How to return yellowed plastic to its original appearance
Over time, white and light gray plastic parts on computer hardware and console cases turn yellow. This is an inherent quality of ABS plastic, from which the casings of almost all equipment are made. Because of this, it looks outdated and wants to be replaced. In fact, yellowness on plastic can be removed with a homemade product, and you don’t even have to rub it.
When bleaching small parts, a liquid mixture is prepared to soak them in a bath. If you need to clean a large case, then mix the composition in the form of a gel, which is spread on top. Due to its thickness, it will remain on the surface. Starch can be used as a thickener.
When preparing the cleaning mixture, it is optimal to use 8-13% peroxide. Finding it on sale is quite difficult. It’s easier to buy a 30% concentrate at a chemical store and dilute it with water in a 1:2 ratio.
To prepare the composition, you need to dissolve the stain remover in warm water. Take literally 20-30 ml of water and a quarter teaspoon of “Vanish Oxi Action” or its equivalent. This will be enough for 300 ml of the finished product.
Then stir 4 tablespoons of any starch into 100 ml of cold water.
Once mixed, it needs to be brewed until it reaches a gel consistency. The solution is placed on fire and heated with constant stirring.
After a few minutes it will become viscous even before it boils. As soon as it acquires the consistency of jelly, the heating is turned off and the mixture is poured into a separate container.
200 ml of hydrogen peroxide 30% is added to the gel with constant stirring.
Then the previously dissolved stain remover is poured in.
The finished gel is spread onto the yellowed plastic parts with a paint brush. To prevent it from drying out, the part is wrapped in film and left for a day.
After time, the gel is washed off under running water, and after drying, the bleached body is placed back in its place.
If you can buy 8-13% hydrogen peroxide to prepare the product, then water is not used. Take 300 ml of peroxide and a quarter teaspoon of stain remover at once. In order not to heat the peroxide, it is better to use cheap wallpaper glue based on starch as a thickener; it thickens in cold liquid.
Materials:
- starch;
- stain remover “Vanish Oxi Action” or an analogue with a similar composition;
- hydrogen peroxide 30%.
