If you see brownish-red deposits (iron from old pipes) or if the spray arm looks like a fossil, it’s time for a descaling product like Lemi Shine or Affresh. These are designed for extreme cases. Think of them as the dishwasher’s rehab program—intensive, but effective.
And if you’ve tried everything yet the deposits still linger? Your water softener might need salt. Check it; it’s the equivalent of changing your car’s oil. Boring, but critical.
