My new(ish) fleecy-lined trackie bottoms are not only shedding bits of fluff all over the house but have also given me a washing nightmare! Since I washed them in the machine every load of washing since has been covered in bits of the stuff - driving me mad! Have tried shaking the trackies out - is there anything else I can do, if not for the trackies themselves then the washing machine? (I've checked the pump/filter and luckily it's not blocked...)
