Question about coin-op car wash
I saw Spot Free Car Wash website and two nearby my place, I know all about avoiding swirl mark on my car and my car visually none right now. I usually hand wash two buckets but now winter here is getting inconvenient to wash in the cold (know there is waterless but doesn't work on thick dirt/salt). Can I not use the brush from coin-op? I saw on the website they have High Pressure Soap and then High Pressure Rinse just to get dirt and salt off.
Can I just use these two options? The instruction below looks like I have to go through a brush soap... I really don't want that on my car. Here is the instructions: https://www.spotfreecarwash.ca/services
