I'm giving another pass on the Duo Pad. The edges were still pretty yellow. Some elbow grease with the gel seems to have cleaned it up a bit. I put the pieces in bleach again and stuck them on the patio in the sun with some taped-up pennies to hold them down in the bleach. I'll probably leave them in longer than last time to see if it sucks the remaining yellow out. I'm trying to find out if I can get CDRs to work in it so I don't know if I'll get to the actual Duo today.. I'm trying to find an old drive that can write at 1x, since the minimum mine writes at is 8x and I'm guessing that's what the problem is.
Anyways, if I can at least the get Duo as white as the controller have already gotten I'll be pretty content with that. Now I just need to get my girlfriend back to Japan so she can get me some Super CDs.
Ninja Spirit, undiluted bleach means straight bleach with no water added to it. I made a mistake in my first post in that I did add a VERY small amount of water to make sure the entire controllers were submerged (I ran out of bleach). Again, very small amount.
