INPUT ARTICLE: Article: Weather stripping can be purchased at any home improvement store. It looks like a long rubber tube with a groove that fits over the door panel. Lay the panel flat on a workbench and fit the strip over its bottom. You’ll need a bracket for both lower corners of the panel. Make sure the brackets are lined up evenly with the sides of the door and hang slightly over the stripping. Then, take your electric screwdriver and fasten the brackets in place with a pair of coarse-thread lag screws. Move the panel to the door and stand it upright. A tape measure can help you make sure it’s as centered as possible. Also make sure that the bottom of the door is as level with the ground as possible to achieve the perfect installation.  You can place shims on the floor to lift up an uneven side of the door. The rubber weather stripping will fill in the gaps on uneven floors as long as you keep the door panels straight during installation. You’ll need 3 hinges for every door panel besides the top one. Line up the first hinge in center of the top edge and screw it in place with a machine-thread lag screw. Place the other hinges on the panel’s top corners. You’ll need 4 rollers for the first panel and 2 for every other panel. They come on metal rods that you slide into the holes on the side hinges and brackets. The rollers should face away from the door panels. The track has an indentation for the wheels to move up and down. It’s like laying the weather stripping. Hold the track piece against the floor next to the wheels, then fit the wheels into the track. Ensure that the track is flat against the wall. Leave a small margin of space between the track and the door frame. When the track is positioned, screw the track’s brackets directly to the frame with lag screws.

SUMMARY: Lay weather stripping over the door’s bottom panel. Mount brackets over the weather stripping. Center the bottom panel in the door frame. Install hinges along the top of the door panel. Place the rollers in the hinges and brackets. Wrap the track around the wheels. Screw the track to the door frame.

INPUT ARTICLE: Article: Clean Magic Eraser. This cleaning tool can be found in most supermarkets. You may be able to find an off-brand version for cheaper as well. Make sure to scrub in straight lines from the center outwards. Apply a fair amount of force so that the eraser can polish the scratches, but not so much that it wears away the entire layer. After you've finished polishing the scratches with the magic eraser, run the disc under a water tap and dry it off with a soft cloth. When drying, use the same motion that you used to erase: straight lines from the center out to the edges. After you've finished polishing and rinsing the disc, you can try playing it again. If it still doesn't work, you can go another round with the magic eraser, or try another method from this article.

SUMMARY:
Purchase a Mr. Use the eraser to scrub the scratches. Rinse and dry the disc. Try the disc.
