1) If the water soaks in right away and leaves a darkened spot, the wood has little or no seal. Avoid water on it. Use a solution of wood cleaner, dampen a cleaning cloth and wipe the surface. You can't deep clean this wood.

2) If the drop doesn't soak in, let it sit a few minutes. If it has partially soaked in then, wood is sealed but not fully protected. Use wood cleaner, apply lightly with sponge and let sit a moment and wipe dry with cleaning cloth.

3) If the drop doesn't soak in at all even after a while, wood is well sealed. Clean thoroughly with wood cleaner to deep clean. After cleaning any type of wood, use furniture polish with carnauba wax for shine and protection.
