Packed dirt in narrow hardwood seams

What’s a safe way to deal with dirt in narrow hardwood floorboard gaps? Loose dust seems like a routine cleaning issue, but compacted grit makes me hesitate: scraping it out could mark the finish, while brushing or vacuuming might leave it packed in place.

Would the right approach depend on whether the floor is solid or engineered, and whether it has a surface finish or penetrating oil? I’m also curious which tools and cleaners are appropriate for each finish, and when a gap is worth having assessed rather than just cleaned.

A changing gap is different from a stable seam with packed grit. If the opening is widening or a board edge moves underfoot, have it assessed rather than probing it; cleaning won’t address the movement, and probing could damage the edge. A steady seam with dirt in it, by itself, doesn’t tell you there’s a flooring problem.
