putting things back.
• In a holiday home or second residence. Cabinets closed for months develop odors and humidity. The Residence Care service exists to keep these homes ready to use.
• When there simply isn’t time. The demand for cleaning services in Portugal grew by 27% at the beginning of 2026 compared to the same period the previous year, and many of those families are exactly in this situation.

Whatever company you choose, ask for a written quote detailing what is included and do not accept pressure to decide on the spot. The Austrian Chamber of Labor, the Arbeiterkammer, recommends being wary of "special cleaning" offers with discounts that only last a few days and never signing anything under pressure. Prefer established companies with their own team and a clear checklist.

Cabinets inside, with the Cleaning Point standard

At Cleaning Point, we work in Lisbon with fixed teams whenever possible, professionals selected and trained by us, and detailed checklists that show you what has been done. If you want the cabinets treated from the inside, our Deep Cleaning Signature is the starting point, and the oven, appliances, or balcony can be added as extras. Let us know when booking which cabinets to empty and if you prefer to be present when we open wardrobes and drawers. You can book a cleaning online, with support in several languages.

What we learned from opening cabinets in Lisbon

In our experience, the inside of a cabinet says more about the state of a house than any visible surface. It’s where the first moisture stain appears, the first moth in the pantry, the first lifted edge under the sink. That’s why we treat cabinets as an inspection, not just a cleaning: when we see something that isn’t right, we tell the client, instead of cleaning and closing the door.

!

There is also a privacy issue. Cabinets hold clothes, documents, medications, personal items. It’s one of the reasons we don’t work with random third parties and prefer to keep the same team in the same house: whoever opens your wardrobes should be someone you already know and who follows the same rules each time. We put everything back as it was, unless requested otherwise, and we don’t throw anything away without permission, not even an expired package of flour.

Finally, the standard. A cabinet well cleaned by one person and poorly cleaned by another serves no one. The checklist exists to ensure that the result is the same, regardless of which professional comes to your home.

Frequently asked questions

Can I use vinegar to clean the inside of cabinets?

On glass, plastic, and some laminates, yes, always diluted. On solid wood, lacquered surfaces, and natural stone shelves, like marble, avoid: the acid can dull and stain. When in doubt, use warm water with a drop of neutral detergent and test first in a hidden corner.

How to remove the musty smell from a wardrobe?

Empty the wardrobe, wash the smelly clothes, clean the inside with a cloth only dampened, and dry very well. Leave the doors open for a day and place a bowl of baking soda inside. If the smell returns, check the wall behind the furniture: the problem is usually humidity in the house.

Do I need to disinfect kitchen cabinets?

In a home, usually not. Neutral detergent, water, and good drying are enough to keep cabinets clean and hygienic. The exception is a spill of raw meat or spoiled food: clean immediately with detergent and hot water and dry well.

How long does it take to clean all the cabinets in a kitchen?

It depends on the size and how much is stored, but in a typical kitchen, expect two to four hours, including emptying, cleaning, drying, and organizing. Those who do a quick monthly clean significantly reduce this time for deep cleaning. In a professional cleaning, the duration depends on what you request and the state of the house.

Is cleaning the inside of cabinets part of regular cleaning?

In a weekly or biweekly maintenance, the usual practice is to clean the cabinets from the outside and the visible surfaces. The inside, which requires emptying everything, is usually left for a deep clean or a move. When booking, always tell us which cabinets you want cleaned inside, so we can plan the right amount of time.
