Spot a stubborn water stain on that cherished wooden table from Grandma? Those white marks from glasses are common, even with coasters. As someone who's restored countless pieces of antique furniture, I've relied on this simple, effective toothpaste trick for years.

1. Grab plain white toothpaste (non-gel).
2. Apply a small amount directly to the stain.
3. Let it sit for a few minutes.
4. Gently rub with a clean, soft cloth.
The stain should disappear right before your eyes! If not immediately, it will fade noticeably.
Use only white toothpaste—gel or colored varieties won't work. Rub lightly and briefly to avoid damaging the wood's finish or enlarging the mark.
