The XROM dishwasher pro cleaner is an all-natural tablet that uses hydrogen peroxide to dissolve the hard water minerals in your dishwasher’s tank. Using this product with a mild detergent will produce the best results, but you can also use it by itself. It is currently available on Amazon for around $20 for 40 tablets.
Best for Limescale: Finish Dual Action Dishwasher Cleaner
The Finish dishwasher cleaner contains both citric acid and sodium carbonate, making it an effective way of getting rid of the calcium deposits that cause limescale (and hard water) on your dishes. The tablets are also formulated to prevent new build-up, keeping your dishwasher fresh on a weekly basis. You can get them for around $12 on Amazon for 80 tablets.
