Tony Wang10 min readPrivate Equity Has Been Buying Car Washes for Years. Most of the Industry Still Isn't Theirs.
We mapped 44,043 US car washes. The 10 biggest PE-backed chains combine for just 21% of listings — and the flagship one, Zips, went through bankruptcy in 2025.
Car washes have had a specific reputation in business press for years now: a fragmented, cash-generating, real-estate-adjacent industry that private equity discovered and started buying up, chain by chain, roughly since 2018. That story is accurate as far as it goes. What it leaves out is scale — and, more recently, what happens when a leveraged roll-up model meets a capital-intensive business with long-dated returns.
The roll-up is real. It's also still a small fraction of the market.
| Chain | Share of a 500-record national sample |
|---|---|
| Circle K (gas-station-attached washes) | 3.6% |
| Club Car Wash | 2.8% |
| Mister Car Wash | 2.4% |
| WhiteWater Express | 2.0% |
| Tidal Wave Auto Spa | 1.8% |
| GO Car Wash | 1.6% |
| Rainstorm Car Wash | 1.6% |
| Take 5 Car Wash | 1.4% |
| Blue Beacon (truck washes) | 1.4% |
| Tommy's Express | 1.0% |
| Top 10 combined | 21.0% |
| Independent / other (320 unique domains in sample) | 79.0% |
That 21.0% roughly matches independent industry estimates: trade sources put the top 50 conveyor (express tunnel) chains nationally at around 4,350 locations, or 6-7% of the estimated 60,000-70,000 US car wash fleet — and separately estimate that around 71% of US car wash operators are independent, with roughly 3,000 companies running just one or two locations each. Both readings point the same direction: PE-backed consolidation in car washes is a real, ongoing trend, and it has not come close to remaking the industry's basic shape the way it has in, say, self-storage or hotels.
Zips Car Wash: a bankruptcy that didn't touch the physical footprint
We checked what this looks like in live location data: q="Zips" within category=car_wash returns 263 listings across the country — a close match to the 260+ locations across 23 states that trade press reported Zips operating at the time of its filing. That's the key detail this kind of restructuring story can obscure: Chapter 11 with a debt-for-equity swap is a financial event, wiping out the sponsor's ownership stake and handing the company to its lenders, not necessarily a store-closure event. Zips' physical business — the locations customers actually drive their cars into — appears to have survived the process largely intact.
Three more brands, cross-checked against independent counts
| Chain | Live listing count | Cross-check |
|---|---|---|
| Mister Car Wash | 553 | q="Mister", 9/10 sampled genuine (1 unrelated "Mister Suds" business) |
| Zips Car Wash | 263 | q="Zips"; matches 260+ reported at Feb. 2025 bankruptcy filing |
| Tommy's Express | 263 | q="Tommy's"; matches ~243-270 US locations reported independently |
| WhiteWater Express | ~145 | q="Whitewater", 7/8 sampled genuine (1 unrelated small independent business) |
Mister Car Wash is itself a story about the limits of the PE roll-up thesis: the company went public via IPO, giving its PE backers a proof-of-concept exit, and has more recently gone private again — trade coverage describes analysts struggling to underwrite "a leveraged roll-up model layered onto a capital-intensive base with long-dated return realization." That's a more measured, harder-fought version of the growth story than "PE floods a fragmented industry and wins."
A different kind of category conflation: gas-station-attached washes
Per-capita density: the same pattern, one more time
| Rank | State | Listings | Per 100k residents |
|---|---|---|---|
| 1 | North Dakota | 196 | 24.61 |
| 2 | South Dakota | 224 | 24.22 |
| 3 | Iowa | 694 | 21.41 |
| 4 | Nebraska | 384 | 19.15 |
| 5 | Arkansas | 551 | 17.84 |
| 6 | Alabama | 901 | 17.47 |
| 7 | Louisiana | 803 | 17.47 |
| 8 | Texas | 5,341 | 17.07 |
| 42 | Idaho | 191 | 9.54 |
| 43 | New Jersey | 906 | 9.54 |
| 44 | Utah | 325 | 9.28 |
| 45 | New York | 1,647 | 8.29 |
| 46 | Arizona | 610 | 8.04 |
| 47 | Massachusetts | 568 | 7.96 |
| 48 | Washington | 624 | 7.84 |
| 49 | Oregon | 283 | 6.62 |
This is now the fifth time this exact rural-density pattern has shown up in this series, after bank branches, credit unions, hotels/motels, and self-storage. We're noting it for completeness rather than treating it as new: sparsely populated states support more physical locations per resident than dense ones can with a smaller, more centralized footprint.
