I buy the silicone spray at my sewing machine store and can also get it at the local jobber. I spray it on the bed of the machine, and all of the table surrounding, then wipe off the excess with a paper towel.
BE CAREFUL ... and overspray onto your floor, can make it VERY slippery and dangerous!
Here's a link to a quilt I did with a fleece backing. I made some notes about my experiences with the fleece that might help you.
