For Dishwashers

A dishwashing machine is one of the most labour-intensive pieces of equipment in a professional kitchen — during the day it processes hundreds of dishes and utensils, and its performance directly affects the kitchen workflow. Specialised chemicals ensure not only clean dishes but also the longevity of the machine itself — limescale deposits and food residues damage the machine’s internal components and reduce rinsing efficiency. The water is relatively hard in many areas, making the use of water softeners and anti-limescale agents particularly important.

Types of dishwashing chemicals

Detergent is the main chemical component — an alkaline-based concentrate that breaks down grease, protein and carbohydrate residues from the surface of dishes. Professional detergents are much more effective than household alternatives, as they work at high temperatures and provide the right level of foaming for machine conditions.

Rinse aid is necessary in the final rinsing stage — it reduces the surface tension of water, ensuring that water drains from the surface of dishes instead of remaining as droplets. As a result, dishes are drier, shinier and free of limescale spots. This agent is particularly important for glassware, as spots on glass are visible to customers.

Disinfectants are a mandatory component in businesses that process food products and must comply with HACCP requirements. Disinfectant washing ensures the elimination of bacteria and microbes on the surface of dishes to the safe level specified in sanitary regulations.

Chemical dosing

In professional dishwashing machines, chemicals are dosed automatically using built-in dispensers. Setting the correct dose is critical — excessive chemicals are economically inefficient and may leave residues on dishes, while insufficient dosing does not ensure the required cleaning quality.

Chemical consumption depends on water hardness, the level of dish contamination and the length of the machine cycle. Regular dispenser calibration and monitoring of chemical purchase statistics help optimise costs and ensure consistent quality.

Water softeners

Water hardness is the main source of limescale deposits in dishwashers. Built-in ion exchange softeners reduce water hardness, thereby protecting the machine’s internal components, improving washing results and reducing rinse aid consumption. Regular addition of salt to the softener is a mandatory maintenance element.

Hygiene compliance in dishwashing

Hygienically clean dishes are not only a visual standard but also a legal requirement. Dishwashing must be carried out at a temperature and with chemicals that eliminate pathogenic microorganisms. Food safety regulations set the minimum washing temperature and disinfection requirements, which must be supported by certificates for the chemicals used.

Chemicals for conveyor dishwashers

Conveyor dishwashers are used in every actively operating professional kitchen — their chemical dosing differs from front-loading models. Conveyor machines require more precise dispenser calibration, as the cycle is short — 60–120 seconds. The BHS range includes suitable chemicals for both conveyor and front-loading dishwashers across Europe.

Temperature and chemicals — combined effectiveness

The effectiveness of dishwashing depends on two factors — water temperature and chemical action. Higher temperatures (60–85°C) enhance the action of washing chemicals and provide thermal disinfection. Dishwashers with lower temperatures require additional disinfection chemicals to ensure the appropriate hygiene level.

Eco-friendly chemical choices

Modern HoReCa industry trends focus on sustainability — more environmentally friendly dishwashing agents with lower phosphate content and biodegradable compounds reduce water pollution. More and more businesses are choosing greener alternatives that meet sanitary standards while reducing environmental impact.

Inventory planning and delivery

Dishwashing chemicals are everyday consumables, and their inventory management requires attention. Consumption volume depends on the number of dishes, machine cycle frequency and water hardness. Regular ordering prevents situations where chemicals run out during peak hours.

HACCP documentation for chemical control

The HACCP system provides a record of cleaning and disinfection — which chemical was used, in what concentration, who performed the cleaning and when. This documentation is mandatory in food businesses and is checked during inspections. Professional cleaning agents with clear labelling and safety data sheets facilitate maintaining HACCP documentation.

Accessories for effective dishwashing

In addition to chemicals, effective dishwashing also requires suitable racks and water softener salt. Choosing the right racks according to dish shape and size ensures efficient water circulation during the washing cycle. A dish stacking routine prevents dish breakage and ensures effective washing with lower energy and chemical consumption.

Advantages of larger packaging

Dishwashing chemicals are available in various packaging sizes — from 5 litres for lower consumption to 20 litres and larger for high-volume kitchens. Purchasing larger quantities reduces the purchase price and delivery frequency.

Budgeting and cost optimisation for dishwashing chemicals

Dishwashing chemicals are a significant recurring expense in large restaurants or hotels — correct dosing and purchasing larger quantities can significantly reduce costs per washing cycle. Concentrated agents with lower dosing rates are often more economical than less concentrated options, despite the higher unit price. Daily chemical consumption analysis helps plan orders at the optimal time and volume.
