Un-install & Re-install Question

[SdS49r]

How do you un-install and then do a clean re-install? I shouldn't have to ask this question - but alas! - there is the "steam" cancer taking up room on my computer. I'll save my opinion about "steam" for another thread.

Do I need to uninstall steam? or can I simply delete the Program Files (x86)/steam/steamapps/common/il-2 sturmovik cliffs of dover? What about the My Document/1C SoftClub directory?

I need to remove all of my personal settings and start fresh. There was no information on the steam site that I could find. Please help. Thanks
