It must be diluted correctly with water to prepare effective cleaning solutions. Product is dispensed via a standard 5lt pelican pump, manual wall mounted bottle/bucket pump or via an automatic chemical/water mixing station available from Arpal Gulf on a free-on-loan basis. 

Dish & Glass Washers

  • Switch off the electronic wall mounted dosing equipment (if applicable).
  • Depending on the capacity of the machine dilute at 1:20 parts water ratio and pour directly into the wash tank.
  • Heat water to working temperature and circulate until lime scale is dissolved. 
  • Ensure the rinse and wash jets are free of lime scale to optimise machine cleaning performance. 
  • Agitate with a scouring pad to remove stubborn heavy scale deposits.  Drain solution, refill and rinse thoroughly with clean water. 


Tea Urns/ Catering Water Boilers

  • Fill with water and add up to 10 plunges of a 5ltr pelican pump.
  • Allow approximately 1 hour for the product to dissolve the lime scale.
  • If necessary, agitate scale with green scouring pad to remove stubborn heavy scale deposits.
  • Drain and rinse thoroughly with clean water.


Floors & Hard Surfaces

If you work in a hard water area and your water supply is untreated, routine floor & hard surface cleaning may leave scale deposits that will periodically need to be removed. Add 1 plunge of 5lt pelican pump to a 750ml labelled trigger spray bottle.  Alternatively, dilute Descaler with up to 20 parts water and wash the floor or surface as you would under normal circumstances. Always rinse the floor or surface after descaling and clean again using the appropriate cleaning product.


N.B. The use of hot water will accelerate the effectiveness of Descaler.

COSHH is a law that requires all employers to take steps to control substances (chemicals) that may cause harm to employees, contractors and visitors to the workplace. Every work environment will be different in terms of the hazardous chemicals that are present, and how these are used, and individual assessments may be necessary to consider how chemicals can be handled and stored safely, in addition to ensuring that appropriate PPE and training is provided for employees. Product SDS and Product Guidance Sheets are intended to help when carrying out a COSHH assessment, however if further advice is needed with regard to specific issues in your work environment we are happy to provide advice.
