The amount of liquid detergent you should use per kilogram of laundry can vary depending on factors such as the detergent's concentration, the level of dirtiness of the clothes, water hardness, and the specific instructions provided by the detergent manufacturer. However, as a general guideline, you can use the following recommendations:
Lightly soiled clothes: For lightly soiled clothes, you can use approximately 30-40 milliliters (ml) of liquid detergent per kilogram of laundry.
Moderately soiled clothes: For moderately soiled clothes, you can increase the amount to around 40-60 ml of liquid detergent per kilogram.
Heavily soiled clothes: If the clothes are heavily soiled, you may need to use up to 60-80 ml of liquid detergent per kilogram.
It's important to remember that these are approximate guidelines, and you should always refer to the instructions provided by the detergent manufacturer for the most accurate dosing recommendations. Additionally, if you are using a washing machine, you should follow the machine's instructions regarding detergent usage as different machines may have different requirements.
