For those times when something more than just a wipe with a microfiber
cloth is needed, there are lens cleaning fluids.  I have found two really
good ones, and a lot of rotten ones.  The cheap ones are usually just
isopropyl alcohol with maybe a little detergent added.  The good ones are
sold by Singh-Ray and Deutsche Optik.  Both of these are used by the
military and by NASA for cleaning optics.
