Fungsi Cerium Oxide untuk Kaca Mobil & Cara Menggunakannya

Cerium oxide has recently become a hot topic in automotive community forums, especially among car enthusiasts. This chemical is touted as one of the effective materials for maintaining car components. So, which components can be maintained using this chemical? And what is the correct way to use it? Let's find out the answers here!

Function of Cerium Oxide

Cerium oxide is a chemical compound derived from ceria or cerium metal. This chemical compound is characterized by its metallic gray color and catalytic properties. Given its ability to accelerate chemical reaction processes, it has become a key ingredient in automotive care products.

So, what is the actual function of cerium oxide? In the automotive world, cerium oxide primarily functions as a car glass cleaner. 

As we know, car glass plays an important role in maintaining comfort while driving. This component protects the eyes from the harsh sunlight, allowing for clear vision while driving. Therefore, this component needs to be regularly maintained to avoid dirt and scratches. 

To keep the car glass free from scratches and scuffs, you need to use cerium oxide as the best car glass cleaner. Cerium oxide can make scratched car glass smooth like new. Its catalytic and abrasive properties are very effective for cleaning stubborn dirt and severe scratches on car glass. 

In addition to being effective in maintaining car glass, cerium oxide can also stabilize engine performance. Its catalytic properties make this compound used to minimize exhaust gas emissions, particularly carbon monoxide in the exhaust of diesel engine cars. 

How to Properly Use Cerium Oxide to Remove Car Scratches

Speaking of car glass scratches, there are many causes. Starting from the friction of the wipers against the car glass, dirt and dust that have not been cleaned for a long time, to the glass being scratched by tree branches while the car is moving.

To remove car glass scratches, you can tackle it with cerium oxide. Here’s how to properly use cerium oxide on car glass.

1. Wipe the dusty part of the car glass first

The first step is to wipe the dusty car glass first. Use a soft cloth or towel to avoid worsening the scratches on the glass.

2. Spray water on the car glass

The second step is to rinse or spray water on the car glass that you want to clean. This should be done before the sanding process on the car glass. If not, the dirt still attached to the glass will increase friction between the glass and the sandpaper during the sanding process.

3. Perform the sanding process

After the glass surface is wet and clean, gently sand the scratched car glass. Next, let the car glass dry on its own. 

4. Prepare cerium oxide

While waiting for the car glass to dry, you can prepare cerium oxide. Next, mix it with water for easy application. Make sure the cerium oxide is not too watery or too thick. Use just enough water. 

5. Cover the edges of the car glass with newspaper

The next step is to cover the edges of the glass with newspaper, so this part does not get affected by the cerium oxide solution.

6. Polish the scratched part of the glass

The sixth step is to polish the scratched part of the car glass with the cerium oxide solution you prepared earlier. Polish slowly and evenly on the scratched area. When polishing the scratched glass, make sure to apply slight pressure so that the scratches can be effectively removed.

7. Wipe the car glass again with a soft cloth or towel

The final step is to clean the polished car glass using a soft cloth or towel until it is clean.

Thus, some steps you need to practice when removing scratches from car glass with cerium oxide. How about that, very easy right?
