The chemical contained in it is ammonium hydroxide, which can dissolve the soap components hanging on wool and shrink the sweater. Dilute ammonia water into warm water, put the sweater in, soak it for about 10 minute, gently stretch the deformed part outward with both hands at the same time, and then wash it normally. It contains chemical components that will damage wool, so pay attention to dilution and soaking time.
