Textured Tile Descaler & Hard Water Preventative

The user is struggling with water scaling buildup on textured shower tiles and seeks easy cleaning tips and preventative options beyond a water softening system. Textured tiles are notoriously difficult to clean. This highlights a need for a specialized descaling product or tool (e.g., a cleaner designed to penetrate texture, possibly with a specialized brush/applicator) and a non-softener preventative solution (e.g., a hydrophobic spray or wipe-on coating) to make future cleaning easier and reduce buildup.
