This would be what happens when you put a box with a hot stromboli in it, directly on my kitchen table. Fortunately, this time I knew what to do about it. In the past, for water rings on this table, I tried mayo. It never worked. I had resigned myself to sanding down, and refinishing the table, once the kids were a bit older. (This belonged to my husbands great aunt - one of my favorite relatives)
This table has been waxed. A lot. Not by me - I got it this way. It actually has thick foam protectors to cover the entire surface, so that it is protected all the time.. but I never quite understood why I would want a wood table top, just to cover it in foam and vinyl?
Anyway, I saw an episode of the Revolution, and learned that on waxed finishes, mayo does't work. That you need to use heat!
A soft cloth, and an iron. Do not let the iron set, keep it moving. And this isn't instant.. it will take just a few minutes.
But it's so worth the results!
