How to remove the chemical smell from plastic?

In summary, the conversation discusses strategies for removing strong chemical smells from new plastic toys. Suggestions include airing out the toy in the open air with sunlight, using a vacuum chamber to speed up evaporation, and washing the surface with mild detergent or a combination of baking soda, soapy water, vinegar, and water. It is also mentioned that white vinegar and sunlight can be effective in removing the smell.

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
 

How to Remove the Chemical Smell from Plastic?

Plastic items often emit a chemical smell, especially when they are new. This odor can be unpleasant, but there are methods to remove it. Let's explore how to effectively get rid of the chemical smell from plastic:

Q1: Why Do Plastic Items Have a Chemical Smell?

The chemical smell in plastic items is primarily due to the release of volatile organic compounds (VOCs) and residual chemicals used in the manufacturing process. These compounds can emit odors, especially when the plastic is new.

Q2: What Are Some Common Items That Have a Chemical Smell?

Various plastic items can have a chemical smell, including:

  • Plastic Containers: Food storage containers and Tupperware
  • Furniture: Plastic chairs, tables, and furnishings
  • Electronics: Plastic casings of electronic devices
  • Toys: Plastic toys and playsets
  • Appliances: Plastic components of household appliances

Q3: How Can I Remove the Chemical Smell from Plastic?

There are several methods to remove the chemical smell from plastic:

  • Air Out: Place the plastic item in a well-ventilated area, such as outdoors or near an open window. Allow it to air out for a few days to dissipate the odor naturally.
  • Baking Soda: Sprinkle baking soda over the plastic surface or inside containers and let it sit for a few hours to absorb odors. Then, wipe or rinse off the baking soda.
  • Vinegar Solution: Create a solution of equal parts water and white vinegar. Soak the plastic item in this solution for a few hours, then rinse it thoroughly and let it air dry.
  • Coffee Grounds: Fill a container with coffee grounds and place the plastic item inside. Seal the container and leave it for a day or two. Coffee grounds can help absorb odors.
  • Activated Charcoal: Place activated charcoal (available in stores) inside a container with the plastic item. Charcoal is known for its odor-absorbing properties.
  • Dish Soap and Water: Wash the plastic item with a mixture of warm water and dish soap. Rinse thoroughly and allow it to dry. This can help remove surface odors.

Q4: Are There Any Precautions to Take?

When using methods like vinegar or activated charcoal, be sure to rinse the plastic item thoroughly to remove any residue. Additionally, avoid using harsh chemicals or abrasive scrubbers that could damage the plastic surface.

Q5: How Long Does it Take to Remove the Smell?

The time it takes to remove the chemical smell from plastic can vary depending on the severity of the odor and the method used. Some methods may require a few hours, while others may take several days. It's best to be patient and allow sufficient time for the odor to dissipate completely.

In summary, the chemical smell in plastic items is caused by the release of volatile compounds during manufacturing. To remove the smell, various methods like airing out, using baking soda, vinegar, coffee grounds, or activated charcoal can be employed. Taking precautions and allowing adequate time for odor removal is essential for successful results.
