This is how i clean my car :
1. First I vacuum my car.
2. Apply dashboard dresser, leather upholstery cleaners etc
3. Rinse car with low pressure water.
4. Wash using mitten and car soap [two bucket method]
5. Apply tyre dresser.
6. Again rinse with low pressure water.
7. Decontaminate using Clay bar.
8. Rinse again to remove fine decontamination.
9. Apply Polish [if necessary]
10. Apply glaze.
11. Apply wax/sealant and then buff it off.
Currently I'm using Chemical Guys Deep reflections, so step 10 & 11 is combined.
To answer your doubt. Yes, I have OCD for cleaning my car.
