Washing reusing Wyeast 1272

[lovebrewin]

I have a beer that is full of diacetyl and I'm 98% sure it was caused by my poor wort chilling methods + high pitch temp and not from infection. The yeast is wyeast American 2 1272. I'm wondering if I can wash the yeast and reuse it or would I be better off just getting a new smack pack and starting again?

Whenever I have doubts about a yeast cake, I just dump it and start over with a new smack pack. Some will probably call me an alarmist, but I figure it's cheap insurance.

I agree with krahm. While your yeast might be perfectly good if you wash it, you're risking time and ingredients for an entire batch for what amounts to an $8 vial.
