hey guys, i was wondering how to clean my bearded dragons drift wood that he has in his cage to make sure its as clean and safe for her as can be!? I got it from the pet store and just been pouring boiling water over it with a bit of bleach will this kill everything and not harm her? and should i change the drift wood often or at all? She loves her wood logs but im worried they might have unwanted bugs I clean it once a week.
