When washing nothing but the Guppyfriend Washing Bag, certain kinds of washing machines may become unbalanced during the spin cycle. To prevent damage, it automatically stops spinning or reduces the speed. Therefore the laundry will not be dry enough.
To avoid that, please add natural textiles or a second Guppyfriend Washing Bag to your laundry load. It`s also helpful to just fill up the washing bag to the half and to use use liquid detergent preferably to avoid deposits in your laundry.
