Silly boy! Take them off and stand on them in the shower - that's better! Have a good 'tread' like with grapes, and, voila! Clean shorts! Dry them by wringing out once, get yerself dry and then wrap shorts in your damp towel and wring again.
That's what I was wondering Tynan. (Haven't done anything sensible like read the care label mind!)
I can leave them in the shower room to dry - given that almost no one else uses it.
(Apart from the bloke who was in the shower this morning LOL!! When you open the door to the little shower room - you get a view onto one the bottom of the main stairs here - I dashed out of the way quick - but don't know if any one else got an eyefull!!!)
