Is exposed aggregate harder to clean than plain concrete?

Somewhat, yes — its textured surface can hold onto dirt and grime slightly more than a smooth plain concrete surface, though this difference is genuinely modest with regular sweeping and periodic washing.

Proper sealing significantly reduces this difference by giving the surface a smoother, less porous top layer that resists dirt and staining far better than an unsealed exposed aggregate surface.

General maintenance — regular sweeping, occasional washing, and keeping the sealer in good condition — keeps exposed aggregate looking good without needing meaningfully more effort than any outdoor concrete surface.
