Just wanted to let you guys know that a customer of mine is in love with the smell of NL!!!! She said she wont even use an air freshner no more . Hopfully she will place an order soon!
It has been suggested that the anti-bacterial properties of NL can be extended to killing some germs in the vents by (as kitzy mentioned) spraying some into the vents.
I was cleaning my interior one day, when my neighbor across the street said, "oh my, what are using to clean your car, it smells so good". I laughed, and gave her a bottle for her cars. She loves it.