How we did this, and the caveats
Every number above comes from a live search/facets call against Crawlora's Google Maps business dataset, 2026-08-27 snapshot, cross-referenced against US Census Bureau Vintage 2025 (July 1, 2025) state population estimates and independently sourced trade press and bankruptcy filing coverage.
| What | Detail |
|---|---|
| Per-capita ranking | category=car_wash, 44,043 US listings across 49 states |
| Chain-penetration | 500-record national sample (has_website=true, sort=updated_at_desc, deduplicated), classified by website domain |
| Individual brand verification | Single-word q= searches for Mister, Zips, Tommy's, and Whitewater, each sample-checked for contamination, cross-referenced against independently reported location counts |
| Zips bankruptcy facts | Sourced independently from bankruptcy court filings and trade/legal press coverage, not derived from the Google Maps dataset |
Caveats worth stating plainly: the 21.0% top-10 figure is a sample-based relative comparison, not an exhaustive census of 44,043 listings — a different 500-record sample would move individual brand shares by a point or two, though it lines up well with independently reported industry-wide concentration figures. We verified 4 of the top 10 domains against independent location counts and found all 4 consistent; the other 6 (Circle K, Tidal Wave, GO Car Wash, Rainstorm, Take 5, Blue Beacon) were not individually cross-checked the same way, so treat their specific shares with the same "relative, not absolute" caveat as the rest of this series' chain-penetration figures. This measures physical locations, not revenue, membership subscriber counts, or wash volume — a car wash's PE valuation is typically driven by recurring membership revenue, which this dataset can't measure directly. Blue Beacon in our sample is specifically a truck wash chain, a different customer segment from passenger-vehicle car washes, included here because it shares the same category tag. And as with every study on this dataset: it's live-growing, and car wash ownership continues to shift through further M&A and, as Zips shows, restructuring — a re-pull months from now will likely show a different picture.
If you want to run your own consolidation or density checks on this data, that's exactly what Crawlora's Google Maps business API is for — the same structured-data approach behind our self-storage REIT consolidation, hotel chain consolidation, and bank branch density studies.

Frequently asked questions
How much of the US car wash market has private equity actually consolidated?
Less than trade press coverage might suggest. A 500-record national sample classified by website domain found the top 10 chains combining for just 21.0%, against 320 unique domains in the same sample. That roughly matches independent industry estimates that the top 50 conveyor chains nationally hold only about 6-7% of the 60,000-70,000 US car wash fleet, with roughly 71% of operators still independent.
What happened to Zips Car Wash and is it still operating?
Zips filed Chapter 11 bankruptcy on February 5, 2025, cutting about $279 million in debt through a debt-for-equity swap. Its financial sponsor, Atlantic Street Capital, had its equity cancelled entirely, and the lender group took 100% ownership of the reorganized company. It emerged from bankruptcy on April 30, 2025. Live Google Maps data shows 263 Zips locations currently operating, closely matching the 260+ locations across 23 states reported at the time of filing — the bankruptcy was a financial restructuring, not a store-closure event.
Why can't you just search 'Mister Car Wash' or 'Club Car Wash' to count their locations?
Because the phrase 'Car Wash' is embedded in nearly every listing's name within category=car_wash, so a two-word brand query gets contaminated by that shared text. q='Mister Car Wash' and q='Club Car Wash' each return roughly 16,500 results — about a third of the entire national category. Dropping to a single distinctive word instead (q='Mister', q='Zips', q='Tommy's') gives clean, verifiable counts that match independently reported location figures.
Are Circle K and BP car wash companies?
No — they're convenience-store and gas-station chains whose locations frequently include an attached car wash bay. Circle K (owned by Alimentation Couche-Tard) was the single largest domain in our sample, ahead of every dedicated PE-backed car wash chain, because gas-station-attached washes get the identical category=car_wash tag as standalone destination car washes, even though it's a structurally different kind of business.
Which US state has the most car washes per capita?
North Dakota, at 24.61 car washes per 100,000 residents, followed closely by South Dakota. Oregon is last at 6.62 per 100k. This is the fifth time in this data series the same rural-density pattern has appeared, after bank branches, credit unions, hotels/motels, and self-storage facilities.
