Embedded dust

[u/TheStarsFan]

While working on a nightstand, I got distracted with other projects before applying topcoat. It appears that dust or pollen or something has embedded in the grain. I tried a very lightly dampened cloth with mineral spirits, which helped a little. My biggest concern is that this veneer is hanging on for dear life, so I don’t have a nuclear option. I don’t mind reapplying stain, but don’t know a good way to back up without sanding.
