Rusty brackets I do not let on my bread!

Had 2 cups ordered, one for me and one to give away. Unfortunately, both the brackets that hold the pipe elements were already rusty! One had also yet discoloration :-(
My bread I will not let it (even with towel) rise ... And to give as good for the clear either!
Too bad, because otherwise the baskets are beautifully finished and natural material is logically not always evenly. I do not understand why for the price (yes, they exist even cheaper ...) does not use at least stainless steel clamps. A second attempt with this product, I did not dare - even if at a replacement brackets were still ok, but they would start after some time to rust ...
