In addition to the fact that some washing powders are not capable of doing anything other than refreshing the laundry during the washing process, it happens that the laundry becomes dirtier than it was before.
In this case, you should blame not the household chemicals, but the condition of the household appliances.
We will tell you how to understand what happened based on the color and nature of the stains.
Any unusual, colored or whitish spots indicate that the item in the wash is prone to fading. These could be jeans, bright fabrics, or the wash was done with high water temperature.
These are traces of rust, which often appears in the water supply system after the water supply to the house is turned off. It is also possible that metal objects could be stuck somewhere in the machine, which spoil things. These could be coins, buttons and other things that fell into the rubber seal or somewhere else during the washing process.
Sometimes household chemical manufacturers add blue granules to powders. These compounds are used for bleaching. The wrong amount of powder or the wrong temperature setting will leave blue dots or stains on your clothes.
If yellow spots appear, then in addition to the composition of the powder and its quantity, the cause may be defects in household appliances.
Basically, it is dirt accumulated in the cuff, a clogged drainage system or even a leaking seal. In the latter case, not everyone can repair the washing machine without the help of a specialist.
