lip balm in the making

[lovealwaysliz.livejournal.com]

Ok, I made a post a little while ago about making some stuff for a charity craft bazarr...I ordered all kinds of goodies at thesage.com and I can't wait to get working!  However, I ordered 30 chapstick tubes knowing I had plenty of my own that I could reuse to give to my friends to sample.  My question:  How does one go about steralizing used chapstick containers?  I do not have a dishwasher, and I fear melting the little buggers in the microwave.  Is it okay to place it in a water/bleach solution?  Thanks in advance!
