This is my favorite cleaner! This is a concentrate so it is easy to add it to a spray bottle and mix it with water. I love how it comes with different mixing formulas to fit your needs. The concentrate is a great bang for my buck because it will last me several bottle fills. It is not sticky and smells amazing!

Has a nice fragrance and does a good job and lasts a long time because it's concentrated.

Smells great but sweet so I use a small amount

I like this product because it’s a safer cleaning product. The smell is not overwhelming but I dilute it as I like light smells. Price is reasonable.
