This is why your clothes aren't perfectly clean after washing in the washing machine

Contrary to popular belief, washing fewer clothes does not save water or energy. A 7kg washing machine will use as much water for one shirt as it does for a full load. Furthermore, an almost empty drum does not provide enough friction to effectively remove stains.

Golden rule:

Fill your washing machine to approximately 70-80% of its capacity.
This will maximize efficiency while protecting your clothes and your washing machine.
The effects of washing on clothes

Clothes are mostly damaged due to improper use of the washing machine. Here are some tips to extend their life:

Avoid additives. The water and detergent will not circulate properly, which may require thorough cleaning.
Also, do not overload your washing machine. A nearly empty drum reduces washing efficiency and wastes resources.
Adjust the cycle according to the type of fabric. Delicate fabrics, cottons and synthetics require special settings to avoid damage.
Maintain your washing machine for long-lasting performance.
