Girl group Rainbow's member Jisook revealed how to refill the window cleanser liquid for cars.

On August 28, Jisook posted on her Naver blog pictures of herself refilling window cleanser for her own car.

In the picture, Jisook purchased her own window cleanser that even men get done at the car shop, refilling it by herself. She taught how to open the hood of the car and how to put in the cleansing liquid, showing off her knowledge about cars.

Jisook said, "I decided to teach it because many women don't know these things."
