First off I took off a star for a leaking atomizer but this stuff actually works as advertised! I've treated my car's internal plastic parts (dashboard etc) and it's been fine, just a LITTLE and then wiping it down with a microfiber cloth. I had to go back with another cloth and wipe the spots towards the end of the application as the first cloth got too wet, but that doesn't argue against this product. I bought a well known product they sell everywhere but this stuff is MUCH better and makes everything look new NOT super shiny like the other product which smells bad, this one has almost no smell and what I smell is good. I will DEFINITELY be buying more from this company. I suspect this bottle will last me at least a few years.
