has rust

After less than 2 years, rust has formed clearly visible at the bottom of the flap. This stainless steel should however not at all rusty, so I always thought. But Wikipedia says something else that not everyone is stainless steel. In this mailbox, it is definitely not rust.
Since the part is also still quite expensive, I have forgiven unfortunately only 1 star!

Supplement 2.7.14:

On the publisher's site at [...] states:

Quote: "If this show on the surface still traces of rust, so it is rust, which does not come from the material itself.

This on the airborne particles can be prepared by cleaning the mailbox - vigorous rubbing - easy to remove. "

Zitat2: "Long-Term Care:
For many years, the stainless steel surface is shiny when several times a year cleaning with a stainless steel cleaner, eg steel is fixed, made. "

This I will try soon and possibly. My rating high levels.
