Hydraulic Oil on Granite Wall

Our rental lift blew a hydraulic line while cleaning windows above this granite wall. Any suggestions on removing oil residue? We did not have any of our power washing equipment on-site or chemicals. The rental company tried their hot water unit about an hour after it happened and it did nothing.

I know it sucks that it’s your window contract, but I wouldn’t touch it. You try to clean it and you own it. Let the rentals insurance handle it.


That is the plan. I was hoping to help them out with chemical suggestions but I guess that could potentially open us up as well.
