To supplement what Tom Lee has written, I can only add that I experienced "exploding caps" only on one of the two boards I did, and there were only two caps that blew up, and the reason why is because I used a tweezer-style desoldering tip that applied a lot of heat to both sides of the cap itself. Suffice it to say, you will likely NOT have an exploding cap. And even if you use tweezer style desoldering tips, so long as you don't apply too much heat, the caps won't blow up. I put extra heat on because I wanted to cleanly yank off the cap without any possibility of breaking the trace (which could happen if I didn't apply sufficient heat to melt all the solder but then "yanked" up anyway).

So really, there's not much you need to worry about. Just be sure to solder in your replacements in the correct position polarity-wise!
