Query: Dont over clean.

I have been useing this for just about a year now with my very stinky son :) It works great. I keep a fabric sofener sheet in there to help nix the smell and when it dose get bab enought I can notice it when in his room I take it outside and let it just "air out" plus about every two months I scrub it down with bleach and there is little to no stink. I think alot of the problems People have is that overcleaning strips the protective coat on the plastic makeing it more like to obsorb the odors. The only problem I have is That when you flip the lid a little of the wonderful smell from inside "poofs" out at you but when just siting this pal dose its job well. :) 4 stars all the way.
