1. 1. Before washing, pat off the dust, pre-coat the original liquid or diluent of hand-washing laundry detergent on the tea stains, and let it stand for 5 minutes;
2. After that, soak the sweater in cold water 10-20 minutes (wool fabric will shrink and deform in water solution above 30 degrees, so it should be soaked in cold water for a short time);
3. Wash the soaked sweater gently with silk cotton cleaning solution or laundry detergent in water, and don't rub it hard. If machine washing is needed, choose light gear (washing temperature does not exceed 40 degrees);
4. Rinse with clear water, take it out and squeeze it dry.
note:
1, dry cleaning is recommended for sweaters;
2. Sweaters are not alkali-resistant. If it is washed with water, use a neutral detergent without enzyme, preferably a special detergent for wool. If you use a washing machine, you should use a drum washing machine and choose a soft program. If you wash it by hand, it is best to rub it gently, not with a washboard.
3. Do not use chlorine-containing bleaching solution for sweaters, but use oxygen-containing bleaching solution; Squeeze and wash, avoid wringing, squeeze out water, spread it evenly and dry it in the shade or fold it in the shade; Wet plastic surgery or semi-dry plastic surgery can remove wrinkles and avoid sun exposure; Softening agents should be used to maintain soft hand feel and antistatic properties. Dark colors generally fade easily and should be washed separately.
