I applied the 800 ml product with a pump sprayer at a self-service car wash and rinsed it with high-pressure water before the contact wash.

For this self-service wash, I added a pre-wash step to soak and lift the dirt before the main wash. ![Car with rain and road grime before washing](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-01-iiu0a-966.webp) The product I brought to the self-service car wash was Auto Grooming AGD Cube Wash Line Indigo Core Pre-Wash. ![Indigo Core pre-wash prepared at a self-service car wash](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-02-vchpk-966.webp) ## How were the container and fragrance to use? The container design caught my eye first. Instead of the cylindrical car-care bottles you normally think of, it came in a square cube shape. ![Cube-shaped container of Indigo Core pre-wash](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-03-83gl4-966.webp) ![Purple square Indigo Core product container](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-04-1ehpw-966.webp) The purple-toned container was easy to spot among my other car-care products. It holds 800 ml, and it felt generously sized when I picked it up. Along with the bottle itself, it came with a cap-shaped lid that makes pouring the contents easier. ![Indigo Core bottle and the included lid](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-05-8v7ot-966.webp) ![Cap-shaped lid for pouring the pre-wash](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-06-1pvpn-966.webp) I liked how neatly it lined up when I had several car-care products laid out. ![Cube-shaped pre-wash laid out at the car wash](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-07-z3y7h-966.webp) The product description calls it a FIG & MUSK fragrance, starting with fig and adding iris, rose, jasmine, musk, and amber. When I used it, I noticed a subtle scent rather than the strong smell typical of cleaners. ## What dilution ratios are listed for a sprayer and foam lance? According to the product guidance, the recommended dilution is 1:10–1:20 for a foam lance and 1:100 for a pump sprayer. At the self-service car wash, I prepared it in a sprayer. ![Preparing pre-wash in a sprayer](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-08-1x173-966.webp) ![Pre-wash sprayer prepared for vehicle application](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-09-1vrvn-966.webp) ## What grime did I use it on, and how? Before the wash, the front bumper had lots of bug remains from driving. ![Front bumper with bug remains before washing](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-10-1ryz6-966.webp) ![Front bumper soiled by bugs picked up while driving](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-11-3e5ao-966.webp) There were bugs on the hood and along the sides of the car too. The front and rear windows were also hazy from grime. ![Bug grime on the hood and side of the car before washing](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-12-1lvt8-966.webp) I care a lot about the pre-wash process because I worry about rubbing straight away with a wash mitt while dust or sand is still on the paintwork. Indigo Core is introduced as an alkaline pre-wash that breaks down organic grime such as built-up dirt and bug remains. According to the manufacturer, it does not contain sodium hydroxide. ![Applying pre-wash to the vehicle before the main wash](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-13-1tu5i-966.webp) ![Vehicle pre-wash process using a pump sprayer](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-14-oip0m-966.webp) I sprayed it over the entire vehicle with a pump sprayer. A light musk fragrance spread while I was using it. ![Spraying pre-wash over the whole vehicle](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-15-15ph7-966.webp) I sprayed it thoroughly over the areas with bug remains and debris too. Rather than rinsing immediately after application, I waited a little while to let the grime soak. ![Letting vehicle grime soak after applying pre-wash](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-16-nx58n-966.webp) After letting the grime soak, I rinsed it thoroughly with high-pressure water. ![Rinsing the vehicle with high-pressure water after pre-wash](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-17-p3gje-966.webp) ## How much grime was removed after the high-pressure rinse? When I use a pre-wash, I tend to look closely at how much grime remains on the paintwork after rinsing. This time, I could see that much of the dust and road grime visible before spraying had been cleared away before the main wash. ![Checking the paintwork for remaining grime after a high-pressure rinse](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-18-fd0qb-966.webp) ![Vehicle surface after pre-wash and high-pressure rinsing](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-19-oba43-966.webp) It worked well for first soaking bug marks and stubborn grime that would not come away easily with water alone. Still, a single pre-wash did not remove every bit of grime. I followed it with the main wash using car shampoo and a mitt. ![Vehicle continuing to the main wash after pre-wash](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-20-lgjsh-966.webp) ## What did I like after finishing the main wash? Once I had finished the entire wash, I compared it with the car’s starting condition. ![Checking the vehicle after completing the full wash](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-21-tr9b1-966.webp) Before washing, the paintwork looked slightly dull because of the dust and grime. After the pre-wash, high-pressure rinse, and main wash, the surface was much cleaner and the original look of the paintwork came back. ![Clean vehicle paintwork after the main wash](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-22-cvwbr-966.webp) Removing the grime first and then using the mitt gave me peace of mind while washing. I was pleased to add that extra step before the main wash on a day when the car was especially dirty. ![Vehicle after completing pre-wash and main wash in sequence](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-23-1wi3x-966.webp) After finishing the full wash, I could confirm that the bug remains and grime had been cleared away. ![Vehicle with bugs and grime cleared away after the full wash](https://img.superchart.com/images/autogrooming-indigo-core-prewash/autogrooming-indigo-core-prewash-24-1dfrx-966.webp) In this test, applying it with a pump sprayer was not difficult, and I liked the subtle scent and easy-to-organize container too. For me, it was a worthwhile product for soaking grime before the main wash on a car with lots of bug remains or road grime. ## Products - Auto Grooming AGD Cube Wash Line Indigo Core Pre-Wash 800 ml — AutoGrooming --- Superchart · https://superchart.com/en/@everything-in-place/autogrooming-indigo-core-prewash/ · https://superchart.com/llms.txt
