A compiled reference of 34 verified statistics on store cleanliness: what customers say it does to their behavior, what it measurably does to revenue, what blind audits show real store conditions look like, restroom-specific data, and the hotel and rental evidence. Every figure is drawn from a named public source (Ipsos, FMI, Cintas and The Harris Poll, ServiceChannel, Steritech, Bradley, Tork by Essity, Ecolab, peer-reviewed journals including Science and the Quarterly Journal of Economics) and independently checked before publishing. The widely repeated cleanliness claims that could not be traced to any source are documented separately, with what we found when we tried.

Key statistics
Key takeaways
Cleanliness is the most-valued observable trait of a store, it moves real revenue when customers can see it, disorder compounds itself, and inspection cadence measurably improves conditions. Meanwhile, the most-quoted numbers in the cleaning industry's own marketing have no sources.
A clean, neat store is the #1 thing grocery shoppers value: 73% call it very or extremely important.
64% have left a store over its physical condition; only 20% ever left over missing tech.
Posting hygiene grades raised A-grade restaurant revenue 5.7% and cut C-grade revenue 1%.
In Science-published field experiments, visible disorder doubled littering and theft.
Inspection cadence works: 4 assessments a year yields up to 1.5x fewer findings than 1.
The famous "92% will never return" stat has no source; the real 92% says something different.
How we built this report
Every figure was compiled in August 2026 from named public sources and verified against the original document, press release, or paper before publishing.
- Primary surveys with methodology
Preference went to sources that disclose sample sizes and field dates: Ipsos (n=1,008), FMI (n=2,023), Cintas/Harris Poll waves (n=1,004-2,034), Bradley (n=1,020, run annually since 2009), Tork/Essity (n=11,500 across 11 countries).
- Audits over opinions where possible
Steritech's blind assessments (450,000+ across 30 brands) measure what conditions actually are, not what customers say; they anchor the operator-side section.
- Peer-reviewed causal evidence
The revenue and disorder findings come from the Quarterly Journal of Economics, Science, and Frontiers in Psychology, not vendor decks.
- Independent review
Written by one co-founder, reviewed by the other before publishing.
Scope caveats: consumer-survey figures are self-reported sentiment, not observed behavior; several strong sources are vendor-commissioned (Cintas, Tork, Ecolab sell cleaning products and services) and are named so readers can weigh that. Years are stated inline, and the oldest heavily-quoted wave (Cintas/Harris, fielded December 2010) is flagged as such wherever it appears.
Store cleanliness, by the numbers
34 verified figures in six themes, ordered as a causal chain: customers notice, behavior changes, revenue follows, disorder compounds, real conditions measured, and cadence fixes it.
Customers notice, and rank it first
According to FMI's U.S. Grocery Shopper Trends 2026 research with The Hartman Group (fmi.org; 2,023 respondents fielded February 2026, with the headline figure reported by Grocery Dive), a clean, neat store is the number one characteristic shoppers value. According to Ipsos polling for P&G Professional (ipsos.com; n=1,008, June 2017), 92% of Americans say cleanliness matters to whether they become repeat customers. And the most complete ranked inventory of what customers notice comes from Cintas with Harris Interactive (cintas.com; n=1,004, fielded December 2010, the oldest wave used here).
Statistic 1
73% of grocery shoppers say a "clean, neat store" is very or extremely important, the #1 characteristic they value in stores.
FMI U.S. Grocery Shopper Trends, as reported by Grocery Dive (2026)
Statistic 2
92% of Americans say the cleanliness of a business is an important factor in deciding whether to become repeat customers.
Ipsos for P&G Professional, n=1,008 (2017)
Statistic 3
99% of US adults said any poor cleanliness issue would negatively affect their perception of a retail store.
Cintas / Harris Interactive, n=1,004 (fielded December 2010)
Statistic 4
Cleanliness ranked second only to food quality among supermarket experience factors (4.40 vs 4.45 on a 5-point scale), ahead of staff friendliness, checkout speed, and value for money.
