J'ai vu ça sur un forum (que vous connaissez surement):
----------
Natural finish woods are very easily dented or scratched. I would like to share my knowledge on how to fix such. It works 90% of the time for light dent and scratches. So, if you have made dents and scratches unintentionally on your N4, here is how to fix it.
1) Prepare hot water. Hotter the better, preferably 100C boiling water.
2) Prepare a tissue paper
3) Soak the tissue paper with boiling water
4) Apply gently to where the dent/scratches are
5) Let it sit for 3min.
6) Remove tissue paper and wipe excess moisture on the wood

Pas testé, mais ça peut être bien utile comme info si ça marche!
