1. Sweaters made of soft materials should avoid washing machine cleaning as much as possible, and can be hand-washed with neutral or slightly acidic detergent.
2. If accidentally stained with water-soluble dirt, you can wash it directly with water; if stained with non-water-soluble dirt, you need to use stain remover oil and other volatile cleaning agents for partial cleaning first, then wash by hand. Before washing, soak in the cleaning solution for about 10-15 minutes, soaking time should not exceed 30 minutes, and water temperature should not exceed 30 degrees. After washing, squeeze out part of the water with your hands (do not over wring, so as to avoid deformation), then lay flat to dry.
