The product is described as a powder, which typically implies a finer texture compared to coarse or gross salt. However, dishwasher salt is generally coarse-grained to prevent clogging the softener unit, so it might seem contradictory. Given the description as a powder, it could be a finely ground version, but it's essential to note that typical dishwasher salt is coarse to avoid clogging issues.

If you're concerned about the texture, it might be best to consult the manufacturer's documentation or contact their customer service for clarification.
