How to remove the chemical smell from plastic?

Click For Summary
SUMMARY

To effectively remove the chemical smell from new plastic items, it is essential to understand that the odor often originates from residual solvents like xylene used in manufacturing. Airing out the item in sunlight for several weeks is a common method to dissipate these odors. For smaller items, using a vacuum desiccator can expedite the evaporation of volatiles. Additionally, a thorough washing with a mild detergent, followed by treatments with baking soda, soapy water, and vinegar, can help eliminate residual plasticizers and isocyanates, which are known skin sensitizers.

PREREQUISITES
  • Understanding of plastic manufacturing processes and residual solvents
  • Familiarity with vacuum desiccators and their operation
  • Knowledge of safe handling practices for chemical substances like isocyanates
  • Basic cleaning techniques using mild detergents and household items
NEXT STEPS
  • Research the effects of sunlight on the degradation of plastic odors
  • Learn about the operation and applications of vacuum desiccators
  • Investigate the chemical properties and safety measures for handling isocyanates
  • Explore effective cleaning methods for various types of plastics
USEFUL FOR

This discussion is beneficial for consumers dealing with new plastic products, product safety specialists, and anyone interested in effective cleaning methods for chemical odors in plastics.

My new plastic toy has a strong chemical smell,
does anyone have any suggestions on how to remove this smell?
Thanks in advance for any suggestions

Lots of plastic items (recently on the global market) have residual solvents used in the plastic manufacturing process distinctly evident in their odors. Most of these can be distinguished as aromatics like xylene. Everything new in our house sits out in the open air with lots of sunshine to allow it to get a good airing out. Sometimes it takes weeks.

If the object is small enough to put in a vacuum chamber (vac desicator) and pumped down, it could evaporate sooner.

After getting most of the volatiles removed, a surface washing with a mild detergent can get some additionally adsorbed material and any polar solvents that are less volatile. Some of these are residual plasticizers, and monomers or crosslinking agents. If the item is from polyurethane, the residuals can be isocyanates that will hydrolyze under the conditions of washing alternately with baking soda, soapy water, then vinegar, followed by water. Isocyanates are known to be skin sensitizers to some people.
 
I use white vinger to sink it for 3 days, which does not seem work, but parts of it sits out in the open air with lots of sunshine, which seem work.
Thanks you very much for suggestions
