Another option (albeit slow acting, pro/con) is using straight 3% hydrogen peroxide + UV like you get at the drug store. I used this method on a few of my Commodore 128D pieces that were yellowed. It does act very slow, but that might not be such a bad thing considering people have had issues with blotchiness with stronger treatments.
