How do I keep red wine from staining glasses?

If I throw a party, I really dread having to clean up all the glasses. How can I clean out the red wine and other liquids without having to go through and clean them as soon as the guests leave?|||Fill dirty wine glasses halfway with warm water and allow to sit overnight. Cleanup the next day will be a breeze!|||rinse them w/ water or just fill them w/ the water|||clean them with white vinegar than wash them.|||Red wine shouldn't stain glass...glass is non porous and can't absorb it.
