When the retics leave me some odors, I have learned from other keepers to put Listerine in a spray bottle (keep that in the room anyway incase of bites) and use it as a cleaning solution after I f10 the enclosure. The added mist of Listerine to clean has completely eliminated the smells I have encountered.

Anytime I've had a left over food for more than a few hours, a quick open window though has done the trick FWIW
