Hmmmm Rose scent is HEAVENLY!
Scent: Rose, Size: 16 Fl Oz (Pack of 1)
I’ve tried soaps, air fresheners, cleaners, laundry scents from this brand, and from Fresh cut grass, Honeysuckle, Dandelion, Peony, and Rose scents, the last 3 are the absolute winners!! Rose is the latest one I’ve tried and Im in loooooove!! Makes cleaning actually pleasant! 😂
It’s very much like a Rose essential oil scent you get from Aura Cacia if you ever tried. But basically it’s fantastic, not cheap old rose imitation perfume smell. So soft and heavenly!
Not sure about its effectiveness in terms of killing germs, but it leaves no sticky or oily residue. I spray it on countertops, mop the floor with it. One day I was lying on the floor with my legs up and wondering what smelled so wonderful… Then I realized it was the Rose scent from the cleaner. I still use Chlorox products for bathroom sinks, tubs, toilets.
But Rose is absolutely delicious! Mr Meyers, please bring Rose and Peony as laundry scent boosters!

I’m a fan of Mrs. Meyers’ Clean Day
Scent: Apple Cider, Size: 16 Fl Oz (Pack of 3)
I have used Mrs. Meyers Clean Day for years! For me, it works great on my final wipe down, and it leaves a nice fresh scent that fills the room. I really like the Apple Cider scent and I was very happy to see it available in a 3-pack. It is easy to use and does not leave a residue, because I buff the surface with a dry towel after I wipe off the product.

Lovely!
Scent: Rose, Size: 16 Fl Oz (Pack of 1)
Beautiful floral scent. I am very sensitive to strong scents. This spray does not irritate my nose and smells light, like fresh flowers. It does a great job cleaning my counters and leaving them sparkling!

Good cleaner, scent doesn’t last
Have been excited to try this and see how it compares to my previous cleaning solutions. I love the idea of a cleaner that keeps protecting my home for seven days after I clean!
The bottle arrived packed inside a plastic bag, which kept it from leaking on other items in the box. That said, it did clearly leak inside the bag and I had to clean off the bottle before using as it was covered in dried solution that felt tacky to the touch. Tried to show in the photo but not sure that comes through. Anyway, I immediately made a bucket of solution per the directions and headed off to clean. The ratio of 1/2 cup cleaner to one gallon of water makes a VERY sudsy mixture. Not desirable for wiping surfaces or cleaning floors, in my opinion. I’ll use less cleaner next time because the suds were super annoying to deal with and also made me feel like an additional rinse was needed.
A main goal of purchasing this was to use it on my porcelain tile wood look floors and have a long lasting scent, as other reviewers mentioned. I don’t think the scent lasted very long, though I was pleased with how fresh it smelled. It doesn’t smell like a traditional lemon cleaner. The scent is light and fresh and has a sort of herbal or “grassy” aspect to it. My floor seemed quite clean after using this (the mop bucket dump was surprising!) so even though the scent doesn’t stick around for long, I’m pleased with how clean my floor got. Would probably purchase again.
