New plastic toys often emit strong chemical odors due to residual solvents from the manufacturing process, commonly identified as aromatic compounds like xylene. To mitigate these smells, it's recommended to air out the items in a well-ventilated area with plenty of sunlight, which may take several weeks. For smaller items, using a vacuum chamber can expedite the evaporation of volatiles. Additionally, washing the surface with mild detergent can help remove any remaining adsorbed materials, including polar solvents and plasticizers. For polyurethane items, residual isocyanates, which can be skin sensitizers, may require a washing method that alternates between baking soda, soapy water, and vinegar. Immersing the item in white vinegar for a few days may also help, although results can vary.
