Need some advice on two questions. What would you recommend for a car wash with extremely hard water and intense sun (Tampa)? It is a constant battle against water spots. I find myself cleaning the car early (7:30ish am) to combat the sun.
The other question is after reading and learning about rinseless wash (was new to me) what would you recommend for the same water/sun conditions? The purpose would be to clean a week long dust accumulation. The car sees about 35-40 miles a week. Thanks in advance.
