This happened to me recently, but not just a small ring on the table. I had been making roman blinds and used the table to press the seams; of course I had used a thick folded cloth to protect the surface, as I have done before, but my new iron is a little more ferocious and a very keen steamer. The resulting iron prints down the length of the dining table simply couldn't be regarded as 'characterful'.

Well, I had that in the fridge so I decided to give it a go. I dabbed a test area thickly with the mayonnaise using kitchen paper and put the kettle on. After half an hour I went to check on the progress and to my utter amazement, found the less obvious marks had disappeared; I whipped out the jar and dabbed the whole table with it. The table was already well used and had various battle scars which could benefit from a little treatment.

So, no need to panic! This simple, quick and inexpensive trick really does work wonders.
