I know...it's hard to find locally in smaller bottles. You might also check with drug stores (chlorhexidine is an ingredient in mouthwash, & I can remember someone saying they wiped their enclosures with mouthwash, but I don't think I'm ready for "minty-fresh" reptiles, lol) they might actually carry it??? Only a really big operation (like a farm or vet hospital) would need a gallon of any of these disinfectants, they dilute by so much for use.
Yeah it is in mouthwash. I was going to buy a gallon from Walmart, then I read your post. I doubt I'd go through a gallon diluted. I only have 3 snakes.
