What grit removes water stains from wood?

A water stain remains on wood after cleaning.

wood wet sanding dry sanding medium grit
Answer

For a wood water stain, sand lightly with 180, blend with 220, then finish with 320 before refinishing.

Why it happens
The stain may be in the finish or upper wood fibers, so sanding must be controlled to avoid a low spot.
Recommended grit
Start with 180 only on the stained area, then blend with 220 and 320.
Wet or dry
Dry.
Success check
The stain is reduced and the repaired area blends smoothly with the surrounding wood.

What to do

  1. Confirm the surface is dry.
  2. Sand the stained area lightly with 180.
  3. Blend outward with 220.
  4. Finish with 320 before refinishing.
Avoid: Do not dig a hollow spot into the wood.
