It'll only get worse: what stains can't be washed out in warm water
There are a number of stains on clothing that are best removed with cold water.
Warm or hot water can cause unpleasant results, making the stain even more difficult to remove.
The problem is in the denaturation (coagulation) of the protein. Under the influence of warm water (from 40 degrees) it stops dissolving in the liquid. Therefore it becomes more difficult to remove the stain.
There are a number of similar stains. For example, it is not recommended to wash off blood stains, dairy products, jam, tea, coffee, fruit, and soot with warm water.
It is better to wash items with these types of stains in a machine at a temperature of no more than 30 degrees.
Delicate fabrics also require special attention. Hot water can cause shrinkage or deformation, loss of color saturation, etc.
The result will not only be poorly washed stains, but the item itself will lose its attractive appearance.
Therefore, the best option would be washing at 30-40 degrees using products that work effectively in cold water.
