Mine is discolored and it looks like it has some stuff on it inside, but I think that is the cleaner and sanitizer buildup.
After I transfer anything and go to clean out, I mix a gallon or two of cleaner and use the hose to transfer from the bucket to the sink or wherever I need to clean the rest of the stuff. Then after I use the hose to transfer all the cleaner, I use it to transfer the sanitizer. After that I empty the hose and let it dry out.
