Why does the blanket have a smell no matter how you wash it?

Blankets are widely used in daily life and usually come into direct contact with human skin. Therefore, when buying blankets, you need to pay attention to their material and formaldehyde content level to avoid buying low-quality blankets that will cause harm to human health. Next, I will answer why the blanket has a smell no matter how it is washed. Can the formaldehyde in the blanket be washed off?
No matter how you wash the blanket, there will be a smell. First of all, you need to consider whether you have bought a low-quality blanket. For blankets that are not of good quality, there will be a pungent smell. You need to communicate with the merchant in time or replace it with other guaranteed brands. Secondly, it may be that the cleaning of the blanket is not in place, and it can be sent to a special dry cleaner for cleaning, which can effectively remove the odor. If the blanket has not been fully dried in the sun after washing, a damp smell may be present.
The formaldehyde in the blanket can be washed off. Usually, the merchants will carry out anti-corrosion treatment for the blanket, so it contains a small amount of formaldehyde. As long as the blanket is cleaned with a special washing liquid before use and dried in a dry and ventilated environment, the smell of formaldehyde can be removed. Because the blanket is a fabric that directly contacts the human skin, the formaldehyde content in it is controlled within the standard range and will not cause harm to the human body.
If there is an odor in the blanket, it can be removed by washing it with the correct method.
