I don't know if this will be much help but I have to be careful what I wear. I've noticed that I have a lot more trouble with lint when I'm wearing my fleece sweatshirt than when I'm wearing my satin jammies.
Also, depending on the shape of the item, you can sometimes scrape the lint off the surface of the clay with something sharp and then smooth it over.
Or, you can sand and buff the piece after baking to get the lint off (again, if the shape of the piece will allow...).
Oh, and if you are using a glass work surface- I read somewhere that glass is staticky (is that a word?) and will attract lint. Marble or stone is actually a better work surface.
I'm afraid white is just a pain to work with...
