I didn't used a spring compressor. Just lowered the lower control arm with a jack and helped it out with a 2X4. I used grease remover on them and sprayed it off with my pressure washer. Not as good as sandblasting them but they came out pretty clean. I put POR 15 on them. Hoping to reinstall everything today, included Kirban's shield for the upper pass. side bushing. I just used Moog bushings, tie rods, center link, etc.
