No, you should generally avoid putting car mats in a washing machine. While it might seem like a quick and easy cleaning solution, the machine can damage both the mats and your appliance. The agitation and spin cycles can cause rubber mats to deteriorate and crack, while fabric mats can shrink, fray, or lose their shape. Furthermore, the heavy dirt, gravel, and debris embedded in the mats can damage the washing machine's drum.
The correct cleaning method depends entirely on the mat's material. For all-weather rubber or vinyl mats, the best approach is to remove them from the car, shake off loose dirt, and scrub them with a stiff brush, soapy water (using a mild detergent like dish soap), and a hose. For carpeted fabric mats, vacuum thoroughly first, then use a carpet cleaner or upholstery shampoo with a scrub brush, followed by a thorough rinse. A key step for both types is to allow them to air dry completely before reinstalling them to prevent mildew.
The table below compares the risks and proper cleaning methods for the two main types of car mats.
| Mat Material | Washing Machine Risk | Recommended Cleaning Method | Key Drying Tip |
|---|---|---|---|
| Rubber/Vinyl | High: Can become brittle, crack, or deform. | Remove, shake, scrub with brush/soapy water, hose off. | Air dry in the sun; wipe underside to prevent moisture trap. |
| Carpeted Fabric | Very High: Likely to shrink, fray, or retain water. | Vacuum, pre-treat stains, use upholstery cleaner, scrub, rinse. | Air dry completely; use a wet/dry vacuum to extract excess water. |
| TPE/Advanced Polymer | Moderate-High: May withstand gentle cycle, but risk remains. | Similar to rubber mats; hand wash is always safest. | Air dry thoroughly. |
| Factory Carpeted (with backing) | Extreme: Waterlogging can ruin backing, causing mold. | Avoid soaking; use professional interior cleaning methods. | Critical to use a wet/dry vacuum and dry in a well-ventilated area. |

Trust me, I learned the hard way. Tossed my fabric mats in the wash to save time, and they came out shrunken and bunched up. They never fit right again. Now I just pull them out, give them a good vacuum, and spot clean any stains with a little carpet cleaner. For the rubber ones, a quick scrub with the hose and some dish soap does the trick. Air drying is the most important part—no one wants that mildew smell.

As a detailer, I'd never recommend a washing machine. The goal is to clean without causing damage. The abrasive dirt can scratch your machine's drum. Instead, beat the mats to remove loose debris. For rubber mats, use a dedicated all-purpose cleaner and a stiff brush. For carpet, an upholstery tool on a wet/dry vacuum is ideal. Proper technique preserves the mats and your appliance, giving you a professional-level clean at home.

Check your car’s owner’s manual. Many manufacturers explicitly advise against machine washing mats, and doing so could void your interior warranty if damage occurs. The mats are designed for specific cleaning methods. The high heat and harsh spin cycles can break down the materials prematurely. It’s always safer to follow the manufacturer’s recommended cleaning procedure, which is typically a simple hand wash, to ensure your mats last as long as your car.

Think about what’s trapped in those mats: road salt, oil, tiny pieces of gravel. You don’t want that gunk circulating in your washing machine, potentially clogging it or leaving a residue on your next load of clothes. It’s a contamination risk. The five minutes you save isn't worth a potential repair bill. Taking the extra time to clean them by hand outside is not only better for the mats, but it’s also better for your appliance.
