    Removing Bluing from Exhaust Pipes

    I've searched every where for a way to remove the bluing from my exhaust pipes. I've read that Blue Off or Blue Away or vinegar on aluminum foil and several other remedies. Does anybody have a method and or product that has really worked and removed the bluing? Thanks.

      I've used Blue Job,


      No 1 & 3 were pretty blued, check it out.



      After Blue Job, you couldn't see cyl 1 in the above photo but it was just as blue as no 3 was which you can see. This is an after photo. But..... make sure you wash it off after you use it, any residue left will turn it black or make funny designs then you'll be using Turtle Wax chrome polish to get that off (ask me how I know). It takes time if you do it the finger with rag rubbing style like I did, and use the least you can get away with.
      Below, after "Blue Job" also whatever made those pipes blue will cause it again if you don't correct it, my case, lean carb settings.

        +1 on Blue Job. Great stuff but you need to be patient and take the time to do it right. Did mine 3 years ago, and after proper carb work...they were way too lean from previous owner...haven't had to touch them.

            Something very wrong happened to that V&H on the 1100G. I've never seen pipes so blue before. Hope the engine isn't cooked now.

            Regarding Steve's 1100E, blue pipes like that are the result of excessive idling, or running without airflow over the engine. I bought an 850 with gummed up carbs and the pipes looked like that. The original owner let the bike idle in the driveway in an attempt to clean out crap in the carbs and the pipes were damaged in the process. On that bike there was nothing I could do to remove the blue. Spent at least an hour trying to polish them with only minimal improvement.

            Oh, and stay away from aluminum foil on chrome unless you don't mind scratches.

                this and a tube sock work well.
                DO not use aluminum foil it will scratch your pipes in spite of what people say.

                At last an elegant use for tube socks.

                  I think, and I say think the blue pipes resulted from some very lean carb settings, a air cleaner cover that was mesh when it should've been solid, (I thought it was stock for the longest time) and who knows what else, as I am the 4th owner. I did put a different set of carbs rebuilt by Chef on it. Those two cylinders still run hotter than the other two. The valves have been checked and found all within spec's.


                  I must tell my friend about the aluminum foil scratching, as he says it works really well on polishing the chrome on his bike, (he has a Harley).

                    I haven't seen simichrome polish in a long time, I used it exclusively in the '70's. Really good stuff.

                      solvol autosol is good for light bluing but not really heavy bluing

                        There's a local bike shop called bigtoy that I used to work at that carries simichrome. They swear by it, and yes it is good stuff.

                          Many thanks for all who replied to my question, thank you. I used Semichrome alot back in the day, but I haven't seen it on the store shelves in years. Thanks for the link to orderit on line, which I did today. I also tried Blue Job, but I guess I wasn't patient enough, I'll try it again. The PO had the bike running extremely lean. I bought it with a bad starter, so I don't know if the motor is toast or not. I hope not. It turns over by hand and seems to have compression. I have the starter apart for rebuild. I also have the carbs apart for rebuild. Funny thing, they were missing the slide springs! I didn't think a bike would run with no slide springs installed, but he claims (as all PO's do) it ran good until the started went on the blitz. I'm guess he screwed up the carbs and burnt up the starter motor trying to start it, but he denies that, of course. I love the red paint jobs, thinking of repainting mine in red. I'm not too crazy about orange. Thanks again for all the suggestions and information. This is a great forum and I'm so glad I joined it.

                            Some carbs do not use the springs. Check the parts fiche for your bike, it may not use them.

                              Thanks so much koolaid kid, but I already checked the fiche and these do use springs, at $10 each from Suzuki! I called the PO and he said he "found" the springs in his toolbox and he must have "forgotten" to install them when he cleaned the carbs. He is mailing them to me.
