TSP method of saving

[Chucker]

I've been trying to find the method for saving tomato seeds with TSP after extraction - I find references to it all over the forums, but can't find the actual method.

The link I keep finding in the threads appears to be old and gone:

Tom's TSP method: http://www.internettomatoes.net/WWA3.html

From what I've gathered from this thread http://tomatoville.com/showthread.php?t=9820 , it's a soak in 10% TSP solution for 15 minutes and a soak in 10% bleach solution for 30 minutes.

My questions are, is that all there is to the method? and, how do I get a 10% solution of TSP (not sure how to do the math with the powdered TSP)?

Thanks
