Answer
For marker on wood, clean first. If it remains, sand lightly with 180, then blend with 220 and 320.
Why it happens
Ink can soak into the surface fibers and may require light sanding before finishing.
Recommended grit
Use 180 only if the mark remains, then blend with 220 and 320.
Wet or dry
Dry.
Success check
The marker is reduced and the repair blends with the surrounding surface.
What to do
- Try cleaning first and let the wood dry.
- Sand lightly with 180 if the marker remains.
- Blend the area with 220.
- Finish with 320 before stain or finish.
Avoid: Do not sand a deep hollow into one small marked area.
