All objects end up being subject to signs of time. Plastic is no exception to this rule. The more time that passes, the more plastic objects have a tendency of changing colours, especially objects that are white. They change from white to yellow. Thankfully, you can reverse this process with the help of a few clever remedies. You can get rid of yellow stains on your plastic objects without too much work. Here are a few technics to achieve this.

10. Try a cleaning formula

Here is what you need to create this at-home product

Ingredients:

  • A solution of hydrogen peroxide. The higher the concentration, the quicker the reaction: 12% is good but at 6% the product reacts slower.
  • About 1,5 millimeters of remover by the liter. The concentration can vary depending on the product you use.
  • A sufficient amount of UV light source.
  • A thickener (like cornstarch).

We suggest you take certain precautions while using this mixture: Hydrogen peroxide can be harmful to your skin and can damage your eyesight if it gets in contact with your eyes. Wearing security glasses and appropriate clothes are necessary to protect your skin.

Preparation:

  • On low heat, mix gradually 1 tablespoon of cornstarch with 1 glass of water in a saucepan. Stir the mixture and when it becomes homogeneous don’t add any more water.
  • When you obtain a gelatinous substance, take the saucepan off the heat.
  • Pour your mixture into a glass salad bowl.
  • Add 1 to 2 glasses of oxygenated water.
  • Mix the solution.
  • Add 1/3 of a Vanish tablet.
  • Your mixture should look like wallpaper glue. Leave it to rest for 10 minutes.

How to use this mix:

  • Spread the mix with a brush.
  • Put your objects in a sun-filled room for a few hours (but avoid the warmest hours of the day).
  • Rinse your objects with water.

You can whiten your plastic objects by mixing baking soda with a little bit of water. The mixture will create a whitening paste. All you have to do is to benefit from its whitening properties is to scrub the plastic with a humid sponge, rinse it and dry it. Take a smooth, non-abrasive sponge so you don’t damage your object.
