What happens here

Turn on the shower and observe the water flow. All nozzles should now be spraying straight and evenly, indicating that the mineral buildup has been successfully removed from the interior. Note that while the internal clogs are gone, some external white water marks may persist, as the cleaning vinegar primarily targets internal scale and may not fully remove external stains without more aggressive scrubbing or specialized products.

Goal: Verify improved water flow and identify any remaining external stains.