Retail Feedback Group, n=1,200 (2017)
Statistic 5
All six top-rated US grocers in Consumer Reports' 96-chain member survey (75,000+ members, 140,000+ store visits) scored high on cleanliness; cleanliness had "a large impact" on overall store opinion.
Consumer Reports grocery ratings (2019)
What this means: across every methodology, from a 2,000-person 2026 survey to a 140,000-visit ratings panel, cleanliness lands at or near the top of what customers evaluate. It is the most legible operational quality a store has.
Noticing changes behavior
According to ServiceChannel's State of Brick and Mortar Retail report (servicechannel.com; 1,521 consumers, 2019), the walkout numbers are concrete, and the comparison the industry always misses is the technology one.
of shoppers have left a store because of its physical appearance or disorganization.
have ever left a store because it lacked a specific technology. Condition beats tech 3-to-1.
Statistic 6
69% of shoppers are less likely to return after a negative in-store experience; 43% become more likely to shop at a competitor; 40% will spend less money and time in the store.
ServiceChannel, 1,521 consumers (2019)
Statistic 7
Four out of five shoppers would rather have a clean store than the newest in-store technology; 70% endured a negative in-store experience in the prior six months.
ServiceChannel (2019)
Statistic 8
74% of Americans say dirty restrooms make them view a business negatively, 68% say the same of dirty floors, and over half are influenced by dirty entryways (57%), visible dirty mops (56%), dirty windows (51%), and poorly maintained parking lots (51%).
Cintas / The Harris Poll, 2,000+ US adults (2021)
Statistic 9
Cleanliness sensitivity rises steeply with age: 56% of 18-34s say dirty restrooms sour them on a business, versus 92% of adults 65 and older.
Cintas / The Harris Poll (2021)
Statistic 10
53% of consumers call cleanliness and store ambiance a crucial factor in choosing a convenience store, up from 43% one year earlier; 70% say overall cleanliness influences whether they believe the food is fresh.
Intouch Insight c-store research (2024-2025)
What this means: customers use visible condition as a proxy for everything they cannot see, including food freshness, and the effect is strengthening year over year, not fading.
Behavior shows up in revenue
The strongest evidence on this page is causal, peer-reviewed economics. When Los Angeles County introduced restaurant hygiene grade cards, economists Ginger Zhe Jin and Phillip Leslie matched confidential sales-tax records for every restaurant in the county, 1996-1998, to health-inspection scores; their findings were published in the Quarterly Journal of Economics and summarized by the authors in Choices magazine (choicesmagazine.org). Cleanliness had no revenue effect until it became visible; then it did.
Statistic 11
After hygiene grade cards were introduced, A-grade restaurants' revenue rose 5.7% and C-grade revenue fell 1%, relative to the no-card baseline.
Jin & Leslie, Quarterly Journal of Economics research, via the authors' Choices summary (2003-2005)
Statistic 12
The same grade-card introduction corresponded to a 20% decrease in food-illness hospitalizations (a finding later academically contested on magnitude, which we note in fairness).
Jin & Leslie (2005); magnitude disputed by later Stanford work
Statistic 13
A one-star rating increase leads to a 5-9% revenue increase for independent restaurants, per regression-discontinuity analysis of Yelp ratings against Washington State revenue records.
Michael Luca, Harvard Business School working paper (2011, rev. 2016)
Statistic 14
A 5-point cleanliness score improvement corresponded to an estimated $506.12 more in weekly sales per restaurant, about $26,318 a year, in a correlational analysis of 4,000 client assessments matched to sales.
Steritech assessment analysis (2024; correlational, vendor-owned data, stated as such)
Statistic 15
Cleanliness is the strongest single driver of dissatisfaction in short-term rental reviews: across 59,766 Airbnb reviews in 12 cities, a dirty or smelly environment was the most likely driver of user dissatisfaction.
