【Self Car Wash】I want to tidy up before winter comes! 5 types of exterior care categorized by approach
I’m in the car wash cancellation community. But it’s really starting to bother me, the endless water stains, scales, and bug stains I accumulated over the summer… Alright, let’s give it a go before the real winter sets in!
64 out of 100 people are concerned about "summer leftover marks"
Cars that have raced through summer. Strong sunlight, rain, and traces of insects leave seasonal leftovers that are more persistent than expected. In a survey of 100 men and women aged 20 to 60 who own private vehicles, 64 mentioned "water spots, scales, and insect stains."
In other words, what users are concerned about is not just regular dirt. Let's use different items according to the specific worries.

Special products to tackle scales that remain even after washing
Even after washing, white ring-like marks remain on the body and glass. Water spots and scales can be difficult to remove with regular shampoo alone. "Scale Remover Sarupika" is a liquid type that does not use abrasives or compounds. It is applied with a dedicated sponge and then rinsed off and wiped dry.
In addition to the body, it can also be used on side and rear windows, so you can take care of the entire window area at once. Here’s an important point: it cannot be used on the windshield, so for scales on the windshield, a different dedicated product needs to be chosen.

If there’s no shine, add gloss! For whitish resin, go for black.
The "lack of shine" cited by 33 people in the survey can be addressed by changing the finishing method after washing the car. "Hydro Glossy Sarupika" is a glass coating agent that can be sprayed directly onto the wet body after washing. Spread it with a towel and wipe it off, allowing it to cure for about 3 hours. It can be used not only on the body but also on wheels and glass. Being able to progress with the task of wiping off water droplets and adding shine together seems like a nice way to take a breather at the end of the car wash.
To address the whitish appearance of black resin parts that concerned 26 people, there are measures to take. When areas that were originally black, such as around the bumper and the base of the wipers, turn white, it can really make the car look aged. "Return Black Sarupika" is a coating agent that provides a black shine to such resin, rubber, and plastic parts. Spray it onto a sponge, spread it, and allow it to cure for 24 hours. The gloss of the body and the blackness of the resin parts both change the overall visual impression, but the necessary treatments are different.
Iron powder from wheels and yellowing of lights are separate issues.
Finally, I want to focus on the lower part of the car and around the face area. Wheels can accumulate fine iron powder from brakes, known as brake dust, every time they are used. "Wheel Cleaner Sarupika" is a spray-type cleaner aimed at that dirt. Spray from a distance of about 5 to 10 cm, lightly scrub, and rinse off with water. Since it does not use compounds, it is not a polishing type.
Additionally, if the lights are cloudy, polishing the body won’t give a tight look. "Clear Light Sarupika" is a cleaner that does not use abrasives for the yellowing surface of headlights. Spray it on and wipe it off, then finish with the accompanying coating agent. Though the wheels and headlights are small parts, cleaning the surface can change the overall appearance significantly.
The tasks are in the order of "wash," "remove remaining dirt," and "coat necessary areas." Take a look around your car and start with the areas that concern you. For a car wash before winter, that seems just about right... is what I, from the car wash cancellation community, think.
