Chlorhexidine should be available anywhere, regardless of continent. They sell it in farm stores around here.
For me, I use regular ol' Dawn dishsoap and/or Petzyme mixed with hot water in a spray bottle.
The Petzyme is good for loosening cling-ons and it does a darn good job at removing the odor by enzymatic action. It does have some surfactents in it, soapy compounds. So far 4 years later, and I used it on my snake cages, rodent cages, and it does a mean job at cleaning cat litterboxes. And I've even used it in the wash machine for deodorizing my dog's bedding. I get it in a gallon container at Petsmart.
I try to stay away from anything antibacterial in my home as well. I did a research paper on antibiotic resistant bacteria for college and it really worries me now that I know the facts. Besides, the elimination of common and harmless bacteria in the home, food, hands is one of the major causes for childhood asthma and allergies, whoda thunkit. Their body is so used to not having to fight anything, that when it does encounter something unknown it goes overboard on protecting the body and ends up going too far.
Bacteria serve a purpose, its only when they get out of balance do you have to worry. Our guts and our snakes' guts all contain beneficial bacteria, and you wouldn't be doing very well if they weren't there. Which is why after taking a long or strong antibiotic regimine, they recommend that you eat yogurt or take probiotics to build up the good buggies again.
Anyway, I never meant to lecture. But its people like my mom that don't finish out a dosage of antibiotics when sick, and then pop them when they feel ill is what I'm talking about. Or using them in poultry feed because for some reason, chickens get a growth spurt from them. Or using them in beef/pork when the animal isn't sick, just a scattergun approach (one of the reasons I try to buy organic meat). Such misuse of them puts all of us at risk for a "super bug".
Antibiotic compounds are critical in a sterile environment, such as an operating room or treating wounds. But for generalized cleaning, I think its a bit much. If good ole hot soapy water is good enough for me to eat off of, then its good enough for my snakes to slither on.
