Can this be used safely on a down jacket...
Can this be used safely on a down jacket with DWR treated fabric? I would like to protect the DWR but of course do not wish to damage the delicate down feathers. Thanks!
Best bet is to use Nikwax Down Wash to clean the garment and then treat with Nikwax Down Proof. It's designed to restore DWR on down garments without damaging the down.
