Elimination of rat smell....

[mykee]

Just curious what you guys use for the elimination of that 'generic rat smell'? I keep my rat breeding racks close enough to my living quarters that even the day after cleaning, my place smells like 'rat'; not rat poop, or urine, just 'rat'. My questions to you is what methods have you guys used to eliminate or mask the smell? An Ionizer, an air purifier? Any help would be great. Thanks in advance.
