Product review (1 stars): Magically Rusting Aluminum will stain your sink and develop holes in a few weeks
Aluminum?  Really?  Then why does it turn rust colored within a week?  Within 2-3 weeks, they have holes rusted right through.  Unlike others here, I got the correct quantity, just unacceptable quality.  I'll have them all used up in a few weeks and then I'll buy something else from someone else. Fortunately, the utility sink that my washer drains into is in my basement and it not on display because the rusting mesh leaves rust stains.
