What kind of clothing cannot be dry cleaned: rubber products (including elastic bands), accessories with metal, artificial leather, painted decorations (such as lacquered flowers), polypropylene clothing (including waterproof silk, etc.), and velvet products bonded with glue.
b. Will frequent dry cleaning shorten the lifespan of clothing? No, on the contrary, frequent dry cleaning can extend the life of clothing. This is because, when washing with water, the fibers of the clothing swell first, allowing detergent to penetrate into the fibers during washing, making it difficult to clean thoroughly.
