Hi, I realized that the door hinges in my kitchen cabinet started to rust after 3 months. Qns: 1) is there any stainless steel door hinges? 2) did my contractor given me a lower quality hinges since kitchen tend to be moist? 3) can I just go to the hardware store and purchase these door hinges and DIY, any sizes? I hope friends online can provide me with some advice. Thank you.
