Great idea. I have always just washed my wooden cutting board with hot, soapy water but wanted to try your method as an extra measure of food safety. I opted for the lemon juice this time around, but will try the hyrdogen peroxide next time. Made for Fall 2012 Pick A Chef.
I read that if you want to clean and sanitize the surfaces in your home, spray with hydrogen peroxide and vinegar (order doesn't matter). This is the same thing they use for contaminated meat or food (but I believe they use a higher percentage then the 3% you normally buy at the drug store). So it should work just fine for counters and such. Also don't worry about rinsing off the hydrogen peroxide, since it's h202 and breakdown to h20 and 0. (So water and oxygen). One last thing, it's the extra oxygen that actually kills them since they can't live in such a high oxygen environment and that's what causing the fuzzing.
I loved the idea of the hydrogen peroxide. I am always worried about having cleaned the cutting board well enough, especially when a sponge has sat in the sink with stuff on it as well, it may look cleaned off but i dont know that soap and water does enough.
