Math, a colleague of mine from Holland, told me how easily actually you can get rid of candle wax drops from your table cloth, or even your carpet.
You need to get some white napkins or kitchen towel and your iron. Turn your iron on and when it is warm enough iron the material you want to clean with napkin. When the wax gets warm, the napkin sucks all the wax. Keep on doing until the stain goes away. You will be so suprised when the stain is totally removed.
Once, I was helping a friend to clean up her place and we tried on her carpet and it worked pretty well.
Even if it is easy to remove wax drops, better not to turn the habit.
