1. What Happens to Plush Toys Inside a Washing Machine and Dryer?
Inside a washing machine drum, plush toys are spun together with water. The dryer requires special attention. Sites from Japanese washing machine manufacturers explain that dryer temperatures in coin laundries can reach about 50 to 70 degrees Celsius (122 to 158 degrees Fahrenheit), which may cause parts to melt [1]. The centrifugal force from the drum’s rotation might also distort the toy’s shape. For toys with eyes or noses attached by glue, washing may cause the glue to dissolve, leading to parts falling off or the shape changing [1]. There is also an explanation that melted glue sticking to surrounding materials can destroy the fluffy feel. However, no experimental data was found to confirm the direct cause of fur becoming rough after washing. It is only suggested that heat, tangling, and leftover glue could be contributing factors.
Does putting a toy in the washing machine guarantee safety? Not necessarily.
2. Why Does Hugging Make Plush Fur Lie Flat, Like Carpet Pile?
Fur changes even without washing. Daily hugging can make the fur lie flat. To understand this, we can look at terms used for carpet pile. Technical documents from the American Carpet and Rug Institute (CRI) divide changes in pile into two types. One is "crushing," where the pile’s thickness decreases due to stepping on it. The document states that the pile may or may not return to its original state. The other is "matting," where the twist in the yarn reverses and the tips become tangled [3]. The flattening of plush fur from hugging might be similar to crushing, while the roughness after washing might be similar to matting. However, this is an analogy borrowed from carpet definitions and has not been verified for plush toys.
3. Can Crushed Plush Fur Be Restored?
According to CRI documents, dents caused by the weight of furniture can sometimes be helped by lifting the pile with the edge of a coin and using a vacuum cleaner and steam (or hot water extraction) to aid recovery. However, the document explicitly states that some dents are permanent [3]. This shows that whether flattened fur returns depends on its condition. Immediate care may help, but sometimes it does not return. This is information about carpets and does not mean the same methods should be tried on plush toys.
4. What Do Plush Toy Makers Like Steiff Recommend for Washing?
Steiff, a long-established German plush toy manufacturer, provides guidance on its official website. Many plush toys can be washed in a washing machine at 30 degrees Celsius (86 degrees Fahrenheit) or below, alone, and inside a laundry net or pillowcase. Drying should avoid high heat; they should be dried at room temperature. It is suggested to shake them or gently comb the fur during drying. The website warns against using radiators or dryers [2]. On the other hand, collector items made of mohair or alpaca are not suitable for washing machines. For these, the surface should be gently rubbed with foam from a neutral detergent and rinsed carefully with a small amount of clean water. Combing the fur while drying is recommended [2]. The manufacturer’s advice to avoid washing machine heat aligns with the warning about heat and centrifugal force mentioned in the first section.
5. Why Do Museums Choose Not to Wash Old Cloth?
The Museums Galleries Scotland association states that museum textiles should not be washed. If treatment is needed, one should consult a conservation specialist. The document notes that wool, silk, fur, and feathers can become food sources for insect larvae, and exhibition light should be kept to about 50 lux [5]. Regarding storage environments, the Smithsonian Museum Conservation Institute (MCI) sets guidelines for textiles at a relative humidity of 45 percent plus or minus 8 percent, and a temperature of about 21 degrees Celsius (70 degrees Fahrenheit plus or minus 4 degrees Fahrenheit). They explain that if it is too dry, natural fibers become brittle, and if humidity is high, mold and fabric-eating insects increase [4]. However, these are general guidelines for textiles, not specifically for plush toys, and are not requirements for home environments. They help us understand the idea that the act of "washing" itself can trigger damage for old items.
6. Why Were the Repair Marks on the Original Winnie the Pooh Plush Toys Kept?
Records from the American Institute for Conservation of Historic and Artistic Works (AIC) meeting discuss the conservation of the original plush toys that inspired Winnie the Pooh. Conservators added cotton cloth to the back to support missing parts, covered them with dyed alpaca plush, and maintained the structure to prevent sawdust from leaking out [6]. Interestingly, they chose what to repair. Reports state that they kept the loving repairs made by the previous owners, the Milne family, and only removed the rough repairs done by the publisher during a world tour [6]. Damage and repair marks on plush toys hold the time they have been used. In conservation, there is a judgment to keep marks made by the owner. This record does not mention washing the fur.
7. How Can You Check Whether Your Own Plush Toy Can Be Washed?
For today’s activity, look for the tag on your home plush toy to see if it can be washed and if a dryer can be used. If it is not written, it is safer not to wash it and just observe. Gently adjust the direction of the fur with your fingers and observe if flattened parts puff up slightly. Do not rub hard. For the next step, look at your favorite plush toy for repair marks or places where the fur direction has changed. The time it has been used might be preserved there.
