Diffuse Coffee and Condensation Rings
You may notice the white residue left behind when you place a hot or cold dish on wooden surfaces. This is condensation, and it can be quite tricky to clean as well. However, with the help of salt, it is very possible.
First, sprinkle some salt along with the condensation marks and leave it for a couple of minutes to let the salt soak up the moisture. Then, dip a rap or sponge in some light cooking oil and gently massage the marks away, drying it with a fresh cloth afterward. This gentle method of cleaning will not harm your wooden furniture.
