After I have emptied the Smartwastebag over the garbage can, I turn it inside out (the coated side is then on the outside). Now I simply wipe it with a damp cloth, turn it over again and can use the Smartwastebag again straight away. The coating keeps it almost clean. It is not at all disgusting to clean the emptied Smartwastebag. You can also wash the bag in the washing machine at up to 90 degrees, e.g. together with cleaning rags. To dry, hang it up to dry with the coated side facing outwards and you can use it again the next day. But please do not use hydrochloride detergent, the bag does not like that.
