for the diy guy I would suggest a plastic snow shovel with the edge grinded down just a tad to give it a bit of a sharp edge. I would not use a regular steel shovel if I were you. I would say any plastic edge tool with an edge on it would work...just test it out in an area and see if you are getting the amount of scraping you need with the right amount of pressure. You don't want to ding up the floor anymore then you have to, of course you can touch up those areas that do get dinged.
