Sweaters and other woolen goods can be washed separately or as a whole. The whole washing method can not only achieve the purpose of dust removal and decontamination, but also is extremely simple and easy to operate.

First, hang the sweater outdoors and beat it with a stick to remove the dust. This is repeated many times until the dust is basically removed.

Then, soak the sweater in warm water, gently knead it with both hands for a while, take it out and wring out the water, and then soak it in the washing powder solution at 40 ~ 50℃ (wash the washing powder with warm water). After soaking for half an hour, squeeze the sweater with your hands, just like kneading dough with your hands. Be sure to avoid twisting, and don't rub it with a washboard. Rinse with warm water several times after washing. You can put some vinegar in the water for the first time to make the sweater fluffy and bright. Rinse until the water is clear. Unclean rinsing will affect the bulkiness of sweaters.

The washed sweater should be put in the net bag to remove water as much as possible, and it should not be wrung out, and it should not be hung on the sweater rack directly with water, so as to avoid the deformation of the sweater and reduce the elasticity of the wool. Sweaters should be hung in a ventilated and dry place and turned constantly. When the sweater is 80% dry, you can take it out of your pocket to dry.

Finally, talk about the maintenance of sweaters. In order to prevent insects from eating, sweaters must be washed and dried thoroughly before collection. Ink can prevent insects from eating, and the collected sweaters can be wrapped in new newspapers. At the same time, the wardrobe (box) should be kept dry and put some camphor.
