Proper maintenance is essential to keep your German sex doll in excellent condition and prolong its lifespan. Start by cleaning the doll thoroughly after each use using mild soap and warm water or specialized cleaning solutions designed for silicone or TPE. Avoid harsh chemicals or abrasive tools that could damage the surface. Ensure the doll is completely dry before storing it in a cool, dry place away from direct sunlight, which can cause material degradation over time. To prevent material degradation and maintain flexibility, apply a renewal powder or cornstarch periodically to keep the surface smooth and free from stickiness. When not in use, store the doll in a neutral position or utilize a supportive stand to avoid unnecessary stress on joints. Regularly inspect for any signs of wear or damage, and address issues promptly to prevent further deterioration. Additionally, avoid exposing the doll to extreme temperatures or sharp objects. Using a protective cover or case can help prevent dust accumulation and accidental damage. With consistent care and attention, your German sex doll can remain realistic and functional for many years.
