The joints and limbs of your sex doll require regular care to ensure smooth movement and prevent damage. Start by inspecting the joints for any signs of stiffness, looseness, or wear. Use a small amount of silicone-based lubricant or a suitable joint lubricant to keep the movement fluid; avoid petroleum-based products that can damage materials. Gently move the limbs through their range of motion to distribute the lubricant evenly and identify any resistance or stiffness. If you notice squeaking or difficulty moving, reapply lubricant as needed. Be cautious not to force joints beyond their natural range, as this can cause tears or dislocation. For joint hinges or connection points, check for loose screws or fittings and tighten if necessary, following manufacturer recommendations. When storing the doll, position limbs in relaxed poses to reduce strain on joints. Regularly cleaning the joint areas with a damp cloth and mild soap prevents dirt buildup, which can hinder movement. Proper maintenance of joints and limbs not only extends their lifespan but also ensures a natural, realistic experience during use.
