Using Lemon or Vinegar
To enhance the cleaning effectiveness and improve the appearance of yellowed plastic items, you can apply the method of using lemon.
First, cut the lemon in half. You can directly use one half of the lemon to scrub on the plastic surface, or if you prefer, soak a soft cloth with lemon juice and gently rub on the stained area. By doing so, you will see the yellow stains gradually fade and eventually disappear. This is thanks to the powerful bleaching properties of lemon.
For stubborn stains or long-standing yellowing, another method will bring better results:
– Mix a solution of warm water and white vinegar or lemon juice in the appropriate ratio.
– Soak the plastic item in this mixture for about an hour to soften the stains and make them easier to remove.
– Next, use a soft brush or sponge to gently scrub, helping to completely remove the stains.
Remember, after the cleaning process, rinse the plastic items with water and dry them to preserve them better.
Using Ammonia Solution
Ammonia is a powerful cleaning agent that can quickly remove dirt and residue on the plastic surface effectively.
To use, dilute ammonia with water in a ratio of 1 part ammonia to 3 parts water. Use a soft cloth, dampen it in this mixture, and gently wipe the surface of the plastic items you want to brighten. Wait for about 1 to 2 minutes for the solution to take effect, then rinse with clean water.
Using Baking Soda
Mix baking soda with warm water to create a paste, then use a soft cloth soaked in this mixture to gently scrub the inside and outside surfaces of the plastic items you want to clean. Leave this mixture on the plastic items overnight. When you rinse it off the next day, you will find that the dirt has been effectively removed.
Using Rubbing Alcohol
A simple way to remove stains on household plastic items is to use rubbing alcohol.
Rubbing alcohol is often effective for newly formed stains. However, it may not be completely effective in removing old stains on items such as food containers or plastic dishes.
Using Lighter Fluid or Kerosene
This method should only be applied to plastic items that do not come into direct contact with food, such as window frames, motorcycle covers, and similar plastic items.
Simply dip a soft cloth in a small amount of lighter fluid or kerosene and gently rub on the area with stains, scratches, or discoloration. You will see these marks disappear, and the plastic surface will become shiny immediately.
