Rit (makers of dyes) makes a laundry treatment to boost UV protection of clothes up to UPF 30. It is dermatologist recommended and has the seal of The Skin Cancer Foundation Recommendation on the box. One treatment (just add to your was, I believe) good for repeated washings. I haven't tried it, but bought the box of stuff since it sounded like a cool idea. I burn easily.
My scanner software isn't working at the moment, but if I get it worked out I'll scan the box so you can see what it looks like.
