Oil on floor? Look up to see where it came from. If you accidentally disconnected a line from your oil reservoir while working on your windshield fluid issue, it would likely leak oil.
If your windshield is now oily and there's wiper fluid in your crankcase, you've got more serious problems.

I bought a car once that had clean motor oil in the engine coolant overflow tank. S#%t happens.
