This single product almost eliminated the daily cleaning headache for my car. With the monsoon deficit, dust is a bigger headache than dirt. This works exceedingly well in removing dust, and saves a ton of time. And not forget, used with a spray bottle with shampoo-water, this combination has saved ~ 200 litres of water a month for me. Basically, I first dust the car with a nylon fibre duster, then spray specific locations with spots/ dirt with the car shampoo-water spray and clean with a micro-fiber cloth. Once that dries, I clean the car with this Jopasu duster. It takes me ~15 min to clean the exterior of my Alto K10, compared to ~30 min for a regular water-based process, and I save ~300 rupees monthly on the local washer. I have used this around 50 times already, the duster is almost black, and it still cleans dust. The instruction sheet says that it can clean up to 250 times. I am inclined to believe that.
