This is a 10kg bag of tablet-form regeneration salt from Salt of the Earth, intended for use in the built-in water softeners found in commercial dishwashers and glasswashers. The softener unit draws on this salt to exchange calcium and magnesium ions from the incoming water supply, reducing its hardness before it enters the wash chamber. Without regular replenishment, the softener stops working and hard water passes directly through the machine.

In areas with moderate to high water hardness — which covers a significant portion of England — limescale accumulates on heating elements, spray arms, pumps, and internal pipework. Left unchecked, this reduces wash performance, increases energy consumption as scale-coated elements work harder to heat water, and shortens equipment life. Keeping the salt reservoir topped up is one of the most straightforward and cost-effective pieces of routine maintenance an operator can carry out.

Tablet-form salt is the preferred format for most commercial applications. Compared to granular salt, tablets are easier to handle, produce less mess when filling the reservoir, and dissolve at a more controlled rate, which reduces the risk of undissolved salt accumulating at the base of the softener chamber.

  • Tablet format dissolves evenly, reducing residue in the softener chamber
  • Compact tablets are easier to handle and less likely to spill during filling
  • Suitable for the built-in softeners in most commercial dishwashers and glasswashers
  • Helps protect heating elements, pumps, and spray arms from limescale build-up
  • Regular use supports consistent wash and rinse results over time

The frequency of refilling will depend on your local water hardness, the machine's salt consumption setting, and how many cycles you run each day. Most machines have an indicator light for low salt, but it is worth building a salt check into your daily opening routine regardless. A 10kg bag is a practical stock quantity for most busy sites, though higher-volume operations may want to keep two or three bags in reserve.

If you are unsure which salt format your machine recommends, or whether your site would benefit from an inline water softener upstream of your warewashing equipment, our team is happy to advise.

Frequently asked questions

How often should I be refilling the salt in my commercial dishwasher or glasswasher?

This depends on your local water hardness, the machine's salt dosing setting, and daily cycle volume. Most machines will indicate when salt is low, but in hard water areas a busy site might need to top up every few days. Building a quick salt level check into your daily opening routine is a reliable way to avoid running out mid-service.

Can I use tablet salt in any commercial dishwasher or glasswasher?

Tablet salt is compatible with the built-in regeneration softeners found in the vast majority of commercial dishwashers and glasswashers. A small number of older or entry-level machines specify granular salt only, so it is worth checking your machine's manual if you are unsure. If you cannot locate the guidance, our team can advise based on your machine model.

Should I also be using a separate inline water softener if my site is in a hard water area?

The built-in softener in your machine handles water entering the wash and rinse cycles, but an upstream inline softener can offer additional protection, particularly for the boiler and feed components. For high-volume operations in very hard water areas, an inline unit is worth considering alongside regular salt use. We can help you assess whether your current setup is adequate for your usage levels.
