Warm, soapy water is the answer (as it has been for decades ) - it is also the cheapest by far. Apply using a soft, clean, cloth; or kitchen-style sponges that are cheap enough to be used just once or twice. Cotton buds come in handy in "nooks and crannies". Wipe off with paper tissues that are then binned.
Only use solvents and (or) aggressive detergents or disinfectants when absolutely necessary (if at all).
