you will have to give just 30 minutes daily to do it,take about 8 to 10 microfiber towels of a foot square size,pick one at a time and fold it twice you will have 8 faces of one towel now,let start with roof first,dampen the towel a little, start dabbing it gently from front screen (point1) towards back screen(point2),next start again from point 1 to 2 a little more far from your arm approach,complete right side of the roof, go to the left side,do the same,come to the pillars and rear fender and keep unfolding the clean side of Micro Fiber Towel after half of every panel,you will end up dabbing the dust from roof and pillars along with rear fenders in one towel,now this method applies on each part of the car once and you might be ending with 3 to 4 dirty towels.
Pick a new towel again and lightly dampen it with a reputed detailer(i often use spray wax of meguiar's or mothers at this step and some times detailer spray of turtle) and this time start light wiping onto the same portions of the car starting from step 1 to 2 on each panel,on third turn you will be wiping finally.(its a little on the unsafe side but works)
spray sun of a gun on tyres equally good on dirty tyres.
you'r done.
