When a sweater is just bought, the size is just right, but after washing, the sweater will shrink and thus become smaller, so how to deal with the sweater shrinkage? What methods can be used to recover? After the sweater shrinks you can use a softener to recover, just add the right amount of softener to the water, then put the sweater in, soak it for an hour, start pulling the sweater by hand, and wait for the sweater to dry to restore the original look. If conditions allow and you are not in a hurry to wear it, you can send the sweater to a dry cleaner, who will usually turn it into its previous size by means of high temperature. Or use a steamer to put the sweater in a pot for more than ten minutes, take it out, then use a stretching method and finally hang it in a cool place. When cleaning the sweater, it is best to use warm water for cleaning, by soaking in warm water in washing, and finally by hand a stretching. The sweater should be cleaned by hand washing, not by washing machine at all, otherwise the sweater will not only shrink, but also lead to deformation of the sweater, affecting the appearance of the sweater. You can also wash the sweater with shampoo, because shampoo contains plasticizers and bulking agents, which can make the sweater loose and will not make it shrink. Once the sweater is washed, squeeze out the water by hand and hang the sweater to dry on a hanger. If the hanger is large, it is best to lay the sweater flat on the hanger to prevent it from being deformed. Some sweaters can be dry-cleaned, and you can send them to a dry-cleaner to be cleaned, but the price of dry-cleaning is not very cheap, and if you buy a sweater for a few dollars, you don't need to send it to a dry-cleaner to be cleaned.
