I have a HDS Live 12 with a "sticky" card reader. Is there a way to clean these slots? I thought about using a vacuum or maybe compressed air but I'm open to suggestions. When I push the card in it almost feels "gummy" and when it clicks, it does not spring back and does not want to read the card unless you get it just right. If you push it in too much you can only get a grip on it with a pair of pliers to remove it.
