Get some sticky tape arranged so it's in a ring, but with the sticky side outwards. (I usually wrap it around my fingers) Then go over each item with the sticky, using it to pick up the bits of lint/fluff. You'll probably need to use several bits of tape to get the entire load cleaned.

I also left a tissue in a trouser pocket a few weeks ago. The entire load was really covered in bits! I let it dry, and then tried the sticky tape trick, but got bored as I was having to do insides and outsides and fronts and backs of shirts.

In the end, I just shoved the whole lot through the wash again, after I'd removed the biggest bits of lint. It seemed to work OK, but I shudder to think of what it's done to my washing machine innards!
