I have a 2007 SUV and I live in an unincorporated fairly rural area so rodents are a fact of life around cars. I have had mice inside my air ducts before and pulling engine insulation into them to build nests. I think I am finally rid of the mice, and now the odor they caused, on top of the "old car" smell that also was there.
I have been looking into a cooling system "flush" product like this for a while, but I don't know anyone who has tried them, so I decided to go with the most expensive product - you usually get what you pay for - and buy the unscented version, as I don't want my car smelling of cheap chemical lemon scent, as so many household products do.
I have to say this has really exceeded my expectations. My car smells odorless now. All traces of mildew, mold, and mice, have disappeared. I plan to flush this product through again once a year. Well done, DWD2 System, for making a good and very useful product.San Diego, CA

Applied this to our Tesla Model 3, and Honda Fit. It really does work as our cars no longer smelled like gym socks anymore.
For the Honda Fit, we did have to drill a small hole under the passenger dash to be able to inject the foam. The package also comes with a plug for the hole you'd have to drill so the air doesn't leak out.
Also be sure to replace the cabin filter at the same time!Atlanta, GA

Leaves no areas untreated
Most A/C evaporator cleaners on the market today are applied through less effective means (i.e. through the evaporator drain). Clean Air Evaporator Cleaner is injected between the blower fan and evaporator core. This allows the air from the fan to push the evaporator foam deep into the evaporator fins, allowing for a superior and thorough cleaning.
