To clean the hardshell luggage, warm water and soap used with a soft cloth or sponge will do the trick. To avoid any marks, rinse off your suitcase thoroughly before letting it dry. For softshell luggage, use a gentle soap diluted with water and a soft sponge to get out any marks. After rinsing off, it is recommended to use a hairdryer on a low setting to speed up the drying process.
