The claim
Lay a damp cloth over the dent and press it with a hot iron. The steam swells the wood and the dent disappears.
What actually happens
This one is mostly true. A dent squashes the wood, kind of like stepping on a sponge. Heat and moisture let the wood soak up water and swell back toward its old shape. It only works when the wood is crushed. If the wood is cut or chipped, there's nothing left to swell back up. The steam also has to reach bare wood, and a hard finish like polyurethane or lacquer blocks it. That same heat and moisture can turn a finish cloudy or make it bubble.
Shallow dents in solid wood that's bare or has an oil finish. Think cutting boards, butcher block and unfinished pine.
How to do it right
- 1
Run your fingernail across the dent. If it catches on a cut edge, stop here and use wood filler.
- 2
Test the method on a hidden spot first, like the underside of the table.
- 3
Wet a cotton cloth and wring it out until it's damp.
- 4
Lay the cloth over the dent and set your iron to high.
- 5
Press the iron on the cloth for 5 to 10 seconds, then lift it and look.
- 6
Repeat with short passes, re-wetting the cloth, until the dent rises.
- 7
Let the wood dry overnight, then sand lightly and re-oil if needed.
Questions
Will this work on my polyurethane table?
Maybe, but the finish might cloud or bubble. Test it somewhere hidden first. If you're not willing to touch up the finish, leave it alone.
Can I use it on veneer or laminate?
Skip it. Heat and water can loosen the glue under veneer and make it lift. Laminate is plastic, so it won't swell at all.
How deep a dent can this fix?
Shallow ones do best. Deeper dents often come up partway, and a little filler or wax stick handles the rest.
