Several have mentioned that once cleaned, certain products seem to delay, or prevent, the problem from returning. For years, I have used Wenol (http://www.wenol-polish.com/) on stainless and titanium exhaust, with great success. It very much seems to delay the staining, and weird discoloration, seen when these metals get hot. Doesn't have to be just exhaust, as it is an incredible polish on all metals. Came across it at a car show, about 20 years ago, and have used nothing else since. Have not tried it on the CB yet, but expect nothing but stellar results. Unlike some of the other products folks have mentioned, there is no danger associated with getting it on surfaces that you didn't intent to.
