Silestone Help Needed Description

We have sileStone (http://g603.net) Counter (http://GialloFiorito.com) tops in our kitchen.  About a year old, very attractive dark blue.  Recently we spilled some lighter fluid on the top while taking labels off some jars and (http://maplered.com) it left a patch which looks lighter from some angles and (http://maplered.com) darker from others (especially when wet.)  Can anybody suggest any way to get rid of this mark?  We haven't tried to clean it other than with soap and (http://maplered.com) water or windex which is all the sileStone (http://g603.net) website suggests - neither makes any difference.  Which leads me to my other question... what is the recommended care for SileStone (http://g603.net) ?  The sileStone (http://g603.net) website says very little about care (kind of implies it doesn't need any!)  Thanks.
