Method of use

Please follow the manufacturer's instructions for your washing machine and place Contrad LF into the appropriate chamber.

Detergent dose rate relates to the total volume of water used by the machine in one complete cycle - not just the wash cycle.

Most washing machines use 45 to 60 litres of water in a complete cycle, which will require 80 to 120 ml Contrad LF, increasing to 200ml for very heavy soiling or problem contaminants.

Washing machines with a higher water consumption will require proportionally more cleaning agent.

For fully automatic 'self-dosing' machines, insert the dip tube into the Contrad LF container, following the machine manufacturer's instructions.
