Substrate boiling alternative?

Basiclly, instead of boiling a pf tek jar in a pressure cooker to kill the bacteria, why not add a solution of higher strength hydrogen peroxide in place of water to the slurry mixture of flour and such, put dry vermiculate on top, seal it and keep it dark for a few days. Then, once the H2O2 has killed all the bacteria and mold inside, take the jar out, poke a hole in the top, and expose it to bright florescent light? The light would turn the h2o2 into water, would it not? You'd then have a clean jar ready for impregnation without having to go buy and use a pressure cooker.
I'm more interested in posts dealing with the viability of this idea rather than ones that would go along the lines of, "hey man y not just git a presher cooker lol? their only like 40 bucks". Thank you.

jk, seems like an interesting idea. but i dont think h202 kills all types of bacteria, i think the heat is used to kill some of the more resilient types of bacteria, i could be drastically wrong though

sounds liek a great idea. Make up a couple dozen jars using h2o2 and then write a tech about it and tell everyone how great it is and then get a job as a moderator here and deal with a the questions why it failed.

If you mix the peroxide strong enough to kill the mold and bacteria, it will also kill your mushroom spores. Steam sterilize or PC, whether you wanted to hear it or not. Other new growers reading this thread needed to hear it. RR

This might be of interest to ya. http://www.thenook.org/archives/tek/Volume1.html It's an interesting read.
I do think that plain old steam sterilizing is easier and more likely to work for a noob.
p.s. Personally I'd only use peroxide for cobweb, as I have a PC and find pasteurizing pretty easy.