Ding et al., Frontiers in Psychology, peer-reviewed (2021)
What this means: the Jin and Leslie result is the thesis of this whole page: hygiene only moved revenue once customers could see a grade in the window. Cleanliness pays in proportion to how observable and verifiable it is.
Disorder compounds itself
In randomized field experiments published in Science (science.org) by Keizer, Lindenberg, and Steg (2008), visible disorder measurably caused more disorder, including theft, and one experiment ran literally in a supermarket parking lot.
Statistic 16
Unreturned shopping carts in a supermarket lot raised littering from 30% to 58% of passersby (p=0.002).
Keizer, Lindenberg & Steg, Science (2008)
Statistic 17
Visible graffiti more than doubled littering (33% to 69%, p<0.001), and visible disorder roughly doubled theft of a visible envelope containing money: 13% stole it in the orderly condition, 27% with graffiti present, 25% with litter present.
Keizer, Lindenberg & Steg, Science (2008)
What this means: condition is not cosmetic. A messy store statistically invites more mess and more loss, which connects cleanliness directly to the shrink line covered in our companion report on retailer disclosures.
What conditions actually look like, measured blind
According to Steritech (steritech.com), the Rentokil-owned assessment firm whose convenience-store report draws on 450,000+ blind and revealed assessments across 30 brands, measured reality is rougher than survey sentiment, and inspection cadence is the lever that moves it.
Statistic 18
In a blind assessment of 80 convenience stores across 5 national and regional brands, 23% of locations were missing soap and paper towels.
Steritech blind assessment study (2022)
Statistic 19
Convenience stores average about 150% more cleanliness findings than quick-service restaurants, across analyses of 450,000+ assessments and 4.5 million findings.
Steritech assessment analyses (2024)
Statistic 20
Peak improvement occurs at 4 assessments per year: up to a 1.5x reduction in total findings versus locations assessed once annually.
Steritech, 35+ years of assessment programs (2024)
Statistic 21
The vertical inspected less often is the dirtier one: QSRs average 2.66 assessment visits a year, convenience stores 1.92.
Steritech (2024)
Statistic 22
Store conditions degrade through the shopping day: supermarket satisfaction averaged 4.42 before 3 p.m. versus 4.36 after, in a 1,200-shopper panel.
Retail Feedback Group (2017)
What this means: observation frequency, not policy, is the operational lever: the audited difference between one look a year and four is up to 1.5x fewer problems. That is the same argument, made by a pest-control-owned audit firm's data, that continuous photo-based review of every location makes structurally.
Restrooms, hotels, and rentals
Restrooms are the single most-studied cleanliness surface. According to Bradley Company's annual Healthy Handwashing Survey (bradleycorp.com; n=1,020, fielded January 2026, running since 2009), 86% of Americans expect a business's restroom quality to reflect the quality of its goods and services. According to Tork by Essity (torkglobal.com; 11,500 respondents across 11 countries), the expectation-versus-delivery gap is stark. And in lodging, Ecolab's annual consumer study (ecolab.com; n=508, September 2024) puts cleanliness at the top of both good and bad reviews.
Statistic 23
68% of Americans are more likely to return, and spend more, at businesses with clean, well-maintained restrooms; 73% say an unclean restroom makes them think twice about returning; about 40% check the restroom before deciding to do business at all.
Bradley Healthy Handwashing Survey (2026)
Statistic 24
74% of people expect moderate or high hygiene in public restrooms, but only 20% of restrooms deliver on those expectations; 52% change their behavior after a poor restroom experience (28% spend less time, 23% limit eating and drinking, 11% warn friends, 7% leave bad reviews).
Tork by Essity, 11,500 respondents, 11 countries (2025)
Statistic 25
US venues most likely to fail restroom expectations: convenience stores (30%), transit stations (25%), and shopping malls (25%).
Tork by Essity (2025)
Statistic 26
97% of US adults would be influenced not to return to a restaurant over a facility issue; top drivers are dirty surfaces (86%), bad odor (85%), dirty restrooms (80%), and dirty or slippery floors (72%).
