I ditched the chemicals, grabbed a pile of filthy floor mats, and let steam do the talking. Here's what happened when we put the latest trend in car cleaning to the test.

The right steam cleaner can also refresh carpets and cloth upholstery, loosen stubborn buildup in tight crevices, and sanitize frequently touched surfaces. While steam isn't a replacement for regular cleaning and maintenance, it's one of the most versatile detailing tools you can own. Many models are just as useful around the house, making them a worthwhile investment whether you're cleaning your everyday ride or prepping your SUV for a big summer road trip.

That means you can tackle grease, sticky residue, soda stains, and everyday messes throughout your vehicle. You'll be using fewer chemicals, making it a great option for routine interior maintenance. Steam is especially effective on hard plastics, rubber trim, cup holders, air vents, and other areas that are difficult to scrub by hand.
While I know a lot about what goes into cleaning a vehicle and keeping it clean, I thought it would be best to phone my buddy Larry Kosilla, founder of Ammo NYC, to get his take on if, when, and how to use steam cleaners for your car or truck.
On paper, the Dupray Neat is just another household steamer; it's a compact, pressurized cleaning machine designed to tackle household messes and your vintage brocade upholstery. While I'm sure it can handle those sorts of jobs with ease, I can imagine dozens of jobs around my garage that are perhaps better suited for the Neat's 275-degree steam temperature and 50 minutes of run time.
Out of the box, the unit feels premium, thanks in part to its Apple-esque minimalism and cube-shaped design. It's surprisingly portable thanks to its neat retractable handle. The rolling base is sturdy, and the lengthy hose has a reassuring flexibility. It comes with an extension tube, a floor tool with microfiber pads, a triangular tool for corners, a window squeegee, multiple nylon and brass brushes, and even a lance for precision blasting. It's a full detailing and household kit in one package, without having to buy extras. My one gripe: there's no water level indicator, so you're topping it off by faith until you learn the system.
To test it, I went after a couple of old floor mats I've collected from various cars that have come and gone over the years, and a cloth seat out of an early Saab 900 darkened with years of rear-end filth. After filling, the unit took about six minutes to heat up, and as soon as the indicator light turned green, the Neat produced a powerful stream of dry steam. On harder surfaces, like a rubber floor mat, it loosened some (but not all) of the built-up dirt enough that it could simply be wiped away with a rag, without the need for chemical sprays.
I appreciated the length of the hose and power cord, which made it easy to maneuver around a car without constantly dragging the unit along. The safety cap is a smart bit of idiotproofing; you can't open the tank while it's under pressure, and the fact that it runs on plain tap water keeps running costs at essentially zero.
I didn't love the lack of onboard storage for accessories, and the heat-up time of around seven minutes feels slow when you're ready to get to work. But once the unit is fully running, the continuous steam flow more than makes up for it. At just under $200, this option is neither the cheapest nor the priciest, though buying extra pads and attachments can push the cost north quickly.
For anyone who details their car regularly, maintains multiple vehicles, or just wants a chemical-free way to keep their interior clean, the Dupray Neat is an excellent choice.
