I recommend this mouthwash.

The mouthwash I am using is

This is Gargrin Zero.

I've tried various mouthwash products.

I kept coughing because I was using a strong one, but it was fine after I switched to Gargrin Zero.

There are several types of mouthwash, too.

Zero products are free of alcohol and artificial colors.

I think it's good because it's not irritating!
