# The 7-step cleaning process: order of work, dwell times and the three types of cleaning

> The 7 step cleaning process comes from hospital environmental services: pull waste, high dust, damp wipe, stock supplies, clean the bathroom, damp mop, inspect. It works in homes and offices because it fixes the order of work so nothing is missed and dust never falls on a wet floor. The three types of cleaning inside it are cleaning (removing soil), sanitizing (lowering germs to a safe level) and disinfecting (killing them), and each product needs its label contact time.

## Key takeaways

- UNC Hospitals’ routine 7-step method: 1 pull waste and linen, 2 high dust, 3 damp wipe, 4 stock supplies, 5 clean bathroom, 6 damp mop floors, 7 inspect work.
- Cleaning removes germs and dirt with detergent and water; disinfecting kills germs with chemicals; sanitizing lowers germs to a safe level by either method (Tennessee DOE, MedlinePlus).
- Clean before you disinfect: dirt stops the chemical working, and a disinfectant does not necessarily clean a dirty surface.
- Contact time is on the label: EPA says the surface should stay visibly wet for the whole time, which spray-and-wipe never achieves.
- Order of work: top to bottom, dry before wet, clean to dirty, back of the room to the door.
- Never mix bleach with ammonia, acids or other cleaners: Washington’s health department warns that bleach and ammonia release toxic chloramine gases, and bleach and acids release chlorine gas.

## What is the 7-step cleaning process?

The 7-step cleaning process is a fixed order of tasks for cleaning a room, written for hospital environmental services and now used far beyond hospitals: pull waste and linen, high dust, damp wipe, stock supplies, clean the bathroom, damp mop the floor, inspect. The point is not the number seven. It is that every room is done the same way, by every cleaner, in an order that keeps dust off clean surfaces and feet off wet floors.

The clearest published version is the one UNC Hospitals’ environmental services department attaches to its policy as [“The 7-Step Cleaning Method”](https://spice.unc.edu/wp-content/uploads/2024/06/ES-Att-2-The-7-Step-Cleaning-Method-.pdf). It lists three variants side by side:

| Step | Routine (occupied room) | Discharge (room turnover) | Policing (quick pass) |
| --- | --- | --- | --- |
| 1 | Pull waste and linen | Empty trash | Pull trash |
| 2 | High dust | High dust, wash patient bed | Clean supplies |
| 3 | Damp wipe | Damp wipe furniture, spot walls | Fill supplies |
| 4 | Stock supplies | Bathroom cleaning | Sweep and spot mop floor |
| 5 | Clean bathroom | Stock supplies | (Mop thoroughly if necessary) |
| 6 | Damp mop floors | Damp mop floors |  |
| 7 | Inspect work | Inspect floors |  |

Read across the three columns and the pattern is the one you want in a cleaning business: a routine visit, a deeper turnover (your move-out or first clean), and a quick pass (your “tidy between visits” add-on), all built from the same steps. The rest of this guide translates it for homes and small commercial accounts.

## What are the 3 types of cleaning: cleaning, sanitizing and disinfecting?

The three types of cleaning are cleaning, which removes dirt and germs with detergent and water; disinfecting, which kills germs with chemicals; and sanitizing, which lowers germs to a safe level and can be done by cleaning, disinfecting or both. Most of a house clean is the first type. The second and third are specific steps on specific surfaces, and they only work after the first.

| Type | What it does | How | Where in a home or office |
| --- | --- | --- | --- |
| Cleaning | Removes dirt, dust, crumbs and germs; does not necessarily kill germs, but fewer remain | Detergent or all-purpose cleaner, water, cloths, agitation | Every surface, every visit |
| Sanitizing | Lowers germs to a safe level set by public health standards | Cleaning, a sanitizer at its label concentration and time, or a dishwasher cycle | Food-contact surfaces: counters, cutting boards, high chairs, dishes |
| Disinfecting | Kills germs on surfaces; does not necessarily clean a dirty surface | EPA-registered disinfectant left wet for its label contact time | Toilets, sinks, faucet handles, doorknobs, switches, phones, when the client asks or someone is ill |

Those definitions come from public health sources, not marketing. The Tennessee Department of Education’s [cleaning and disinfecting guidance for schools](https://www.tn.gov/content/dam/tn/education/health-&-safety/(c)Cleaning%20Guidance.pdf) states that cleaning works by using soap or detergent and water to physically remove germs, that disinfecting uses chemicals to kill germs but does not necessarily clean dirty surfaces, and that sanitizing lowers germs to a safe level by either cleaning or disinfecting. [MedlinePlus](https://medlineplus.gov/cleaningdisinfectingandsanitizing.html), from the National Library of Medicine, gives the same three definitions and adds that you usually need to leave a disinfectant on the surface for a certain time to kill germs.

