Query: It'll mash 'em, but then it'll rust.

I bought this here masher about two months ago, and I've been eating mashed potatoes every day, so its gotten some good use. However, I've found that with such frequent use, the masher is getting a bit mis-shapen. It also started to rust after a few cycles in the washing machine, which was unexpected! Not sure if I'm doing something wrong or what, but I was pretty disappointed in this masher. I'd definitely invest in a better masher in the future!
