Flip the board back over and take note of the pads where the resistors are soldered in. To desolder, place the desoldering braid in between the pad and the iron. Hold the iron to the braid, clamping it against the board. The braid will soak up the solder like a sponge. Don't worry about removing solder from other pads, you can always add more later.

As the braid becomes "soaked" with solder, cut it off with wire cutters or something similar.
