If your dishes aren't getting as clean
as you'd like, try using only half as much
soap as you usually do.  You can also try
running hot water in the sink for a minute
or two before turning on the dishwasher,
so that the water entering the dishwasher
is already heated.  If those don't help,
there may be a problem with the
dishwasher that requires a service
technician to repair it.
