I received this product and used it.
Our car has not been out of the showroom for long, and since my husband enjoys car washing as a hobby, we normally keep it very clean. So I wondered whether a pre-wash would make much of a difference. This time, we tried AutoGrooming Cube Wash Line Indigo Core Pre-Wash at a self-service car wash.

What were the size and bottle design like?
When I opened the delivery box, the bottle design was the first thing that caught my eye. I usually look at function first when it comes to car-care products, but I liked this design enough that I wanted to set it out at the car wash and take photos of it.



It comes in an 800ml bottle. When I first received it, I felt like it would last longer than expected.
What dirt was left on our regularly maintained new car?
Over the weekend, I first checked the car’s condition at the self-service car wash we usually visit. From a distance, it looked pretty clean.


Up close, though, there were bug marks on the front bumper, along with dust picked up while driving and slight contamination on the paintwork. I did a pre-wash before the main wash to deal with these areas.


What changed after spraying on the pre-wash?
First, I sprayed the product evenly over the entire car.


I felt reassured by the description saying it is an alkaline pre-wash that does not contain sodium hydroxide.


After waiting a few minutes, I could see the dirt loosening and running down the car. It made me realize that even a car we maintain regularly still had grime left on it.


Did the high-pressure rinse remove the bug marks and dust?
After letting the dirt loosen, I washed it off with high-pressure water. Even without scrubbing hard, I could see the grime rinsing away.



In this use, the bug marks and dust came off cleanly. After rinsing, the paintwork also felt noticeably cleaner.
How were the paintwork and main wash afterward?
Since the car was already well maintained, I was not expecting a dramatic change. But comparing before and after, the shine looked different to my eyes.




The paintwork looked clearer, and the main wash afterward was much easier to carry out. I was satisfied with both the cleaning process and the bottle design.

What I liked most was how much easier it made the main wash. I could see grime rinsing away even from a new car that usually looked clean.


The process did not feel difficult to me. If you wash your car yourself often or want to clear away bug marks and dust before the main wash, this may be a useful experience to keep in mind.
