Bring the torn edges of a split in the seam or spine of an LP cover together. Using the flathead screwdriver, dab glue between the two layers that need to be stuck together. Secure them with the paper clips for several hours, until the glue has dried.
Repeat the instructions in step 1 to use transparent document tape instead of glue. Bring the edges of the spine or seam together, and use the clear tape to secure them in place. Carefully trim any overlaps so that the edges of the tape are flush with the edges of the LP card.
Remove stickers by using Goo Gone fluid, a sticker remover available from crafts shops. Using a small paintbrush, dab some of the Goo Gone over the sticker and all around the edges. After two or three minutes, start gently at one edge and try to remove it gradually. Do not try to pull the sticker off in one whole piece. As you pry the edge, use the brush to apply more Goo Gone between the sticker and the LP cover. It will come off gradually.
Put the LP sleeve (not the album) in the microwave oven for 20 to 30 seconds to remove the dampness that causes mold and mildew. Afterward, spray the exterior and interior with an aerosol odor neutralizer and put it somewhere warm to dry, with the edges kept open.
