But you don't say whether you rinse the hardened paper before it dries.
That is, harden for 5 (or however many minutes) and then rinse in fresh
water before drying. I'm trying to figure out why it doesn't yellow for
everybody.... and that might possibly be the variable. And since you say
that having "run it through wet steps at least once" prevents it.... well,
it's a thought.
