Anyone heard of - or tried - retrObrite?

[stasz]

I was doing some research on abs yellowing and came across this instructable on an open source creation called retrObrite, which will allegedly reverse the yellowing that can occur to aging abs. It's intriguing, especially since the author is Legion and the instructable uses a TK bucket.

 

Any first hand experience with this stuff?
