[Nighttime Car Care] Plus, having this is convenient! What happened to the headlights and the dashboard?
During the day it’s too hot and the UV rays are too strong, leaving me without the energy to care for my beloved car. So, I decided to try car care after sunset when the temperature drops. What will happen with car care in the dark, which is considered a no-go by conventional wisdom?
Daringly taking care at night! Having an LED headlamp for camping makes it easier

The current temperature is 26 degrees. It had exceeded 32 degrees during the day, so it has become much cooler. If the temperature were like this during the day, I could take better care of my beloved car... So this time, I decided to do it during the night. I will refresh my beloved car, which has been damaged by UV rays during the day, using Cainz's "Headlight Cleaner" and "Easy Shine Wax".

Even though I plan to do this after sunset, if I can't see anything, I can't do anything, so first, I need to secure lighting. I thought I could substitute with the iPhone's light, but having one hand occupied is inefficient. Therefore, I brought my headlamp (hereinafter referred to as the LED headlamp) that I love to use for camping. This not only frees up both hands but also allows me to illuminate my work area precisely, so I think I can work efficiently.
Refreshing the yellowed headlights with Cainz's "Headlight Cleaner"

First, let's check the "Headlight Cleaner." I haven't taken care of it for about six months, so they have become quite yellowed. This not only looks and feels bad, but also causes poor visibility. To drive safely, we should take care of them regularly.

After washing with water to remove dust and dirt, preparation is complete. Once an appropriate amount is applied to the special sponge, start polishing in both vertical and horizontal directions. Although it takes a little time because you need to polish repeatedly, it is overwhelmingly cooler than doing it during the day, making it comfortable.

With the LED headlamp, you can shine light precisely and check for any unevenness in the application by adjusting the angle, making it easier to see than expected! Since you can see clearly at hand, it might actually be more efficient than during the day. However, it's a bit troublesome that bugs fly towards your face.

Once wiped with a clean cloth, the task is complete. Although the Kainz headlight cleaner is reasonably priced at 498 yen, it seems to be effective. The results of checking whether it has really become clean tomorrow morning will be at the end of the article.

Reviving a sunburned dashboard with Kainz's "Easy Gloss Wax"

Next, I will try the dashboard. There is a room light in the car, but it's colored orange and does not reach every corner, which is a drawback.

When I turn on the LED headlamp, just look at this! The light reaches every corner of the dashboard, making it clearly visible as if it were daytime. With this, it seems like I can take care of it without any issues.

Before using it, wipe the dashboard dry, then spray an appropriate amount of easy gloss wax on a dry cloth and rub it in. You can adjust the amount according to the area you are applying it to, so it’s convenient when you only want to use a little.

You can see how much shinier it is with the LED headlamp compared to before use. The "easy gloss wax" contains UV absorbers, so it's reassuring to regularly take care of it to prevent sunburn.

The result after checking during the day

And then, the next morning. I was excited to check if it was properly taken care of, and when I looked… the yellowing and dullness had completely disappeared. Caring for headlights requires patience, but among the cleaners I've used so far, this one was effective in easily removing the dullness! Since I was able to polish while checking the finer details with an LED headlamp, working at night is surprisingly recommended.

Now, let's take a look at the dashboard. As expected, it has also become remarkably clean. I checked every corner, and there doesn’t seem to be any uneven application! It’s no different from when I applied it during the day.
When it comes to nighttime car care, having an LED headlamp makes it easier to spot unevenness in finer details, so it seems better to carry out the work after it cools down.
