Deep Cleaning in Singapore: A Room-by-Room Guide for HDB, Condo and Landed

Deep cleaning in Singapore means cleaning the parts of a home that a weekly wipe-down never reaches: the grease film on top of the cooker hood, the dust caked on ceiling fan blades, the black spots in the grout, the tracks of every sliding window, and the dirt behind and under furniture. Most households need one two to four times a year, plus a one-off reset after moving, renovating or a long stretch without help.

This guide explains what separates a deep clean from routine cleaning, works through the home room by room, and gives realistic hour estimates so you can plan a budget. Each section links to a more detailed guide if you want to tackle that job yourself.

Deep cleaning vs regular cleaning

A regular clean maintains. A deep clean restores. The difference is less about effort and more about which surfaces get touched.

If your home is cleaned weekly or fortnightly, a deep clean is mostly about the high, low and hidden places. If it hasn't been cleaned properly for months, expect everything in the right-hand column and more time on each item.

Why Singapore homes need deep cleaning more often

Three local conditions speed up build-up:

• Humidity. Relative humidity here sits high all year, so moisture lingers in bathrooms, wardrobes and behind furniture. That is where mould starts.
• Wok cooking. High-heat stir-frying throws fine oil droplets into the air. They settle on the hood, the wall tiles, the top of the fridge and even the ceiling near an open kitchen, then trap dust.
• Dust from outside. Construction in new estates, traffic on main roads, and haze in some years all bring fine dust through open windows and grilles. Many HDB flats keep windows open for ventilation, so dust settles quickly on fans, ledges and blinds.

The monsoon seasons add to this. The Northeast Monsoon, roughly December to early March, brings long wet spells, and damp weeks are when wardrobes and walls start to smell musty.

How often should you deep clean?

A practical schedule for most households:

• Every 3 to 4 months: a partial deep clean of the kitchen and bathrooms, the two rooms that degrade fastest.
• Twice a year: a whole-home deep clean, often timed before Chinese New Year and mid-year.
• One-off: when moving in or out, after renovation, after illness in the household, or when taking over a rental.

Homes with young children, pets, allergy sufferers or heavy daily cooking benefit from the shorter end of each range. Our Chinese New Year cleaning checklist is a good template for the big annual session.

Room-by-room deep cleaning guide

Work top to bottom and dry to wet: dust high surfaces first, then wipe, then do floors last so falling dirt is picked up once.

Kitchen

The kitchen takes the most time in almost every Singapore home. Start with the cooker hood, because degreasing it drips onto everything below. Then the hob, backsplash tiles, cabinet fronts and tops, the fridge, and finally the floor, which in a kitchen with heavy cooking often has a sticky film that needs a degreasing mop solution.

Service yard and laundry area

HDB service yards and condo utility areas collect lint, damp and clutter. Clean the floor trap, the laundry rack, and the washing machine drum, seal and detergent drawer, which are classic sources of a sour smell. See service yard and laundry area cleaning and washing machine cleaning.

Bathrooms

Deep cleaning a bathroom means descaling shower glass and taps, scrubbing grout and silicone, clearing hair from drains, and cleaning the exhaust fan cover so the room can dry out properly. Our guide to the toilet and bathroom spots people miss lists the hidden areas one by one.

Living room

Dust the ceiling fan and light fittings first, then aircon covers, shelves, the TV console and skirting. Vacuum the sofa including under the cushions. Pull lighter furniture away from the wall to get the dust line behind it.

• Curtain and blind cleaning

Bedrooms

Mattresses, wardrobes and window dressings are the deep-clean items here. Vacuum the mattress and flip or rotate it, wipe wardrobe interiors and check corners for mould, and clean the window tracks and grilles.

• Window grille and track cleaning in HDB flats

Walls, ceilings and damp corners

Look for grey or black spotting on ceilings above showers, behind wardrobes on external walls, and in corners that get little air. Surface mould can be cleaned; recurring patches usually point to a ventilation or leak problem. Our guide to mould on walls and ceilings explains how to tell the difference.

Floors

Floors are done last. Different materials need different treatment: marble is etched by acidic cleaners, vinyl and SPC can lift if flooded, and grout on ceramic tiles needs a brush rather than a mop.

• Marble floor cleaning
• Vinyl flooring cleaning

Balcony, entrance and storage

Balconies gather grit, bird droppings and stagnant water in plant saucers. The shoe cabinet by the door is often the source of an unexplained smell in the living room. And in family homes, the toy shelf deserves its own session.

How long a deep clean takes, and what it costs

Time depends on size, how long since the last thorough clean, and how much cooking and clutter is involved. The figures below are rough estimates of total cleaner-hours for a home in average condition. A heavily neglected home, or one straight after renovation, can take noticeably longer.

These are estimates, not quotes. Two cleaners working together halve the clock time, but the cleaner-hours stay about the same. If you set up a recurring plan afterwards at $23/hr, the regular sessions stay shorter because the deep build-up is already gone.

What you need to prepare

At Cleaning Assistant, customers provide the cleaning supplies and equipment. That keeps costs down because nothing is marked up, and it means you choose exactly what is used around children, pets and delicate surfaces. For a deep clean, have these ready:

• A degreaser for the kitchen and a bathroom cleaner suited to your tiles
• A descaler for glass and taps, and a mild neutral cleaner for marble or timber if you have them
• Microfibre cloths (plenty), a scrubbing brush, an old toothbrush for tracks and grout
• A vacuum with a crevice tool and upholstery brush, a mop and two buckets
• A stable step ladder for fans, cabinet tops and light fittings

Our home cleaning supplies shopping list covers this in more detail, and please never mix bleach with acids or ammonia; see dangerous cleaning product combinations.

What deep cleaning does not include

A household deep clean covers what can be reached and cleaned safely with household products. It does not include internal aircon servicing or chemical washes, which need a licensed aircon technician; pest control; or exterior window work on high floors that cannot be reached safely from inside. Mould caused by a leak also needs the leak fixed first. For empty homes, our move-out cleaning guide covers the handover-specific extras, and post-renovation dust is a different job again, explained in the ultimate guide to post-renovation cleaning.

Frequently asked questions

How is a deep clean different from spring cleaning?

They overlap a lot. Spring cleaning usually includes decluttering and reorganising, while a deep clean focuses on removing built-up grime from surfaces, fittings and soft furnishings. Our post on spring cleaning in Singapore covers the decluttering side.

Should I deep clean before or after Chinese New Year preparations?

Do the deep clean first, ideally a week or two before the festive period, then a lighter tidy-up just before visitors arrive. Booking early also helps because demand rises in the weeks before the holiday.

Can a part-time cleaner do a deep clean, or do I need a specialist?

A trained part-time cleaner can handle household deep cleaning: kitchens, bathrooms, fans, tracks, grilles and soft furnishing vacuuming. Specialists are needed for internal aircon servicing, pest control, and steam extraction of heavily soiled upholstery.

How many hours should I book for a first deep clean?

Use the table above as a starting point and lean towards the upper estimate if the home has not been cleaned thoroughly in six months or more. It is easier to finish early than to leave rooms half done.
