Cheapest place to get chlorhexidine. It's a whole gallon, and shipping is maybe $7-$8. Ships very fast too. You only have to use 2-3oz chlorhexidine per gallon of water(or more if you are disinfecting heavy duty things) and that gallon lasts a long time.

Bleach is fine, just rinse and let it air dry for a bit. It's pretty safe
