Opt for car-specific cleaning products such as car wash soap, microfiber towels, and a soft sponge or wash mitt.
Before applying any soap, thoroughly rinse your car with water to remove loose dirt and debris.
Fill one bucket with soapy water and another with clean water.
Divide your car into manageable sections (e.g., roof, hood, doors, etc.) and wash one section at a time.
Start washing from the top of the car and work your way down to prevent dirt and contaminants from being dragged across already cleaned areas.
After washing, use a soft, clean microfiber towel to dry the car.
Once the car is clean and dry, consider applying a coat of wax or sealant to protect the paint and give it a glossy finish.
