Hi everyone, I bought 3 4'x8' expanded metal sheets but they are all rusty. I plan to use them as a floor grate for my pigeon loft so that the poop would go down through the grate and their feathers and feet will not get poopy.But the problem that I have is that the expanded metal sheets are rusty and the rust transfers orange stuff onto clothes and what ever touches it, so all my pigeons will turn orange with the rust. How should I remove all the rust?Thanks via /r/DIY http://ift.tt/2gs076c
