Advice on Uba Tuba

I'm considering Uba Tuba for my kitchen countertops.  Do I need to do the lemon juice test? I have chosen Uba Tuba because it is dark and I think probably less likely to stain.  Someone wrote to you and said her Uba Tuba shows every sponge mark, streak etc.  You advised her to ask her fabricator how to care for it.  Are there general care requirements for Uba Tuba?  Is it common for Uba Tuba to streak easily?    What kind of stone is it?  From what I've read it shouldn't be sealed.  Is that true?  How likely is Uba Tuba to stain from oil?  How to you rate it among other types of "granite"?
