Well, presumably there are ways to kill Ghouls. Remember, Quinque were only invented within the last 50 years but the Washuus were famous Ghouls hunters during the 19th Century.

The best guess is right above us, if Arima did kill a Ghoul with an umbrella....it was probably by stabbing through the eye. It's already established their Ghouls' mucus membranes aren't protected like the rest of their body.
