I recommend this mouthwash product.

I've been using it little by little for about a month, and it's so convenient for situations where it's hard to brush my teeth after eating!

Just 30 seconds really makes the bad breath disappear a lot! It doesn't exactly get rid of garlic smell instantly, but it eliminates it quite effectively, so I like it.

Also, since it comes in a diluted form, I liked that I didn't have to worry about running out even if I used a lot. I bought it in a hurry offline, but it seems like they have sales quite often, so if you buy it then, you probably won't regret it! Honestly, I wondered if it was a bit of a waste to pay full price for a mouthwash like this...? But once you use it, you'll admit it's a great purchase!

Diluting it with water isn't a hassle at all! First of all, since I have to go to the bathroom anyway to spit it out after gargling, it's convenient to just fill a basin with water, and the fact that I don't have to rinse my mouth again is also super appealing.
