The 9 Best Auto Trash Bags

Families who would rather wash a bag than keep buying new ones should start with the High Road TrashStash. A sealed waterproof lining holds wet cups and sticky wrappers, and a spring-loaded top stays open while you fill it, then pushes shut over the mess. A buckle strap wraps a headrest or a center console, or the bag sits on the floor. The lining doesn't come out, so a spill has to be wiped clean inside the bag.

Without spending much, the EPAuto Waterproof gets you a lidded soft bin with a sealed vinyl lining that wipes or rinses clean. Trash goes in through a stretchy round hole in the lid, which keeps the mess out of sight. Pockets on three sides hold wipes and napkins, and grip pads underneath keep it from sliding. The lining is sewn in, so unless you add a small bag inside, emptying it means turning the whole bin over.

Rideshare drivers and parents who never want to scrub a bin can hang Tossits Hanging Bags and throw the mess away. Each bag comes on its own hanger that loops over a headrest post or gear shift, then tears off along a perforated line when full. The maker says the plastic is recycled and can be recycled again. Restocking gets pricey, and a full bag can rip off its hanger if you pull it sideways instead of straight down.

A busy family car can fill a bag a day, and Enlivik Disposable Bags come 50 to a flat dispenser that hangs from a headrest cord or sticks to a hard surface. When one is full, you tear it along the line and fold a sticky strip over the top to seal in smells. The maker has changed the cord and the tear strip more than once in a short time, which hints that early packs had trouble.

Small cars and front seats are where the High Road Small fits best. It's a slim pouch with a vinyl lining that hangs flat against a seat back, shifter or door handle on a hook-and-loop strap, so it barely touches anyone's leg room. A mesh pocket on the front holds tissues or hand cleaner, which keeps them in reach of the driver. It holds about three quarts, so a single fast-food meal can fill it.

The UTSAUTO Washable 2-Pack gives you two cloth sleeves, one for each side of the back seat, so nobody has to pass trash forward. Each buckles onto a headrest, and the bottom opens with a hook-and-loop flap to dump straight into a bin, which beats digging wrappers out of the top. The cloth resists drips but has no waterproof lining, so a spilled soda can soak through, and each sleeve is on the small side.

For carsick kids or a quick spot near the driver, RuGuo Stick-On Bags press onto a dashboard, door panel or console with a sticky back strip. The pack holds 60 in bright cartoon prints, and each one seals after use. They hold only on clean, smooth plastic or glass; on cloth seats the glue lets go. Keep the thin plastic away from babies and toddlers, since any film bag can smother a small child.

Car sickness calls for a bag that won't flop over, and KeenEcho Stand-Up Bags sit upright on a console or floor without help. The film is heavier than typical car litter bags, and the maker says nearly a third of it is recycled plastic. A sticky edge can hold one to a surface and closes it when you're done. Each one is small, so it suits a single mess rather than a day of road-trip trash.

If you already own a car trash can, Hefty Small Drawstring Bags make a cheap, sturdy liner so the can itself stays clean. The drawstring ties shut for the walk to the curb, and the box holds 52. They carry an ocean scent with Arm & Hammer odor control, which helps in a closed-up car. They're sized for home wastebaskets, though, so the top can bunch up over a small car bin, and the scent isn't for everyone.
