Joints are the mechanical heart of a sex doll, and thoughtful care can significantly extend their life. Start with regular inspections to identify looseness, squeaks, or resistance in any hinge or pin. Lubrication is essential, but choose products compatible with the doll’s materials and avoid over-application, which can attract dust or degrade lubricants. Use a clean, soft cloth to wipe joints after use and before storage to prevent residue buildup. When posing or adjusting limbs, move slowly and avoid forcing angles beyond the design specifications; sudden, extreme positions stress connectors and can lead to cracks or tears. Supportive storage is crucial: lay dolls flat or use a purpose-built stand that distributes weight evenly and reduces strain on knee, elbow, and ankle joints. Temperature and humidity matter too—store in a dry, stable environment to prevent material fatigue and expansion that can loosen joints. Periodically tighten any fixed hardware per the manufacturer’s guidelines, being careful not to overtighten, which can strip threads. Gentle exercises, such as light range-of-motion movements, can keep lubricants distributed and joints supple. If you notice unusual creaking, misalignment, or instability, pause use and consult care instructions or a professional technician. With mindful handling and routine maintenance, joints stay flexible, reducing wear and prolonging overall durability.
