The only way the gray tank can get sludge like that is if the valve is left open all the time. The grease and food stuffs just sit on the bottom and rot. Holding tanks need water in them for them to work properly.
Many that stay in their RV do it all the time. And many RV'ers.
Get some pinesol and pour a couple of quarts into the tank and fill with water, dump and repeat as necessary,"while you are hooked up to the sewer connction." That should clean it out and then "leave that valve closed" until full and then dump.
Which also brings up the subject does she leave the black tank open too? Cause that most likely has already created a mountain of poo waiting to clog and stink things up.
Both tanks closed and dumped when full. First Black and then gray.
