Rot-proofing begins with controlling moisture and airflow. Start by selecting a storage area that is dry, clean, and free from water leaks. Use moisture barriers on floors or walls if the space tends to be damp, and install a hygrometer to monitor relative humidity. Ideal ranges vary by material, but staying between 40% and 60% RH often helps prevent mold, tackiness, and structural changes.
Containment is key. Store dolls in well-sealed, breathable bags or padded bins designed to minimize contact with dust and pests while allowing air exchange. Use anti-microbial liners in drawers and shelves if possible, and replace liners periodically to prevent buildup. Consider vacuum-sealed storage for long-term preservation, but avoid crushing or deforming the form. When possible, store each doll upright with support to prevent sagging.
Pest prevention should accompany rot-proofing. Keep the room free of food and scented products that attract insects. Seal gaps around doors and use screens or door sweeps. Regular inspections for signs of moisture or pests help catch problems early. Finally, maintain a routine: check the environment monthly, refresh cushioning, clean surfaces with appropriate products, and rotate dolls to prevent pressure points.
