If your doll’s surface gets stained during use, follow these steps to clean it properly:

1. Use Specialized Cleaning Oil Choose a cleaning oil that is specifically designed for silicone or TPE material. Avoid using alcohol, gasoline, or any harsh solvents, as they may damage the material.
2. Gentle Wiping Pour a small amount of cleaning oil onto a soft sponge or cloth, then gently wipe the stained area.
3. Important Notes

   1. Apply only to the stained area, avoid spreading over a large surface.
   2. After cleaning, use a clean towel to gently absorb any excess oil.
   3. Test on a small, inconspicuous spot first to ensure no discoloration.
   4. Let the doll air dry naturally in a cool, ventilated place after cleaning.

Before installing the removable vagina, please follow these steps to ensure safety, hygiene, and the best user experience:

1. Cleaning

   1. Thoroughly clean the removable vagina before installation using a dedicated cleaning solution or lukewarm water. Ensure there is no dust or debris.
   2. After cleaning, let it air dry naturally or gently pat dry with a clean towel.

2. Lubrication Preparation

   1. Before installation, apply a sufficient amount of water-based lubricant to both your hands and the inside/outside of the removable vagina to ensure smooth insertion and reduce friction.
   2. Reapply lubricant during use or before removal to protect silicone or TPE material.

3. Installation

   1. Align the removable vagina with the doll’s pelvic opening and gently insert it, ensuring it fits securely and is fully seated.
   2. Avoid forcing it in or twisting excessively, as this may damage the interface or the material.

4. Removal Precautions

   1. Before removing, apply lubricant and gently pull the removable vagina out. Avoid using excessive force to prevent tearing or stretching.
   2. Regular removal and cleaning can prevent odor and bacterial buildup.

5. Storage Recommendations

   1. Keep the vagina dry after removal, store it in a clean, cool place, and avoid direct sunlight or high temperatures.
   2. Using a storage bag is recommended to prevent dust and deformation.

When repairing cracks, always use TPE-specific cleaning oil and glue. Follow these steps carefully:

1. Clean the Cracked Area

   1. Apply a small amount of TPE-specific cleaning oil directly onto the crack.
   2. Gently wipe the surrounding area with a clean cloth or tissue to remove dirt and debris.

2. Apply Glue

   1. Dip a cotton swab in a small amount of TPE-specific glue and carefully fill the crack.
   2. Gently press the sides together to ensure proper adhesion, avoiding gaps.

3. Accelerate Drying

   1. Use cool air (e.g., a fan) to help the glue dry faster.
   2. Avoid high heat or hot air, as this may damage the TPE material.

4. Surface Finishing

   1. Once the glue is completely dry, apply a small amount of TPE-specific powder over the crack.
   2. Spread evenly to restore the natural texture and appearance of the area.
