Here are some tips for effective hand car washes:

1. Use Two Buckets: One for soapy water and one for rinsing your wash mitt. This helps prevent dirt from scratching the paint.

2. Choose the Right Soap: Use a pH-balanced car wash soap designed for automotive finishes, not dish soap.

3. Start from the Top: Wash the car from the roof down, working in sections. This way, you prevent dirt from running down onto already cleaned areas.

4. Use a Soft Wash Mitt: Opt for a microfiber or foam mitt to minimize the risk of scratches.

5. Rinse Thoroughly: Rinse the car frequently to avoid soap drying on the surface and leaving spots.

6. Dry with Microfiber: Use a microfiber drying towel to absorb water without leaving streaks or scratches.

7. Clean Wheels Last: Save the wheels for last to avoid transferring brake dust and grime to the rest of the car.

8. Don’t Wash in Direct Sunlight: This can cause soap and water to dry too quickly, leaving spots.
