Mayonnaise takes water stains off of furniture
Cleans up nice
You can use MAYONNAISE to erase water stains from wooden furniture.**
Just spread the mayo on the stain, rub it in with a paper towel and leave it on for about 20 minutes (longer depending on how old the stain is, you may have to leave it overnight)
Wipe up the excess, then use a paper towel to rub the remaining mayo into the wood.
