Removing a Heat Stain from Wood

Ever have this happen to you?:


I have it happen a lot since I use my dining room table to cool cakes or cookies. Sometimes a pan is so hot, it goes right through the pot holder it's sitting on.

I did some research and found that you need 2 things to get rid of this:

2. a cotton sheet

Apparently heat removes heat. Genius, amazing, shocking.

My table looks clean again!
