I was interested in choosing a product by the type of grime, and the cube-shaped bottles felt stable and easy to store in the trunk. Verdict: the clearly divided roles and trunk-friendly bottles stood out. ## Good to know - **Products**: Indigo Core Prewash, Blue Edge Shampoo, Red Resolve Dual Wash - **Role by product**: Indigo Core: alkaline prewash; Blue Edge: mildly alkaline car shampoo; Red Resolve: acidic prewash and shampoo - **Bottle**: Cube-shaped bottle - **Where to buy**: Naver Smart Store product link listed in the original post *Prices as written by the tester on May 4, 2026 · not updated automatically* ## How are AutoGrooming’s three car-wash products divided by role? Unlike washing a car with just one shampoo, I looked into these three AutoGrooming detailing products because I was interested in a setup that lets you care for the car step by step. Their roles are divided into prewash, car shampoo, and acidic care, so you can choose according to the condition of the grime. ![Three AGD products introduced for step-by-step car washing](https://img.superchart.com/images/agd-prewash-shampoo-cube-storage/agd-prewash-shampoo-cube-storage-01-1dzrr-801.webp) ### When do you use Indigo Core Prewash? Indigo Core Prewash is introduced as an alkaline product that loosens stubborn grime, dust, and oily residue before the main wash. I was interested in it as the first step when caring for a vehicle with a lot of built-up dirt. ![Indigo Core Prewash used before the main wash](https://img.superchart.com/images/agd-prewash-shampoo-cube-storage/agd-prewash-shampoo-cube-storage-02-iywmu-777.webp) It was also described as containing no caustic soda, which is said to reduce concerns for coated surfaces, plastic, and aluminum materials. At the time I wrote this post, on May 4, 2026, it was listed as scheduled for release in May. ### What kind of grime does Red Resolve Dual Wash target? Red Resolve Dual Wash is an acidic prewash and shampoo. It was introduced as a product for managing water spots and mineral contamination that do not come off easily with regular cleaning. ![Red Resolve Dual Wash, an acidic car-wash product](https://img.superchart.com/images/agd-prewash-shampoo-cube-storage/agd-prewash-shampoo-cube-storage-03-1d4wq-801.webp) After seeing that it is said to help manage marks left after rain, I thought it would be useful in the finishing stage of a wash. Its listed release date at the time of writing was April 30, 2026. ### What type of car washing is Blue Edge Shampoo suited for? Blue Edge Shampoo is a mildly alkaline car shampoo made for washing with a bucket and wash mitt. Because it emphasizes cleaning power and lubrication, I understood it as a product for the main washing stage, when you wipe the vehicle’s surface with a mitt. ![Blue Edge Shampoo for bucket-and-mitt car washing](https://img.superchart.com/images/agd-prewash-shampoo-cube-storage/agd-prewash-shampoo-cube-storage-04-188zw-774.webp) The lubrication needed to wipe the surface smoothly during a car wash caught my eye. Blue Edge Shampoo was also listed as a product released on April 30, 2026, at the time of writing. ![Blue Edge Shampoo introduced for its lubrication](https://img.superchart.com/images/agd-prewash-shampoo-cube-storage/agd-prewash-shampoo-cube-storage-05-bivqu-810.webp) The lineup I looked at manages major grime first with a prewash, does the main wash with car shampoo, then manages marks such as water spots with an acidic product. Since each product has its own role, I felt it would be easy to choose one for the step you need. ![AGD products for prewashing and the main wash](https://img.superchart.com/images/agd-prewash-shampoo-cube-storage/agd-prewash-shampoo-cube-storage-06-mlyk8-792.webp) ## What features of Blue Edge Shampoo stood out to me? Blue Edge Shampoo was described as having stronger cleaning power than a typical pH-neutral car shampoo. Its mildly alkaline formula, dilution for use, and lubrication were introduced as its main features. ![Blue Edge Shampoo introduced as a mildly alkaline car shampoo](https://img.superchart.com/images/agd-prewash-shampoo-cube-storage/agd-prewash-shampoo-cube-storage-08-1mqwq-774.webp) ![Material on Blue Edge Shampoo’s key features](https://img.superchart.com/images/agd-prewash-shampoo-cube-storage/agd-prewash-shampoo-cube-storage-09-nepc1-864.webp) ![Material introducing Blue Edge car shampoo’s product properties](https://img.superchart.com/images/agd-prewash-shampoo-cube-storage/agd-prewash-shampoo-cube-storage-10-1p5yy-890.webp) ![Material explaining Blue Edge Shampoo’s car-wash features](https://img.superchart.com/images/agd-prewash-shampoo-cube-storage/agd-prewash-shampoo-cube-storage-11-177ij-891.webp) I was interested in the value of diluting it before use and the lubrication that reduces friction while washing. These are features that caught my eye in the product description, rather than results from a direct comparison of cleaning power or scratch reduction. ![Blue Edge Shampoo emphasizing cleaning power and lubrication](https://img.superchart.com/images/agd-prewash-shampoo-cube-storage/agd-prewash-shampoo-cube-storage-12-y6whw-810.webp) ## How was the cube-shaped bottle for trunk storage? The square-shaped bottles stood out in the design. I always worried about bottles rolling around when carrying several car-wash products, but this line was easy to put in the trunk and felt stable to store. ![Square AGD bottles designed with trunk storage in mind](https://img.superchart.com/images/agd-prewash-shampoo-cube-storage/agd-prewash-shampoo-cube-storage-07-1cfd6-792.webp) ![AGD bottles that felt stable to store](https://img.superchart.com/images/agd-prewash-shampoo-cube-storage/agd-prewash-shampoo-cube-storage-13-1ge1d-765.webp) ![AGD cube-shaped bottles that were easy to store in the trunk](https://img.superchart.com/images/agd-prewash-shampoo-cube-storage/agd-prewash-shampoo-cube-storage-14-10e6k-801.webp) Regarding fragrance, there was also information stating that the products use vegan fragrance, are allergy-free, and are vegan certified. These were details I noticed while looking at the products. Overall, the divided roles for different kinds of grime and the easy-to-store bottles stayed with me. ## Products - AGD Indigo Core Prewash, Red Resolve Dual Wash, and Blue Edge Shampoo, 3 products — AutoGrooming - 네이버 스마트스토어 — 원문에 기재된 상품 링크로, 연결되는 제품명은 확인이 필요해요. --- Superchart · https://superchart.com/en/@everyday-textures/agd-prewash-shampoo-cube-storage/ · https://superchart.com/llms.txt
