How to repair warped vinyl records

Updated November 21, 2016

Records are made of a type of vinyl that is extremely susceptible to heat and UV damage, so they often become warped under poor storage conditions. Maybe you are a serious collector who has found a rare, slightly warped record, or perhaps you have inherited a record collection with some warped disks that need to be repaired before you sell them. In either case, the situation is not hopeless; with a little care, most warped records can be repaired.

Place the warped record between two sheets of glass.

Preheat the oven to 93.3 degrees Celsius.

Place the stacked record and glass into the oven.

Watch the record. It should begin to visibly flatten after a few minutes. Don't let the record overheat; overheating can cause permanent damage.

When the record's warp appears to have been corrected, remove the record and glass from the oven using oven gloves.

Allow the record to completely cool.

Place the warped record between two sheets of glass.

Place the record and glass on a hard, flat surface in the sun.

Place something with weight, such as cans of food, on each side of the warp if the warp is severe.

Check the record every five minutes to see if it is flattening. How long it takes to flatten depends on the temperature and the severity of the warp being corrected.

When the record has flattened, bring it inside to cool. Use oven gloves.

Allow the record to completely cool.


Using the sun, instead of the oven, poses less risk of permanent damage to your records; however, it can also be less effective on serious warps, and it will take longer.
