Initial rinse with water is doing more harm. You're diluting the foam and it's tested to reduce the results of prefoam. Sticky Snowball doesn't look like it breaks anything down. It's just lubrication. You're likely not loosening up much dirt if that's what it's for.
There's soap like Bilt Hamber Auto Foam and Touchless which are more aggressive but actually break down dirt and road grime in the prerinse.
