Most people lose a deep clean to the order they do it in rather than to the products they use. This is the sequence a professional team works in, the spots that get skipped in almost every house, and the handful of things that will damage a home if you get them wrong.
How do you deep clean a house?
Deep clean a house top to bottom and dry before wet, one level at a time. Cobwebs and dust come down first, then fixtures and hard surfaces get washed, then floors last. Working in that order means nothing you knock loose lands on something you have already finished.
The order matters far more than the cleaner in the bottle. Most people lose an afternoon by mopping a floor and then dusting the ceiling fan above it, or by taking one room to a high standard while the next four stay untouched and the dust migrates back.
There is one refinement worth knowing, and it is the single most useful thing on this page. Dust an entire level first — cobwebs, fans, light fixtures, door trim, doors, window sills, window trim and baseboards — before you touch any furniture or objects. Anything stirred up then has time to settle while you work, so you collect it on the way through instead of finding it tomorrow.
Where should you start deep cleaning?
Start at the top of the house and the top of each room, and take the rooms that take longest — kitchen and bathrooms — while you still have energy. Do floors across the whole house in one pass at the end rather than room by room.
A working sequence for a whole house looks like this:
- Clear the surfaces first. Anything that has to be picked up and set down again doubles the time. Twenty minutes clearing counters saves an hour later.
- Dry dust the whole level. Ceiling corners, fan blades, light fixtures, vents, the tops of door frames, blinds, sills, then baseboards. A vacuum brush attachment beats a cloth for the first pass.
- Wash the hard surfaces. Cabinet fronts, doors, frames, trim, baseboards, switch plates, handles and handrails.
- Kitchen and bathrooms in detail. These two rooms are where the day actually goes.
- Glass and mirrors.
- Floors last. Vacuum everything, then mop, working backward toward a door.
If you want the room-by-room task list rather than the sequence, our house cleaner checklist writes out every task in every room, with a maintenance visit and a deep clean set side by side.
How do you deep clean baseboards?
Vacuum the dust off first with a brush attachment, then wash with warm water and a drop of dish soap on a damp cloth, and dry as you go. The full answer is in our guide to how to clean baseboards, and what to clean them with.
What are the places people forget to clean?
The forgotten places are the ones nobody looks at directly: the bottom edge of the dishwasher door, window and door tracks, the tops of door frames, the range hood filter, the gaps beside the appliances, and the strip of floor just inside the front door.
The kitchen ones
- The bottom edge and metal lip of the dishwasher door. Open the door fully and look at the underside of the lip. That ledge collects food residue and is a common source of a dishwasher smell people blame on the drain. Spray a degreaser, let it sit, scrub, and repeat if needed.
- The range hood filter. The mesh loads with grease until it stops pulling air properly. Soak it in hot water with dish soap.
- The cabinet doors above the range. Grease travels much farther than people expect and lands as a film you cannot see. A cloth coming away brown is the test.
- The gaps beside and behind the range and refrigerator, plus the top of the refrigerator.
- The trash can itself, not just the bag in it.
The laundry ones
The dryer is the one worth taking seriously, because it is a fire risk rather than only a dirt problem. The US Fire Administration reports that failure to clean was the leading factor contributing to home clothes dryer fires from 2018 to 2020, at 31 percent.
- Clean the lint filter before every load, and pull the lint out of the housing the filter sits in a few times a year.
- Check the vent duct behind the dryer and the exterior vent flap.
- On a front-load washer, wipe the door gasket and check the drain filter. That fold holds water and is the usual source of the smell.
Worth saying plainly: Happy Maids does not do laundry or laundry folding, and does not clean inside the dishwasher, washing machine or dryer. Both are published exclusions, listed on our policies page rather than left as judgment calls on the day. A dryer vent in particular belongs to an appliance technician.
The ones in every room
- Window and door tracks. Sprinkle baking soda in the track, spray with white vinegar, let it foam, then wipe out with a cloth wrapped around a butter knife. Fine on aluminum and vinyl tracks, but keep vinegar off marble, travertine, limestone and unsealed grout, which acid etches.
- The tops of door frames and the top edge of the doors themselves. Nobody sees them and everybody's are gray.
- Supply and return vents. Vacuum the grille with a brush attachment. A hallway return loads up faster than anything else in the house.
- Light switch plates, door handles, door frames and handrails. These are the surfaces hands actually touch, and they are the first thing a guest registers without knowing why.
- The shower door track, and the hinges and underside of the toilet seat.
- The strip of floor inside the front door, which is the highest-value square foot in an Illinois house between November and March.
How do you clean ceiling fan blades and vents safely?
Slide an old pillowcase over each fan blade, close it around the blade and pull it back toward you. The dust ends up inside the case instead of on the bed below. Do it from a step stool you are steady on, never from a chair and never above the second step of a ladder.
Fan blades are the surface people misjudge most. The top of a blade is a horizontal shelf at head height, it holds more dust than any other single surface in a bedroom, and the fan throws all of it into the room every time it runs.
Height is also where a home cleaning project turns into an emergency room visit. Happy Maids works to a published limit of the second step of a step ladder and uses extension poles where they reach; a fixture hanging in a two-story foyer gets referred to a specialist rather than attempted. That is a good rule for a homeowner as well as for a crew.
What is the dark line along the carpet at the baseboards?
That is filtration soiling, and it is not ordinary dirt. Air moving between rooms and floors passes through the edge of the carpet, and the carpet acts as a filter, so fine airborne soil collects in a dark line along the baseboard and under doors. Vacuuming will not lift it.
