I'm with Homer on this one. An occasional rinse in star san and a good thorough rub a dub dub will be sufficient since it is on the unsterilized side of your system. Once the wort leaves there and gets boiled cleanliness becomes a cardinal issue. Where youre at in the process is not dangerous and should not risk contaminating your brew.
What do you mean "no Kidneys"???, WTF now I gotta drink less beer...
