  • Aluminium tamper handle with black spots

    Hi!
    A couple of days ago I bought a new tamper with an aluminium handle. After only a a few days this handle got black spotty areas. Asking the manufacturer for help, he replied that I had exposed the tamper to excessive heat or chemicals. However I can rule that out, I only used warm water to clean it. Did anybody had a similar experience? Could it be a problem of the coffee bean oil or climate?

    Thanks, Steffen

    Steffen,

    Natural aluminium is both soft and very reactive.... being attacked by many things. Thats why we (Pullman Tampers) do not use raw aluminium but more expensive stainless steel or anodised aluminium.

    I would have thought the aluminium would have been anodised to offer protection against corrosion...  but that looks like a natural aluminium finish....

    I would say something has been left on the surface (I very much doubt bean oils... but something like coffee machine cleaner splashed onto it would)... and that has etched into the soft aluminium..... it doesnt take much to mark them unfortunately.

      Even water will affect raw aluminium in time, though Id be surprised it would work that quickly but perhaps there were some contaminants in the water. Either that or perhaps very poor quality aluminium (like stainless steel, there are many different grades of aluminium, some of which are much better than others). But aluminium on the whole really isnt a very suitable material in its basic form for an environment where theres heat, chemicals and physical shocks. Its mainly used because its very cheap to supply and soft to work with, which translates into faster machining time. As Robin has said the only aluminium we use in our tampers is anodized after machining, which protects the surface against this sort of thing, and hardens it to make it more suitable for the purpose.

      Unfortunately like a lot of things in life you get what you pay for, and theres often a catch with bargain priced goods. Nonetheless the rest of the tamper still looks to be in quite usable condition - just keep it clean and dry and it should last you a while.

        Hi Coffeefreak,

        Use Autosol, available at just about all auto accessory outlets.

        It will get rid of the marks and give some protection

        Another bonus.... it will shine stainless steal like nothing else, so your machine will always look like new

          Thanks for your quick replies and your help.
          Quoting Greg ... you get what you pay for ;-)

          True!!! Therefore I cant recommend the company selling tampers heavily on ebay.

            Only goes to prove that you de gets what you pays for there- or more often, far less

            With Robin of Pullman Espresso Accessories in your back yard, you could have shopped locally!

            For me, tampers are like kitchen knives: You can buy a $5 one from the local supermarket. It will go blunt rapidly and last 6 months. On the other hand, spend a couple of hundred and you have a knife for life.

            Sounds like you got duped into the $5 knife

            Given that the Chinese have ripped off the excellent Coffeelab design with a cheap rubbish imitation, its probably only a matter of time until Gregs design gets stolen as well.

            As always, caveat emptor....

              Im kinda waiting for that to happen unfortunately - there have been countless Reg Barber rip-offs out there for several years now so its probably a matter of when, not if. Nair a shortage of people willing to cash in on someone elses work. Unless youre going to shell out $50k for a patent its pretty hard to stop them too.

              Fortunately the quality of the rip-offs are never as good as the originals, not to mention the shoddy quality of the metal! : Our tampers sure arent the cheapest around (by a long shot!) but all our feedback from new buyers suggests people feel the price is more than reasonable once theyve actually handled the unit. As long as people are prepared to pay for good quality products theres not too much for the genuine manufacturers to worry about.

                How abrasive is that stuff Topshot? I recall using it on a chromed bumper on a 68 Colt years back and recall it leaving some scratches... perhaps there are different grades?
