Oral care is Garglin.

I always use Gargrin for oral care.

Everyone has probably used Gargrin at least once, and it's so widely famous and well-known as a mouthwash, right?

I have been using Gargrin since I was young, but when I tried other products, they didn't feel as clean as Gargrin and left a heavy, unpleasant aftertaste, so I didn't like them.
