how many tubs are you cleaning that it takes 4-5 hours? Last week I did a full clean up, disinfect tubs and the rack itself, new cypress, all water bowls and hides cleaned. 8 baby bins 3 medium tubs 15 adult tubs and also 4 4ftx2ft cages all cleaned in about 2 and half hours. I also spot clean as often as I can remember to so I don't get poop smears that often. I have never had poop on top of the rack, only the side of tubs.
