I finally tried the OLAS mouthwash and I love it! it's the most refreshing clean, without the burn of alcohol or the aftertaste of chemical additives. It is one of those items you'll try and then can't imagine you ever didn't use it. It's definitely become a permanent part of my morning and nighttime routines. Love it!

I didn't believe that a non-alcohol mouth wash could truly freshen my breath. This one does it and I am recommending it to family & friends.

My husband and I love Olas. After using it the first time at the Ritz San Francisco, I was in love. I felt it helped my cold sores and the taste is very nice. It’s the kind of taste you just to experience yourself to understand. After using Olas for a while, I gave my old mouthwash a try and couldn’t stomach the harsh alcohol and chemical taste. I hope they never stop making this. It’s just too good.

Love the taste!

I used to love using mouthwash but once I found out about all of the bad stuff in your typical mouthwash, I stopped. But not anymore! This stuff is great-- not too harsh but leaves you with great breath. A perfect ender to brushing/flossing!

Fell in love with this mouthwash from a hotel in San Francisco… it sounds silly but I could not stop thinking about it! Ended up having to buy a lot, and will continue to do so! Nothing has ever made my mouth feel this consistently clean and gargling at night results in almost no morning breath!!

Great travel size! Perfect size for packing in a carryon.

Lean ingredients and clean breath that lasts at least 24 hours. Former Listerine. Tried Therabreath and others looking for a clean wash. This is the answer.

First experienced while staying in Canada. Searched for sources to acquire more. Great clean fresh feeling it leaves in your mouth. I love and have set up a regular subscription for refills.

Store owner replied: Thanks so much for your amazing review! Would love to hear what hotel you found us in?
Super natural tasting product and feels fresh with no chemicals and additives. Glass bottle is good but a bit paranoid about it breaking to be honest: higher price point but great product.

I’ve been using it for over two years and I can’t possibly see my self ever using any other moth wash that’s offered out there. This is such a great product

I switched to OLAS toothpaste and mouthwash after trying it in my hotel room at the Ritz in Tahoe and will NEVER go back to the old stuff. My husband also made the switch after trying some of mine.

I'm all about a natural or healthier alternative to anything. This mouthwash is great. I gave it a shot and now use it daily. I'll be buying a bundle next time.

I first discovered Olas Mouthwash at a luxury hotel in Seville, Spain, and it was love at first rinse! From the very first use, I was hooked by its clean, refreshing taste and the fact that it’s made with natural ingredients—no harsh chemicals, just pure, gentle freshness. It leaves my mouth feeling incredibly clean without that overpowering, artificial burn that so many other mouthwashes have. I’ve been using it ever since and honestly can’t imagine going back to anything else. It’s a small daily ritual that makes me feel like I’m back at that beautiful hotel in Seville. If you’re looking for a mouthwash that’s elegant, effective, and made with care—Olas is it.

We’re first introduced to Olas mouthwash while staying at JW Marriott in Venice. This is the most refreshing mouthwash I’ve ever used. Full of beneficial minerals and alcohol free. It has a very fresh, a bit minty and a hint of herbal taste.

I like Olas because unlike other mouthwash products, it has no alcohol and dye. I am a pharmacist and I really appreciate a product like Olas.
Bertine D. 5/5 Verified
Doesn’t dry your mouth out like some bigger brands. I only discovered this because it was in our hotel room. Now I am a believer. Less of a huge blast of mint, which is fine with me. Good product.
