Everyone's method of dumping tanks and staying clean are different. I use a big pair of green gloves and after being done put them in a bag in that compartment.Before entering the coach my wife meets me at the door with hand cleaner. No matter how careful we are we still get dirty.
Each time you go to a supermarket what is on the handle of the grocery cart, door handles everything you touch in public places.
I have too many times seen someone leave a washroom after doing the number two and not washing their hands. Also people changing babies diapers and not washing their hands. And it seems to be ok to just throw said diaper in the garbage can. Then all that stuff goes to the landfill. Yup I am starting to rant! There are worse things than dump stations.