The regulatory side matters for what you may claim. EPA’s page on [antimicrobial pesticides](https://www.epa.gov/pesticide-registration/what-are-antimicrobial-pesticides) defines disinfectants as products used on non-living surfaces to destroy or irreversibly inactivate infectious fungi and bacteria, and sanitizers as products that reduce, but do not necessarily eliminate, microorganisms to levels considered safe by public health codes. Both are registered pesticides. If your website says “we disinfect,” you are promising a registered product used by its label, not a spray of all-purpose cleaner.

## The seven cleaning procedure steps, adapted for a home

In a home, the seven steps run the same way: clear, high dust, wipe, restock, bathrooms, floors, inspect. Below is each step with what it covers, the tools and roughly what share of the visit it takes for a recurring clean.

1. **Pull waste and clutter (about 5%).** Empty every bin, replace liners, collect dishes to the sink, strip beds if linens are changing, pick up the floor so the vacuum can run. Spray the tub, shower and toilet now so the product can dwell while you do steps 2 to 4.
2. **High dust (about 10%).** Ceiling fans, light fixtures, tops of door frames, picture frames, curtain rods, the top of the fridge and cabinets, working toward the door. Dust falls; everything below gets done after.
3. **Damp wipe (about 25%).** Every horizontal surface and the handles, switches and fronts people touch: counters, tables, nightstands, cabinet fronts, appliances, remotes, door handles. Microfiber, lightly damp, folded in quarters, a fresh face each surface.
4. **Stock and reset (about 5%).** Make beds, fold towels the client’s way, refill soap and paper where you supply it, put the client’s items back where they were. In commercial work this is the dispenser round.
5. **Bathrooms (about 25%).** The product from step 1 has dwelled. Scrub shower and tub, clean the toilet inside and out including the base, sink, faucet, mirror, then disinfect the high-touch points at their contact time, then the floor last.
6. **Floors (about 20%).** Vacuum all floors (edges first, then open areas), then damp mop hard floors from the far corner toward the door. Dry before wet: never mop before the vacuum.
7. **Inspect (about 10%).** Walk every room the way the client will, from the doorway, with a phone light across surfaces. Photos of finished rooms, checklist signed, lights and locks per the access notes. Our [housekeeping checklist](https://broombook.com/guides/housekeeping-checklist) guide covers how a supervisor inspects the work.

The percentages are a planning split for a recurring clean in good condition, not a measurement; a first clean shifts time heavily toward steps 3 and 5. Our guide to the [deep cleaning checklist](https://broombook.com/guides/deep-cleaning-checklist) lists the extra tasks a first clean adds to each step.

## What are the steps for cleaning and sanitizing a surface?

Clean first, then sanitize or disinfect, and leave the product wet for the full contact time on its label. Spray-and-wipe, the habit most cleaners arrive with, skips the only step that does the sanitizing.

1. **Remove loose soil.** Crumbs, hair, dust. A disinfectant cannot reach a surface under debris.
2. **Clean with detergent.** All-purpose cleaner or soap and water, agitate with a cloth or brush, until the surface looks and feels clean.
3. **Rinse if the label says so.** Some disinfectants are deactivated by detergent residue; the label will tell you. Food-contact surfaces are usually rinsed.
4. **Apply the sanitizer or disinfectant.** At the dilution on the label, over the whole surface, not a light mist.
5. **Wait the contact time.** EPA’s guidance on [registered disinfectants](https://www.epa.gov/pesticide-registration/selected-epa-registered-disinfectants) defines contact time as how long the product must remain on the surface to be effective, says the surface should stay visibly wet for the entire contact time, and notes you may need to reapply to keep it wet. Tennessee’s school guidance gives a typical example of letting a disinfectant stand for 3 to 5 minutes, and EPA’s own example is a label contact time of 10 minutes.
6. **Wipe or air dry as the label directs.** Food-contact surfaces are usually left to air dry after a food-safe sanitizer; a toilet seat gets wiped dry.

