in the bath as suggested - I bought 5l of ecover delicate, and used some for a down duvet ... left in the bath overnight and massaged regularly to allow suds to get inside of top
then spun gently after rinse in bath ...
layed on top of a whirly line then regularly massaged to declump it as it dried (in summer heat)
