Restoration - Un-warping a Vinyl Record

No promises, but this usually has a high percentage of success: put the warped record between two pieces of glass to form a “glass sandwich.” Apply gentle heat by placing the sandwich in the oven under low heat (no more than 150 F). Check it every 10 minutes or so. If it’s a nice, warm day you can also place it outside in the sun.

If you can find two pieces of clean, non-stick, smooth metal, try placing the record between them and ironing at a low setting.

Why bother to un-warp a record if you can still play it on the turntable?

The audio will speed up and slow down as the needle travels up the "hill" and down the other side. It only takes about an 1/8th of an inch "hill" before most people will begin to hear it.
