Denny, the hot microwave would work as well since we only need to sanitize and not steralize.
just for the record Ethanol (Vodka / Everclear) is a great sanitization media.
A quote from Wikipedia
Ethanol is used in medical wipes and in most common antibacterial hand sanitizer gels at a concentration of about 62% (percentage by volume, not weight) as an antiseptic. Ethanol kills organisms by denaturing their proteins and dissolving their lipids and is effective against most bacteria and fungi, and many viruses (including SARS ), but is ineffective against bacterial spores."
I just keep a spritzer bottle of ETOH around the house out of habit.
