What’s the maximum amount of laundry I can put in the drum of my washing machine?

The important thing is not to exceed half of the washing machine’s capacity (e.g. for a 5 kg machine, only dye 1.5 to 2 kg of laundry), because dyeing more than this can cause staining or mottling.

However, it should be noted that in the case of dyeing large volumes, even if we follow the same operating procedure and the same number of cases per machine, we often obtain a difference in colour between the different baths, beyond our control.
