A Tropical Oasis for Your Home: Mrs. Meyer's Magic Pet Odor Eliminator
Scent: Coconut Leaf
Mrs. Meyer's Clean Day Pet Odor Neutralizer in the Coconut Leaf scent has completely exceeded my expectations and become an absolute must-have in my home. As a pet owner, finding a product that truly eliminates odors rather than just masking them can be a challenge, but this spray is pure magic.
First off, the scent is divine. The "Coconut Leaf" is fresh, clean, and subtly tropical without being overpowering or artificial. It leaves my home smelling like a serene, sun-drenched oasis. It's a scent that genuinely lifts your spirits.
What really impressed me, though, is how little you need to use. A single spritz or two in a room is all it takes to banish even the most stubborn pet smells. The mist is fine and wide-reaching, meaning you don't have to douse surfaces to get results. A 12oz bottle goes an incredibly long way, making it both effective and economical.
It's a genuine game-changer, tackling everything from embedded carpet odors to general "dog smell" with effortless ease. If you're a pet owner looking for a solution that's as effective as it is beautifully scented, this is the product you need. It's five stars all the way!

Best smelling spray!
Scent: Orange Blossom, Scent: Orange Blossom
Love this product! It is so easy to use, it has quite a vibrant word sent, which is great if you're trying to deodorize. The size has been perfect. I've probably had this one for almost 2 months now, and we are about halfway done with it. It has worked great on our cat tower, the bed, the couch, and even the rugs. If you feel like you need it, definitely get it. It is so worth it!

“Allergy-Friendly and Fresh—My New Favorite
Scent: Orange Blossom
First off, I have to say that I really do enjoy the variety of scents Mrs. Meyer’s comes out with—though not all of them are my cup of tea! I especially like their seasonal releases. So when I spotted this one, I figured it was worth a try. And honestly, it might be my new favorite scent. It’s pleasant and lightly uplifting without being overly floral, musky, or woodsy in strength — basically, nothing that triggers my or my husband’s allergies. It lasts long enough that can provide freshness for a couple of days in my mind without being so overly strong.
I also appreciate that Mrs. Meyer’s promotes being vegan, cruelty-free, and non-toxic. Like most natural and smaller-batch products, it’s a bit pricier than the big-brand cleaners, but that’s something I can live with—especially when I catch it on sale. I purchased mine at a discounted price, so it was more in line with what I’d spend on the regular Mrs. Meyer’s line in a brick-and-mortar store.
One thing I do fault Mrs Meyers on us their overall bottle design. I don't know how or why, but unless I have some magical gnomes running around my house at night, every single one of these odor room refresher bottles seem to slowly become unscrewed at the top and I can't tell you how many times I have tried to spray and have the bottle become disconnected from the sprayer. Who knows. Maybe it's me and I can't use the spray bottle correctly. So for me I started emptying the this is Meyers room refreshers into one of those continuous spray bottles. Which I think sprays much better than the original Mrs. Meyers bottle. I was just glad it didn't leak in the box on the way here. If I remember correctly it actually was taped down.
Since my kiddos are nice enough not to spray cat urine everywhere and I’m not battling wet dog odors, I can’t say this works any better or worse for pet smell than other scents like Basil or Lemon Verbena. For me, it’s more about the fragrance than the heavy-duty pet odor control or enzymes. If I were strictly deciding based on price, I’d probably just wait for a sale or stick to my other favorite limited-edition scents—like Orange Clove or Mint.

Great Product! Terrible spray mechanism
Scent: Coconut Leaf
This is the best odor neutralizer/air freshener I’ve ever used. 5 stars. And it smells very nice. However, zero stars for the spray pump. I’m not talking about the on/off button, but the fact that in two bottles out of three the pump did not depress far enough to create a spray. I tried everything. (See other reviews) So buy the product but keep your working bottles. It’s incredible that such a well established company can’t spend a few cents more per bottle for a reliable sprayer.
