I used it after the disinfection process with K2 foam with heating.
The air conditioning aroma process (lemon scent) was done without the cabin filter, with the air conditioning on full cold and air recirculation active with doors/windows closed. After emptying the spray, I gave it another 5 minutes. Finally, good ventilation and placement of the cabin filter.
The result is amazing, the car smells wonderful and the process is easy and very economical.

It was used after using the same company's cleaner. Pleasant aroma, lasts for a few days. Gives a feeling of freshness. I will definitely prefer it...
