Saving water, saving electricity, all well and good, but what does this have to do with the dosage of detergent?
Before, the laundry was washed in full water in a drum full of water: 150 liters of consumption. Now, the laundry is simply soaked with water, there is only a little water in the drum. This laundry impregnated with water and detergent, agitated by the rotations of the drum, will be washed by rubbing on itself .
If the detergent concentration is too high, the laundry becomes sticky and viscous. It no longer rubs, but slides on itself and does not wash. When it comes to rinsing, and as we know, machines save water, the laundry will be poorly rinsed. So, do not forget:
Too much detergent = poorly washed and poorly rinsed laundry
No more than one cap for a machine of 7 to 8 kg of moderately dirty laundry.
Half a capful for half a machine of lightly soiled laundry.
Let's limit packaging, limit discharges into the environment even if they are biodegradable, limit transport and our carbon footprint, reduce our expenses.
