Pour warm water into the washbasin, then drop a small amount of household ammonia into the sweater, and the soap components left in the yarn will melt. At the same time, gently stretch the reduced part with both hands, then rinse and dry. When it is half dry, open it by hand, straighten it and iron it until it returns to its original size. Cut it into the size and shape of the original sweater with thick cardboard (cardboard of electrical packaging box), and it is best to polish the scissors with sandpaper to avoid hooking the sweater. Put the sweater on the cardboard, fix the bottom with several clothes pegs, then steam it repeatedly in all parts of the sweater with an electric iron, and take it off after it is completely cooled.
Put the washed sweater in a steamer and steam for about 15 minutes. Take it out by hand, change it to its original size and put it on the table to dry naturally. Save money without hurting the sweater. Sweaters will shrink. You can wrap it in a clean towel, then steam it in a steamer for 10 minutes, take it out and lay it flat on the board, fix it around with a clip, and iron it with an iron to restore its original size. You can iron the sweater to a height of 1cm with a steam iron. Then use a hair dryer to dry the water quickly and let the sweater set, which can prevent the sweater from shrinking.
