    Perennial cleaning question on Semi Relic helmet

    Bear with me , as this will be lengthy to address all I have read on WAF about the question I am humbly asking you all (and to show I have attempted to do my homework).

    I am soon to have in a few days an M42 double decal Polizei helmet in a semi-relic/relic helmet state, that was, it appears to have been underground at one time.
    This has pronounced rust (seems to be reddish and possibly the powdery kind) and even possibly dirt issues on inside, yet outside does not have much issues at all.
    Now, I have indeed, utilized the search function for my volitile and contentious and yet perennially monotonous question....
    which is.....
    I want to do some clean up/treatment on the inside of lid.
    My reasons are: I do not have a optimum humidity control and live in an area that half of the year has now become overly humid(70 to 90 %) humidity due to Climate change and proximity to ocean.
    I plan on keeping the helmet in a semi air-tight glass shelved cabinet and dont want rust and dirt falling out on shelves ,nor causing any possible issues with any other items that may end up displayed in same cabinet.
    In side this cabinet I keep, monitor and maintain multiple containers of dehumidifying agents.

    In my searches here on WAF Conservation and the helmet forums I have read much intelligent arguments as to doing nothing to non relic helmets and as to doing nothing to fully relic condition relic helmets.
    This helmet I am getting is in a grey area of being inbetween both camps...plus the outside of helmet has obviously been cleaned /treated to some degree already prior to my getting it.
    So...any advice is welcome

        one more

        one more from other side.

        to reiterate, I am not hoping to restore anything, just do a bit of cleanup inside lid...and if there was somthing to make that inside rust rendered inert, would be nice.

          Hi Michael. As a conservator I do not support helmet restoration. However I do believe that's a personal choice.
          I remember this link http://dev.wehrmacht-awards.com/foru...et+restoration. He seems to have done a very nice job. You may want to contact this person for ideas and help. Good Luck. Paul

            Ouch!
            Hello Paul,
            Thanks for your reply and I have great respect for your threads that I have perused in the past, but perhaps I am having problems with clarification of terms.
            I dont wish to "restore" this helmet...nay, far far from it. But I do not consider leaving the inside of the helmet with dirt and an active looking rust to be my only other option.
            Would you consider my idea of removing some dirt and rust from iside as renovation?
            Would a museum really leave the inside of such a helmet as mine is without removing the dirt,etc?
            respectfully,
            thanks
            Michael

              Hi Michael, Thank You. I would say that it depends upon the policy of the museum, and the conservation department (if the museum has a conservation dept). Most conservation department with a chief conservator would leave the helmet interior a lone (or use the below described minimal restoration). Years ago some museums did treat rusted metal by using a fine silica sand blasting method and submerge the metal in an epoxy.<O</O
              <O</O
              Years of this treatment on metals continued for years. Some studies found some metals continued to rust and treatment chemicals are merely a temporary stop gap method. However newer epoxy resins have emerged over that past 20 years achieving a much better end result. Water conservators have had some great success with both water logged wood and metal. This process of conservation is expensive, and is still somewhat a new venue using newer sealants epoxies. Again these treatments are fairly new without a history of time to monitor their effects on artifacts. <O</O
              <O</O
              For now I would take a clean cloth and wipe out as much rust and debris as possible. Using fine 0000 brass wool to pass over the rusted interior. Following with another clean cloth wipe down of the interior. Also keep the humidity levels fairly in close range. I hope this helps. Paul

                IMO using brass wool spoils the look of relic helmets.
                You can start by washing it with water and a toothbrush, and be carefull of the decal areas so as not to risk damaging them.

                  I would use brass wool interior only. Paul

                    Hello Jean-Loup,
                    then dry it out in an oven or via a hot sunny day?
                    Have you ever found water damage from cleaning this way?
                    thanks,
                    Michael

                      thanks PaulR

                      PaulR,
                      I see--- so even museums may only use brass wool on inside or a hard to get new tech epoxy with no track record.
                      Very interesting and a bit amazing(in a sad way) as I always assumed with enough money to throw at a problem, some museum's scientific conservator researches would have figured out their needed "magic bullets" on things like rust for their metal objects.
                      but assuming things can be a mistake

                      thanks for your input, as it is not to be frivolously ignored.
                      -Michael

                        Michael,
                        Thanks. Unfortunially the days of large muesum funding are gone. Like most of us, or the places we work. Most museums are under a very tight budgets. Only very sever items gets first attention.
                        Just remember any hard sanding, or sand blasting will remove metal as well as rust. Rust is kind of like pot holes lots of deep impressions to clean. Paul

                          Hi Michael, i want you to read one of my threads on cleaning a semi relic helmet, about the same condition as yours. Scroll down a bit in the thread

                            Wow, some strange ideas to my eyes. Wash a rusted helmet with water and a toothbrush? Bead blasting and epoxy? Maybe I am from another planet, but I have always put a good grade oil on rusted metal with excellent results. I would leave the outside of the helmet alone and wipe the inside with a rag covered in oil.
                            best wishes,
                            jeff

                              As a conservator
                              1. I don't support washing any helmet in water. I was merely talking about drastic measures some museums and people take to stop rust.
                              2. I do not support sand blasting or sanding peroid.
                              3. I don't support oil is not a good idea. Oiled objects gathers moisture, grim, and dust let alone drips of oil for a long time.
