My Baltic Brown is turning Grey!

My Baltic Brown is turning Grey! Description

Yesterday I sealed Baltic Brown Counter (http://GialloFiorito.com) tops upon the advisment of a sales clerk - UGH!  How I wished I had known of your website sooner!  I need serious help.  We have just moved into a new house with these Counter (http://GialloFiorito.com) tops and (http://maplered.com) after the sealing fiasco, they are now greasy, streaky and (http://maplered.com) have a thin film I cannot wipe off.  I'm assuming I will need to strip the Granite (http://tanbrown.org) , but will that be sufficient or is there another step to preserving them?  What cleaners will best preserve them in the years to come?  I thank you in advance for your response...  Marguerite
