① Before washing the sweater, you should first pat off the dust on the sweater, soak the sweater in cold water for 10 to 20 minutes, take it out, squeeze out the water, put it into a washing powder solution or soap flake solution and gently scrub the sweater, and then Rinse the sweater in clean water. In order to ensure the color of the wool, you can drop 2% acetic acid in the water (you can also eat vinegar) to neutralize the soap remaining in the sweater. After washing, squeeze out the moisture from the sweater, loosen it, put it into a mesh bag, and hang the sweater in a ventilated place to dry. Do not twist or expose the sweater.
② Washing the sweater (thread) with tea can not only wash away the dust on the sweater, but also prevent the wool from fading and extend its service life.

Then rinse it with clean water, squeeze out the water, and shake it loose. The wool can be directly held in a cool place to dry. To prevent deformation of the sweater, it should be put into a mesh bag and hung in a cool place to dry.
③ If the sweater is not alkali-resistant, it is better to use a neutral non-enzyme detergent for washing, and it is best to use a detergent specifically for wool. If you use a washing machine to wash, you should use a drum washing machine and choose the gentle program. If washing by hand, it is best to rub it gently and do not use a washboard to wash it. Do not use chlorine-containing bleaching liquid on sweaters, and use oxygen-containing color bleaching; use squeeze washing, avoid twisting, squeezing to remove water, spread flat in the shade or hang in half to dry in the shade; plastic shaping when wet or semi-dry can remove wrinkles, Do not expose to sunlight; use softener to maintain a soft feel and anti-static properties.
