Somehow I've managed to get fluffy white threads all over the roof of the car:

I tried washing it with a pressure washer but the photo above is the result... still stuck on. Is there any brush/comb etc I can use to get this stuff off without damaging the fabric? The bits aren't damaging the roof (I don't think) and it's been there a while as I thought the air moving over it would whip them off. Stuck like bloomin' barnacles to a hull!
