Dirty Car Survey
· ·

Okay, Some of Y’all are Just Plain NASTY

As an Editor for several venues, I see a good bit of Press Releases and Media Alerts for cool startups, health & beauty sites, upcoming books and movies, and on and on. While a lot of that is really cool to be on the “inside” of, some of the more fun stuff that comes across my desk tends to be unexpected web series, podcasts, and really surprisingly, surveys.

And this one is no exception.

You can see their methodology at the end of this release and before we get to their findings, I have two things to say and one question.

Statement 1 – Some of y’all are indeed NASTY!

Statement 2 – Never marry a man with a red car!

Question – How, in the name of all things Holy, are so damn MANY of you peeing in bottles?

Anyway, check out what this survey found about the kinds of crap people are leaving in their cars, and which car owners are the most guilty.


  • Old tissues are the number one item people leave in their car with 39.1% admitting to this!
  • 32.2% of people are guilty of leaving a PEE bottle in their car!
  • When it comes to cleaning their cars 11.7% admit to NEVER doing so!
  • RED car owners have the messiest cars, with 33.5% of people never cleaning theirs!
  • Shockingly, 1 in 10 (10.3%) have left used condoms and 8% have left used sanitary items in their car!

It’s easy to get swept up in the day-to-day chaos. Maintaining order in our lives can be taxing and so keeping up with the mess that accumulates in our car is not a priority. 

This inspired EOT Cleaning to ask the question; what are some of the grossest things people have kept in their car?

They surveyed 3,230 people from across globe, asking them ‘What are some of the grossest things you have had in your car that you may have forgotten about

We’ve all been guilty of leaving McDonalds remnants in the car from time to time, but with most people (41.7%) only cleaning their car every six months, it begs the question; how long has that food been sitting there?
