granite patio table top

I and my wife recently purchased a round 44" patio table with a granite top.  It is Garden Treasures Classics product from the Java line.  The table top appears to be granite "tiles" grouted into a mosaic of concentric circles.  We have purchased a good quality PVC cover primarily to keep it free of outdoor debris.  What kind of treatment and/or maintenance does this type of table top require?

Thanks,
Petros
