I have 34 of these discolored $500's. I filtered them out from a larger group of 3 or 4 racks. Most have some discoloration or weird gunk on them. I tried cleaning them a few times in Oxy bath and/or ultrasonic, but gave up after the third try. I am not sure if they can be redeemed, but these are free if anyone wants to try or can use them as is.
Free + $8 shipping.
