I use those caps alot but not that method. There are methods to removing SMT caps, using 2 soldering irons, using SMT hot air station, Twist off or Wiggle off. Some swear by hot tweezers, The majority of the time I remove the bad caps with hot air.
On 68kmla/ThinkClassic we have always talked about ways to do things your self, even if you don't have the proper equipment, and Twist off is like'd by some folks, Other folks swear by the 2 soldering iron method. Sometimes with some boards... they are so F'ed up... that no matter what you do, the partially rotted pad will come off. Doesn't happen a lot to me... but it all depends on how nasty the boards is... Lately i have been getting some really nasty ones in. to each is own.
