Greetings,  I recently bought a house that has a *huge* rock in the back yard.  The previous owner had a deck built around the thing and it's really quite nice.  The rock itself is approx. 18 ft long and 5 ft. wide by 3 ft. tall.  This winter it accumulated green moss.  I tried swabbing it with a toilet bowl scrub
brush and dishwasher soap but it didn't all come off.  What's best for this?
