Sink has been in for about 3 days. I was a bit nervous at first because it seemed to scratch easily but they come off. I was washing the white metal racks from my freezer and it was leaving little white scratches all through the sink cause I bought the black one. I was thinking this sink is gonna look like heck in a week cause I'm not gentle on my kitchen sink. I mean who is? All is good though. I've seen people complaining about the white residue left behind. There is one after you use it a few times. I think mine was caused from pine sol when I had the sink filled while I was washing the freezer racks. Seriously , all you need to do is easy it with a soapy dawn dish liquid rag. People are putting baby oil, coconut oil, Pam spray, olive oil ,veggie oil, stainless steel spray. All that's gonna do is cause a sticky build up over time. Just use a bit of elbow grease and some dawn. Comes right out. All in all. I like it. Good stuff.
