Maintenance myths about sex dolls can lead to unnecessary costs or harm to the product. One common belief is that frequent deep cleaning is always required; in reality, routine cleaning after use with mild cleaners is often sufficient, with more intensive sanitization only as needed. Another misconception is that all lubricants ruin materials; compatibility depends on the specific coating or material—always check manufacturer guidelines before using oils or silicone-based products. People may assume stiff joints mean the doll is poorly made; often, gradual wear or storage conditions contribute to stiffness, and gentle movement combined with proper environmental controls can restore flexibility. Some think heat or sunlight is harmless; in fact, UV exposure and high temperatures can degrade materials and color over time. Debunking these myths helps users optimize care, prolonging lifespans and preserving tactile realism. The practical approach involves following material-specific instructions, maintaining a clean storage environment, and performing periodic inspections for seams, plugs, and mechanical components. By separating fact from fiction, owners can better protect their investment and enjoy a safer, longer-lasting experience.