What helps at home is a white cotton cloth run back and forth along the base of the trim, which balls the lint and loose dust so it can be vacuumed up. Use white, because a dyed cloth can transfer color into damp carpet. Watch for protruding trim nails and carpet staples along that edge.
The rest of it is a carpet cleaner's job. Happy Maids does not shampoo, steam clean or extract carpet; we vacuum with sealed-HEPA machines and say so up front rather than on the day. If something needs to come out of the fibers, book a carpet cleaner separately and have that done last, after everything else.
What should you never do when deep cleaning?
Never mix bleach with ammonia, or bleach with any acid including vinegar. The combination produces chloramine or chlorine gas in an enclosed bathroom within seconds. Everything else below is about damage that does not come back off, which deserves more caution than cleaning advice usually gives it.
- No acid on natural stone. Vinegar, lemon juice and acidic bathroom cleaners etch marble, travertine, limestone and honed stone on contact. Etching is physical damage rather than a stain, so it does not clean off. Use a pH-neutral stone cleaner.
- No abrasive pads on shower glass or glazed tile. They scratch glass and dull glaze permanently. Mineral film comes off a layer at a time with standard supplies and repetition, which is the slower trade and the right one.
- No wet mopping on unsealed or unfinished wood, and none at all on a floor that has been sanded but not yet finished. Water raises the grain and it does not go back down.
- No melamine sponge on gloss, semi-gloss or aged paint, or on a glossy appliance finish.
- No damp-wiping paint that has not cured. Latex needs two to four weeks.
- Check the manual before running vinegar through a dishwasher or soaking a fixture in it. Manufacturers differ, and some seals and coated finishes are explicitly not rated for it.
Ventilate while you work. The EPA's guidance on improving indoor air quality is that source control is usually the most effective step, with increasing outdoor air the next one, so open a window and run the exhaust fan while cleaning rather than afterward.
How long does it take to deep clean a house by yourself?
A first deep clean typically runs several hours with a team of two or three, and the condition of the house matters more than its square footage. The full answer is in our guide to how long it takes to deep clean a house.
When is it worth hiring someone instead?
Hire it out when the house is far enough behind that the first pass is a recovery job rather than a cleaning. That first visit is the hard one and the one people abandon halfway through. After it is done, a maintenance rhythm holds the house there without another long weekend.
Happy Maids has been doing this in the Barrington area since 1985. Deep cleans are priced by the time the home actually takes, charged hourly and pro-rated every ten minutes, while recurring house cleaning is a flat, predictable rate. Call or text 847-382-0082 and a person in our Lake Barrington office will pick up; the estimate is free and there is no contract.
If you want the detail first, our post on what a deep clean includes covers what changes between a maintenance visit and a deep clean, and how often to deep clean your house covers the interval room by room. The deep cleaning service page explains what we do on that first visit, and our policies page publishes the whole exclusion list rather than discovering it with you on the day.
Frequently asked questions
How do you start deep cleaning a house?
Clear the surfaces, then dust an entire level top to bottom before touching furniture or objects: cobwebs, fans, fixtures, door trim, doors, sills, window trim, then baseboards. Anything stirred up settles while you keep working, so you collect it on the way through. Wash hard surfaces next, and do floors last across the whole house in one pass.
How do you deep clean baseboards without damaging the paint?
Vacuum the top edge with a brush attachment first, then wipe with a microfiber cloth wrung out in warm water with a drop of dish soap. Never use a melamine foam eraser on gloss, semi-gloss or older paint, because it is a fine abrasive and it burnishes the finish. Never damp-wipe trim painted in the last two to four weeks, as latex has not cured.
What is the correct order to deep clean a room?
Top to bottom and dry before wet. Ceiling corners and fixtures, then fan blades, vents, the top of door frames, blinds and sills, then baseboards, then the washing of cabinet fronts, doors, trim, switch plates and handles, then glass and mirrors, and floors at the very end.
How often should baseboards be washed?
Twice a year in most homes, and more often in a kitchen or an entryway. In an Illinois home, one of those should fall right after the road salt stops, because grit tracked in from November through March settles along the base of the trim and grinds into the floor edge.
Can you use vinegar to clean everything?
No. Vinegar is an acid, so it etches marble, travertine, limestone and honed stone on contact, and etching is physical damage rather than a stain. It also attacks unsealed grout. Never combine it with bleach, which releases chlorine gas. It works well on aluminum and vinyl window tracks and on glass.
Do professional house cleaners clean ceiling fans and air vents?
Yes, within reach. On a Happy Maids visit fan blades, vents, light fixtures and cobwebs in ceiling corners are done in every room, dusted on a maintenance clean and hand-washed on a deep clean. Nothing is cleaned above the second step of a step ladder, so a fixture in a two-story foyer needs a specialist with the right equipment.
How much should you tip house cleaners for a deep clean?
Tipping is never required. If you would like to, Happy Maids suggests an amount equivalent to 10 to 20 percent of the cleaning cost. There are three ways: the Add a Tip form on your card, once or recurring; the post-clean survey; or cash in an envelope marked for the cleaners. Our cleaners are W-2 employees, so no one's wage depends on it.
Does a professional deep clean include the inside of the oven and refrigerator?
No, both are add-ons on every service, including a move-out. So are inside emptied cabinets, interior windows within step-ladder reach, vacuuming inside the sofa, a linen change, and a finished basement. Ask for any of them at least one business day ahead so the time is built into the visit rather than squeezed into it.
