Each of these 3 refills will produce 32 ounces of working strength chlorhexidine; just fill sprayer 75% full with distilled water, add the Chlorhexidine Solution 2% and finish filling sprayer up to circular line on the neck of the spray bottle. This is the best cleaner for your reptile’s habitat; used and recommended by exotic animal vets for cleaning your cages and other habitat items. We love this anti-bacterial, anti-fungal cleaner because it is easy to use and non-toxic to our reptiles. Basically, you spray and wipe and then if your reptile licks where you just cleaned, it won’t hurt them. Great for daily maintenance cleaning as well as monthly cleaning from top to bottom. Chlorhexidine is also helpful if your bearded dragon has some stubborn shed and you want to avoid the possibility of fungus between a double-shed area. Just pour a small amount into their bath water so that it barely turns a pale blue and let them soak. Using a soft bristle tooth brush and brushing gently against the direction of the scales will help too. See also our Carolina Custom Cages’ listing for “Chlorhexidine Solution 2%; 32 oz.
