Start with the most simple thing.
Bring a car duster, available at Wal-Mart or local Pepboys /AutoZone outlet
for $10 - $15.
Dust your car regularly and before a wash.

For washing if u have hose pipe and outlet for the water near the drive way
or somewhere u park the car, u can bring car wash liquid (use it as per
instructions).
Bring Chamois or some white towels (specially for drying the car after a
wash)

Waxing the car after washing and drying a car also helps, but it bit tedious
process. But helps in maintaining the paint of the car.
