If you notice any rust, sand lightly with 220 grit sandpaper, use the included magnet to remove any metal chips and fragments. Delphi Customer Tip: "Heres a tip for using the magnet: never drag it directly across the glass, it will always try to wipe away the filings. Instead, place it in the corner of an envelope, for example , and drag it through. Then, simply hold it over your disposal container, pull out the magnet and the filings fall out immediately. And the white background of the envelope makes it easy to see when you finally Youve gotten them all." - Phoebe Spore, Online Product Review
