Query: Work great - last about a year

These work great for cleaning wine glasses, I use them to clean just about everything these days - knives, all glasses, plates, whatever, just cause it's in my sink already and convenient. I've dishwashered them with some success but rust does eventually show up on them. some Whink and it usually goes away teh first time, by the second time it's destined for the trash, but I sure do love these!
