Extremely hard to clean.  Tight corners that may be a concern in the future, not only for cleaning but for rusting,  I had this sink and another one installed recently and the plumbing was hooked up today.  The other sink had rust develop in the corner of the basin within a few hours of hooking up the faucet.   Thousands of dollars on new granite, another 1,000 on faucet and plumbing labor and the sink is awful
Once it gets wet.    You can not ile the water stains away on this sink.
