How to Remove Dents In a Walk-in Cooler
Many methods of dent removal require that you have access to both sides of the bare metal. This isn't always practical, especially with dents in large refrigeration units such as walk-in coolers; disassembling these units to access the dent can result in damage to other parts of the unit or cause seals to fail. However, you can reduce the appearance of dents in a walk-in cooler by using dry ice to contract the metal and pull out minor dings. Does this Spark an idea?

Place the wrapped dry ice block over the dent. If possible, work a corner of the ice block into the dent itself. Slowly work the dry ice in circles over the dent, allowing the metal to frost up on and around the dent. Put only very gentle pressure on the ice block, but do not press down hard.

4
Move the ice in a circular motion over and around the dent until the dent pops out and straightens. This can take up to 20 minutes.

5
Allow the metal to return to room temperature on its own. Repeat the entire procedure if necessary to remove as much of the dent as possible. Some evidence of the dent may remain, even after repeated dry-ice applications.

Tips & Warnings
Avoid holding the dry ice in one spot. Overworking the metal in this way could cause weaknesses in the metal.
Do not handle dry ice with bare hands. Dry ice can cause serious burns.
