water mark on wood

[chivers]

How do I remove a water stain from a teak veneer sideboard?

It may sound counter-intuitive, but placing a soft cotton tea-towel over the mark and applying an iron on dry setting should remove the mark. If you don't fancy that, an equal mixture of white toothpaste and bicarbonate of soda rubbed over the spot can work. Finish off with a light rub with olive oil.
