cleaning seeds with h2o2 before germinating

I am thinking of cleaning some seeds in 3% h202, like a quick dunk in a cup of that...followed by a water rinse and on to germination.

has anyone done this before? will it harm the seed?

why would you want to do this?

are you just stoned?

Be careful...H202 repels moisture. It may damage the seeds, but share what happens if you try.
