Query: Great except for rust on metal wheel parts

I purchased this cart in the last year and its fine in every way except today I noticed the metal parts of all four wheels are now completely covered in rust. Let me assure you the cart was not left in a wet location (a nearby but different cart is fine). Perhaps I just got a bad lot with the wrong parts, or maybe your having the same issue if you purchased the cart?