### Where this goes wrong on real jobs

- Spraying the toilet seat and wiping it ten seconds later: cleaned, not disinfected.
- Using one cloth for the toilet and then the sink: moves germs from the dirtiest surface to the one people touch with clean hands.
- Diluting “a bit stronger to be safe”: off-label, can damage surfaces and does not shorten the contact time.
- Promising “sanitized” kitchen counters with an all-purpose cleaner that makes no sanitizing claim on its label.

Practical fix: in step 1 of the room, spray the toilet, sink handles and tub with the disinfectant; by the time you reach step 5 the contact time has passed. For a kitchen, clean the counters in step 3 and apply the food-safe sanitizer in step 4, then let it air dry while you do the bathroom.

## The food-service version: seven steps for a kitchen

Commercial kitchens use a different seven: scrape, rinse, apply detergent, rinse again, sanitize, rinse a final time, dry. If you clean restaurants, cafés or short-term rental kitchens, your team should know this sequence as well as the room sequence.

The Canadian Institute of Food Safety publishes it as a [seven-step cleaning and sanitizing poster](https://resources.foodsafety.ca/posters/7-steps-effective-cleaning-sanitizing) for food preparation areas (the poster names the steps; the notes after each are ours):

1. Scrape off food and debris.
2. Rinse (first time) with warm water.
3. Apply detergent and scrub.
4. Rinse (again) to remove detergent.
5. Sanitize with a food-safe sanitizer at its concentration and time.
6. Rinse (last time) only if the sanitizer label requires it.
7. Air dry; do not towel-dry a sanitized surface.

Health departments inspect food businesses against local codes, and the operator, not your cleaning company, holds the permit, so match the client’s written sanitation plan rather than inventing your own. Our [restaurant cleaning checklist](https://broombook.com/guides/restaurant-cleaning-checklist) lists the nightly, weekly and monthly tasks that sit around these seven steps.

## In what order should rooms and surfaces be cleaned?

Top to bottom, dry before wet, cleanest to dirtiest, and from the back of the home toward the door. Those four rules, applied in every room, are why the 7-step order looks the way it does.

- **Top to bottom.** High dust, then surfaces, then floors. Anything that falls lands on something not yet cleaned.
- **Dry before wet.** Dust and vacuum before you wipe and mop, or you make mud and streaks.
- **Clean to dirty.** Bedrooms and living areas before the kitchen; the kitchen before the bathrooms; in a bathroom, mirror and sink before the toilet. Cloths move in the same direction and never back.
- **Back to front.** Start in the room farthest from the exit so you never walk across a finished floor.
- **Around the room one way.** Pick clockwise or counter-clockwise and keep it, so nothing is skipped when the phone rings.

### Color-coding cloths to protect the order

A simple four-color system keeps step 3 and step 5 from contaminating each other: red for toilets and urinals, yellow for the rest of the bathroom, green for kitchens and food areas, blue for general surfaces. The colors themselves do not matter; using them every time does. Put the code on the checklist and in the caddy.

## Which chemical rules belong inside the process?

Four rules, printed on the checklist: never mix products, follow the label dilution, ventilate, and keep the safety data sheet for every product in the kit. The process is only as safe as the bottles in the caddy.

The Washington State Department of Health warns plainly: [do not mix bleach with ammonia, acids or other cleaners](https://doh.wa.gov/community-and-environment/contaminants/bleach-mixing-dangers). Bleach (sodium hypochlorite) mixed with ammonia produces chloramine gases, with symptoms from coughing and shortness of breath to chest pain, and it also reacts with drain cleaners and other acids. Many glass cleaners contain ammonia and many bathroom descalers are acids, so “bleach the toilet, then descale the tiles” in a small closed bathroom is a real-world version of that mix. One product at a time, rinse between, window open.

