Rob I'll tell you I have given though to altering things. I always feel that as the snakes contact the upper surface it needs to be cleaned just the same as the bottom doesn't it?

It is not as if they cannot reach the upper side. I know mine get dusty, They never get really dirty I don't let it. I am starting to feel like I am alone in the cleaning that upper surface of the rack I do it monthly and it is the only snake related task I don't look forward to. I don't mind hard work and enjoy the satisfaction of having something really clean afterwards but the up and down and scrubbing in a confined space is the killer.
