Even if you purchase a high-quality,life size sex doll, its lifespan will be drastically shortened if it is not maintained according to proper care procedures. Silicone materials can be rinsed with warm water (below 40°C) for 30 seconds—or even boiled in water for 5 minutes for sterilization—but they must be kept strictly away from oil-based lubricants, which can cause swelling and deformation. TPE, on the other hand, is far more delicate; it should only be gently wiped down with plain water or a specialized cleaning spray.