Cintas / The Harris Poll, n=2,034 (2016)
Statistic 27
60% of consumers rank guest-room cleanliness among the top three factors in a positive hotel experience, and room cleanliness is the #1 reason guests leave both positive and negative reviews; cleanliness is the #3 hotel-selection factor behind only price and location, for the third straight year.
Ecolab Hotel Cleanliness Consumer Study, n=508 (2024)
Statistic 28
76% of consumers would be disappointed if a third-party hotel inspection did not verify that high-touch areas are sanitized; demand is for verified cleanliness, not just clean-looking rooms.
AAA inspection program research (2021; survey methodology not fully disclosed, noted)
What this means: the restroom is the store's reputation in miniature (86% read it as a proxy for the whole business), and in lodging cleanliness is both the top review driver and, chained to the one-star-equals-5-9%-revenue finding above, a direct revenue variable.
Famous cleanliness claims with no source
The cleaning industry's most-quoted statistics circulate on thousands of janitorial websites. We traced each to its most-original surviving document; these failed, and this section exists so writers can stop repeating them.
"92% of customers will never return to a dirty store."
Unsourced. No study, sample, or year exists anywhere; sites cite each other in a loop. It appears to be a garbled restatement of the real Ipsos/P&G finding that 92% call cleanliness an important factor in repeat custom, which is a much weaker claim.
"95% of shoppers say exterior appearance influences where they shop."
Unsourced. Attributed to nothing, anywhere. The verified replacements are Cintas 2021's exterior figures: dirty entryways 57%, dirty windows 51%, poorly maintained parking lots 51%.
"The correlation between cleanliness scores and sales is 0.82333."
Fabricated precision. Steritech's own report describes "a very strong correlation" and publishes dollar figures, but no coefficient. Someone added five decimal places to a sentence. Use the real finding: 5 points of cleanliness ≈ $26,318 a year per location, correlational.
"One cleaning complaint costs $3,000" / "95% of guests mention cleanliness in reviews."
Fabricated. These circulate in vacation-rental vendor blogs citing "industry research" that does not exist. The peer-reviewed replacement: across 59,766 Airbnb reviews, a dirty environment was the single strongest dissatisfaction driver (Frontiers in Psychology, 2021).
"Slip-and-fall injuries cost businesses $70 billion a year (NFSI)."
Two-decade-old figure with no published methodology. The National Floor Safety Institute's quick-facts page no longer resolves and its figures carry loose attributions. The defensible modern numbers are federal, and they live in our companion report on retail slip-and-fall statistics.
What this means: the cleaning industry markets itself with numbers nobody can defend, while the verified evidence, which is stronger than the folklore, goes uncited. Everything above this section survives a source check.

Quick FAQ
How does store cleanliness affect sales?
Causally, when it is visible: Los Angeles hygiene grade cards raised A-grade restaurant revenue 5.7% and cut C-grade revenue 1%, based on county-wide tax records (Jin and Leslie, Quarterly Journal of Economics research). Correlationally, Steritech's 4,000-assessment analysis puts a 5-point cleanliness score gain at about $26,318 a year per location.
What percentage of customers leave a store because it is dirty?
64% say they have left a store over its physical appearance or disorganization, versus 20% who ever left over missing technology (ServiceChannel, 2019). The circulating "92% will never return" figure has no traceable source.
Do dirty restrooms really cost businesses customers?
The evidence says yes: 73% think twice about returning after an unclean restroom, 86% read restroom quality as a proxy for the whole business (Bradley, 2026), and globally only 20% of restrooms meet hygiene expectations while 52% of people change their behavior after a bad restroom experience (Tork by Essity, 11,500 respondents).
Does more frequent inspection actually make locations cleaner?
Measurably: Steritech's assessment data across 35+ years shows peak improvement at 4 assessments a year, with up to 1.5x fewer findings than annually-assessed locations, and the vertical that gets inspected less (convenience, 1.92 visits a year vs QSR's 2.66) runs about 150% more cleanliness findings.
