Customise your detergent dose to your wash routine

Introducing our newest resource: the detergent dosage calculator.

Adjusting detergent amounts to match your soiling levels is one of the most effective ways of achieving clean laundry. Our detergent index provides suggested dosages, but these are based on a 7.5kg machine and soft water.

This makes working out your detergent dosage complicated if you have a larger machine or harder water.

To use our detergent dosage calculator, select a detergent and add your machine size, water hardness and prewash frequency. The calculator will output personalised suggested prewash and main wash dosages.

A detergent dosage customised to your wash routine? That’s right! No more working out how to adjust for machine size or how much extra to add for water hardness.

Thank you to @Alison for taking the lead on this project, your help was invaluable 😀