- **Label dilution only.** Measured, not splashed. Label a secondary bottle with the product name and the dilution.
- **Read the surface.** Bleach and acids damage natural stone, grout and some metals; the client’s marble counter is cleaned with a neutral product.
- **Gloves and ventilation** for every disinfectant and descaler, and eye protection when pouring concentrate.
- **Safety data sheets** in the van or on the phone for each product, and the same information when a client asks you to use their product.

Chemical handling and lifting are covered in more depth in our [housekeeping checklist](https://broombook.com/guides/housekeeping-checklist) guide. This is general information, not safety or legal advice; your state’s rules and the product label control.

## How do you train a team on the process and keep it running?

Teach the seven steps as a sequence first and a checklist second: a new cleaner shadows two visits, leads two with a trainer watching, then works alone with the checklist ordered the same way. After that, inspections and the checklist keep the order from drifting.

1. **Day 1: the why.** Walk a room and show what happens when the order breaks: dust on a wet counter, a mopped floor with footprints, a toilet wiped before the product worked.
2. **Days 2 and 3: shadow.** The trainer cleans, naming each step out loud; the new cleaner does steps 1, 2 and 4.
3. **Days 4 and 5: lead.** The new cleaner runs all seven; the trainer inspects at step 7 and scores.
4. **Week 2: alone, inspected.** Every job checked, same-day feedback.
5. **Ongoing:** the checklist for each home is written in step order, with the client’s named items in the step they belong to.

Build the checklist in the same seven blocks so the sequence is on the page. The free [cleaning checklist template](https://broombook.com/tools/cleaning-checklist-template) lets you order the tasks, add the client’s items and print a sign-off line. Broombook, which handles booking, scheduling and reminders for recurring service businesses, puts the same checklist on each cleaner’s phone with photo steps and clock-in, and keeps the client’s notes (products to avoid, the alarm, the dog) on the visit, so the step order and the home’s specifics arrive together; see [cleaning scheduling software](https://broombook.com/software/cleaning-scheduling-software) for how visits and checklists connect.

## Frequently asked questions

### What are the 7 steps of cleaning?

In the hospital environmental services method used by UNC Hospitals, the routine seven steps are: pull waste and linen, high dust, damp wipe, stock supplies, clean the bathroom, damp mop the floors, and inspect the work. The same order works in homes and offices: clear, high dust, wipe, restock, bathrooms, floors, inspect.

### What are the 3 types of cleaning?

Cleaning, sanitizing and disinfecting. Cleaning removes dirt and germs with detergent and water. Disinfecting kills germs with chemicals such as EPA-registered disinfectants. Sanitizing lowers germs to a safe level as defined by public health standards and can be done by cleaning, disinfecting or both.

### Should you clean or disinfect first?

Clean first. Dirt and grease stop a disinfectant reaching the surface, and public health guidance notes that disinfecting does not necessarily clean a dirty surface. Remove soil, clean with detergent, then apply the disinfectant and let it stay wet for the full contact time on its label.

### How long should a disinfectant sit on a surface?

As long as the label’s contact time, which varies by product and by the germ it is registered against. EPA says the surface should stay visibly wet for the whole time and may need reapplying. Tennessee’s school guidance gives 3 to 5 minutes as a typical example, and EPA’s own example is a label that requires 10 minutes.

### What are the steps for cleaning and sanitizing in a kitchen?

The food-service sequence is scrape, rinse, apply detergent, rinse again, sanitize with a food-safe sanitizer at its labeled concentration and time, rinse a final time if the label requires it, and air dry. Match the restaurant’s own written sanitation plan, since the operator holds the health permit.

### What order do professional cleaners clean a house in?

Top to bottom, dry before wet, cleanest room to dirtiest, and from the back of the home toward the exit. In practice: spray bathrooms first so product dwells, dust high, wipe surfaces, reset and restock, scrub bathrooms, vacuum then mop toward the door, and inspect.

### Can I mix bleach and other cleaners to clean faster?

No. Washington’s Department of Health warns that bleach mixed with ammonia produces toxic chloramine gases and that bleach also reacts with drain cleaners and other acids. Many glass cleaners contain ammonia and many descalers are acids. Use one product at a time, rinse between products and ventilate.
