Soup Kitchen -- Paul Ryan DID Wash Dirty Dishes

The guy who runs the Ohio soup kitchen that Paul Ryan appeared at this weekend tells TMZ ... contrary to his earlier statement, Ryan DID get dirty with dirty dishes.

Brian Antal tells us ... the V.P. hopeful was only at the kitchen for 10 to 15 minutes and only interacted with one of their "clients."

Antal -- who wasn't at the soup kitchen at the time of the Ryan visit -- said his volunteers left some dirty dishes in the kitchen for Ryan to clean.

But when we asked him if the Ryan people had orchestrated the dish-cleaning stunt, Antal said, "No comment."
