Have you ever felt that even when washing your car, 'for some reason, only the glass doesn't get clean'? The 'stubborn water stains' that cannot be removed by simple washing or car washes are a common problem for many drivers.

Especially the white, scale-like stains remaining on the windshield and side windows are not just a visual problem, but also lead to reduced visibility, making them a safety concern that cannot be overlooked. However, many also voice concerns such as, 'even with specialized cleaners, I don't feel any effect' and 'there's a difference in results depending on the product,' highlighting the challenge of not knowing the proper treatment method.

Therefore, to clarify concerns related to car washing, a survey was conducted with 50 men and women aged 30-60 who have washed their cars themselves, themed around 'concerns about car glass dirt.'
