Yes its pretty easy depending on how well you clean, and the quality of the soldering iron.

For almost 5 years I bought the cheap irons from radio shack and harbor freight.  One I got a soldering station with a real high wattage iron its like I was a sadist before.  It took so long to do anything before.  The iron would get hot, use it once, let it reheat and go again, rinse, repeat.  A real Iron gets hot and stays that way.
