Generally, when our work clothes are being cleaned, it is best to soak them in water for a while. There are still many advantages to do so. Here are the main reasons for you. Firstly, the dust and sweat attached to the surface of the clothing can be separated from the work clothes and enter the water, which can not only improve the quality of the work clothes washing, but also save the detergent. Water can be used to penetrate, so that the fabric into the washing solution before full expansion, so that dirt in the cloth eye is squeezed and floating on the surface, easy to remove. Secondly, some colored fabrics with poor wash fastness are easy to decolorize.
