Heat marks on tables
Hot plates frequently disfigure tables by leaving on them a cloudy, white stain. This could be avoided if a mat were always placed between the hot plate and the table. The same with hot water jugs, etc. To remove the heat stains rub on a few drops of sweet oil, and afterwards polish with spirits of wine and a soft cloth.
Or hold a hot iron a few inches above the spot until the wood regains color. Polish with a cloth wrung out in kerosene.
If the spot be small, surround it with a muffin-ring, and let the hot iron rest on it a moment. It will confine the heat and rest the hand.
