A June study by travel insurance company InsureandGo revealed that the wheels, handles, and bottoms of suitcases harbor the most bacteria. Microbiologist Amy-May Pointer points out that the wheels on suitcases can carry 58 times more bacteria than a public toilet seat.

This is because wheels are constantly in contact with sidewalks, bathroom floors, and other unclean surfaces during travel. The bottom of the suitcase is equally dirty. Studies by Pointer indicate that black mold can easily cling to this area.

To keep suitcases clean, experts recommend placing them on luggage racks in hotels instead of on the floor or bed. If the hotel room doesn't have a luggage rack, travelers can use plastic shower caps to cover the wheels, preventing the spread of bacteria to carpets and bedding.

If possible, avoid pulling suitcases through puddles or dirty areas. The less contact with dirt, the cleaner the suitcase.

Travelers should also wash their hands after handling their suitcases, as handles can easily become contaminated during the trip. "Treat it like you've just touched a toilet seat, because effectively, you have", says Pointer.

Upon returning home, travelers should wipe their suitcases with disinfectant wipes or soapy water. Soaking the wheels in warm, soapy water is also recommended. Hard-shell suitcases can be cleaned with a mild bleach solution. For fabric suitcases, vacuuming or scrubbing with baking soda can remove mold.
