Deterplus

Dishwasher detergent for very hard water

Detergent with high sequestrant power. Recommended for washing dishware and glassware in very hard water. Continued use lengthens the life of the machine. Its formulation enables it to work with water of up to 65 ºHF, preventing scale deposits in both the washed items and the machine.

Deterplus is an industrial dishwasher detergent formulated specifically to operate in hard water conditions. Its high-capacity chelating agent system neutralises calcium and magnesium ions present in the water, guaranteeing optimal washing results in tunnel and hood dishwashers even in areas where water hardness reaches up to 65 ºHF, a range in which conventional detergents lose efficacy and promote the accumulation of lime deposits on dishes and machinery.

Why Deterplus makes the difference

Chelating action up to 65 ºHF — neutralises calcium and magnesium in each wash cycle in areas with especially hard water.
No lime deposits — the chelating action prevents minerals from precipitating on dishes and glassware.
Active machinery protection — reduces scale buildup in heating elements, wash arms and equipment filters.
Phosphate-free, NTA-free, chlorine-free — formulation compliant with European regulations, with no risk of corrosion from halogens.
Compatible with automatic dosing — stable concentration in each cycle dose and precise consumption control.

01 Product description

Deterplus is a high-efficiency industrial liquid dishwasher detergent developed for environments with highly mineralised water. Its concentrated formulation integrates next-generation chelating agents capable of capturing calcium and magnesium ions before they precipitate during the wash cycle, keeping the water active and the final result free from mineral stains. Designed exclusively for use in automatic washing machinery — hood dishwashers, tunnel washers and continuous washing systems — Deterplus ensures stable performance cycle after cycle even under the most demanding hardness conditions across Spain. Its phosphate-free, NTA-free, chlorine-free, dye-free and fragrance-free composition makes it a results-oriented solution, free from unnecessary additives.

02 Benefits of industrial dishwasher detergent for hard water

Deterplus offers concrete operational advantages over standard dishwasher detergent in environments with highly mineralised water:

Chelating action up to 65 ºHF — neutralises calcium and magnesium ions in areas with especially hard water, where other dishwasher liquids fail to deliver sufficient performance.
No lime deposit formation on dishes and glassware — the chelating action prevents minerals from precipitating during the wash cycle.
Active machinery protection — reduces scale accumulation in heating elements, wash arms and filters, extending equipment lifespan and reducing corrective maintenance costs.
Phosphate-free — formulation compliant with European detergent regulations.
NTA-free — chelating agents selected without nitrilotriacetic acid.
Chlorine and bleach-free — liquid dishwasher formula suitable for continuous use in machinery with no risk of halogen corrosion.
No artificial dyes or fragrance — functional composition focused on performance, without unnecessary additives.
Compatible with automatic dosing systems — guarantees stable concentration in each cycle and facilitates consumption control.

03 Applications of dishwasher detergent in professional machinery

Deterplus is formulated as a professional machine dishwasher detergent for exclusive use in mechanical washing systems. Its typical applications include:

Hospitality and catering: washing of dishes, glassware and service trays in hood and tunnel dishwashers at restaurants, bars and cafés. Water hardness is a critical factor in professional kitchens with intensive wash cycles.
Hotels: room service and restaurant operations, where visible hygiene of dishes and glassware is part of brand image. Deterplus acts as a professional dishwasher detergent focused on final results with no stains or lime deposits after each cycle.
Hospitals and healthcare facilities: mechanical washing of dishes in food service at hospital centres, where cycle consistency and absence of visible residues are protocol requirements.
Care homes and educational institutions: mass catering with high dish rotation and frequent wash cycles in areas with highly mineralised water.
Catering and central kitchens: food production environments seeking a professional liquid dishwasher soap that maintains stable performance even with variations in water hardness depending on supply source.

04 Sectors where to use Deterplus as industrial dishwasher detergent

Deterplus is the recommended choice as dishwasher detergent for mechanical use in sectors with high dish rotation and frequent hard water problems:

HoReCa: hotels, restaurants, cafés — intensive washing of dishes and glassware in hood and tunnel dishwashers, with special need for water hardness control in professional kitchens.
Healthcare and geriatric care — collective food service at hospitals and care homes requiring a dishwasher detergent with stable performance cycle after cycle.
Service companies and facility management — management of dish cleaning in corporate buildings, educational institutions and central kitchens with automatic dosing integrated into the equipment.
Food industry — production facilities where utensil and service dish hygiene is managed through industrial dishwashers with high performance in areas with very hard water.

07 Frequently asked questions about Deterplus

What is hard water and why does it affect industrial dishwashers?

Hard water contains a high concentration of dissolved minerals, primarily calcium and magnesium. Hardness is measured in French hydrotimetric degrees (ºHF) and varies by geographical location. In industrial dishwashers, these minerals precipitate during the wash cycle, generating white stains on dishes and scale deposits in the equipment's internal components. A detergent formulated for hard water, such as Deterplus, incorporates chelating agents that capture ions before they precipitate, keeping the water active and the cycle result free from mineral residues.

Up to what water hardness level is Deterplus effective?

Deterplus maintains full chelating efficacy up to 65 ºHF, a hardness level that well exceeds the threshold at which most conventional dishwasher detergents cease to deliver optimal results. Beyond this capacity, the dosage per cycle can be adjusted in the automatic dosing system to adapt to occasional variations in water mineralisation.

How is Deterplus dosed in the industrial dishwasher?

Deterplus is incorporated into the equipment via automatic dosing, connecting the container directly to the dishwasher's dosing system. The recommended dosage is 2 to 4 ml per wash cycle, although it should be adjusted according to local water hardness and equipment manufacturer specifications. Automatic dosing ensures stable concentration in each cycle and facilitates consumption control.

Does Deterplus contain phosphates or chlorine?

No. Deterplus is an industrial dishwasher detergent free from phosphates, NTA and chlorine. Its formulation complies with European detergent regulations and eliminates the risk of halogen corrosion in the equipment's internal components, making it suitable for continuous use in professional machinery.

What types of industrial dishwashers can Deterplus be used in?

Deterplus is formulated for exclusive use in automatic washing machinery: hood dishwashers, tunnel washers and continuous washing systems used in hospitality, collective catering, healthcare and industrial catering. It is not indicated for any other system outside automatic machinery.

Does Deterplus protect machinery against scale?

Yes. Deterplus's chelating action not only protects the dishes: by neutralising calcium and magnesium ions in each wash cycle, it actively reduces scale accumulation in the heating elements, wash arms and equipment filters. This extends machinery lifespan and reduces long-term corrective maintenance costs.

Do you distribute professional hygiene products?

Deterplus is part of a complete range of industrial dishwasher detergents for hard and very hard water. If you manage the supply of cleaning products for hospitality, healthcare or collective catering, consult distribution terms and access technical sheet, SDS and available formats.
