A gallon of this lasts a long time and you don't have to worry about airing out the bleach smell because Chlorhexadine does not have a strong odor. Great stuff.
I use a Veterinary grade broad spectrum germicidal detergent and deodorant called Clinicide - One bottle lasts for a super long time as you only need 8ml per 1L of water. I am not sure of this products availability in the States though...
