This product is very easy to use.
1. Give a small area of the car a few squirts of the dry wash.
2. Gently spread the liquid over the small area with the 1st (provided) cloth.
3. Move onto another area and repeat from step 1, until the whole car is covered.
4. Once you have done that (probably take around 6-7 minutes) the first areas should have dried.
5. Move to each area that you did in step 1 (in sequence) and gently buff/polish it with the 2nd (provided) cloth.
Altogether, it will probably take around 15 minutes.
I did it just over the last weekend on my car that had been for a service and car wash 2 weeks before, and it managed to get a lot of dirt off - the cloths were filthy by the end.
Also, it gives the car a nice shiny water-repellent finish so if it rains you can see the rain forming beads on the car.
This kit has everything you need, which is the bottle of dry wash, a spray attachment, a pair of latex gloves, and two cloths.
