If you want to use robots.txt for that "clean up", this should be the right way:

Disallow: /*?

Depending on your situation, there may be more value in Jim's response about 301.

In my example, I have URLs that come from paid search where I throw variables on so I know which campaign, ad group, keyword, etc. the traffic and sale has come from. Since I already have my original page, and the rest is all same page with variables attached (duplicate content), I believe that 301 solution would fit better, rather than blocking via robots.txt.

It would be great if someone could comment more on the difference.

Thanks
