Its three products divide jobs between old grime, water spots, and bucket mitt washing, rather than presenting actual wash-test results. Verdict: The clearly separated product roles make this lineup easy to understand. ## Good to know - **Product lineup**: Indigo Core Prewash, Red Dissolve Dual Wash, and Blue Edge Shampoo - **Indigo Core Prewash**: An alkaline prewash introduced for loosening contamination before the main wash - **Red Dissolve Dual Wash**: An acidic prewash shampoo introduced for water spots and inorganic contamination - **Blue Edge Shampoo**: A mildly alkaline car shampoo for bucket mitt washing - **Container**: Square containers with the Cube Wash design *Prices as written by the tester on May 9, 2026 · not updated automatically* ## How are AG Detail prewash and car shampoos divided up? I was interested in detailing washes where you choose products based on the paint condition or type of contamination. AG Detail is a brand Auto Grooming introduced for people who want a more finely divided car-wash routine. ![Introduction to AG Detail products for detailing car washes](https://img.superchart.com/images/agdetail-prewash-car-shampoo-lineup/agdetail-prewash-car-shampoo-lineup-01-1e8mi-966.webp) What stood out in the product introduction was the explanation that it considers not only cleaning power, but also the paintwork and coating layer. ![Auto Grooming AG Detail car-wash product lineup](https://img.superchart.com/images/agdetail-prewash-car-shampoo-lineup/agdetail-prewash-car-shampoo-lineup-02-mvnsm-966.webp) The lineup has three products: Indigo Core Prewash, Red Dissolve Dual Wash, and Blue Edge Shampoo. I liked how it separates alkaline and acidic products, as well as the prewash and mitt-wash stages, so you can choose according to the contamination. In this post, I have gathered the product descriptions and what I expect from them rather than actual car-wash results. ## What is Indigo Core Prewash for old grime? The product I personally looked forward to most was Indigo Core Prewash. It is introduced as an alkaline prewash that loosens stubborn contamination, road dust, grease, and bug remains before the main wash. ![Introduction to AG Detail Indigo Core Prewash](https://img.superchart.com/images/agdetail-prewash-car-shampoo-lineup/agdetail-prewash-car-shampoo-lineup-03-13u5v-966.webp) When I think of strong alkaline products, I worry about their effect on coating layers, plastic, rubber, and aluminum wheels. The product description says it does not contain caustic soda and that safety for these materials was considered. This is not a hands-on result confirming safety on an actual vehicle. ![Guide to the features of Indigo Core alkaline prewash](https://img.superchart.com/images/agdetail-prewash-car-shampoo-lineup/agdetail-prewash-car-shampoo-lineup-04-9o1ws-966.webp) It caught my interest as a way to loosen contamination on a vehicle with heavy old grime first, then move on to a car-shampoo wash. ## How is Red Dissolve Dual Wash different for water spots? ![Introduction to AG Detail Red Dissolve Dual Wash](https://img.superchart.com/images/agdetail-prewash-car-shampoo-lineup/agdetail-prewash-car-shampoo-lineup-05-hfxl2-966.webp) Even after washing a car, the water spots left after rain can quietly bother you. Red Dissolve Dual Wash is introduced as an acidic prewash shampoo focused on removing these water spots and inorganic mineral contamination. ![Guide to the features of Red Dissolve acidic prewash shampoo](https://img.superchart.com/images/agdetail-prewash-car-shampoo-lineup/agdetail-prewash-car-shampoo-lineup-06-7tc7x-966.webp) I found the sequence of following an alkaline prewash with an acidic product interesting. I expect it could help manage water spots, but I have not confirmed its removal performance firsthand. ## What does Blue Edge Shampoo focus on for mitt washing? ![Introduction to AG Detail Blue Edge mildly alkaline shampoo](https://img.superchart.com/images/agdetail-prewash-car-shampoo-lineup/agdetail-prewash-car-shampoo-lineup-07-1wbm5-966.webp) Blue Edge Shampoo is a mildly alkaline car shampoo for bucket mitt washing. According to the product description, it was designed to boost lubricity along with cleaning power, reducing the friction burden during mitt washing. ![Guide to the features of Blue Edge Shampoo for mitt washing](https://img.superchart.com/images/agdetail-prewash-car-shampoo-lineup/agdetail-prewash-car-shampoo-lineup-08-11bx3-966.webp) Since fine scratches are a concern when washing a car myself, the explanation about lubricity caught my eye. The combination of loosening contamination with Indigo Core Prewash and then mitt-washing with Blue Edge Shampoo seems like it could be useful for managing old grime. ## Which product combinations are introduced for different contamination? What interested me about this lineup was that the product combination changes depending on the nature of the contamination. The suggested flow is as follows. - For heavy old grime: Indigo Core Prewash → Blue Edge Shampoo - For severe water spots or mineral contamination after rain: alkaline prewash → Red Dissolve Dual Wash ![Guide to AG Detail car-wash product combinations by contamination](https://img.superchart.com/images/agdetail-prewash-car-shampoo-lineup/agdetail-prewash-car-shampoo-lineup-09-5axdg-966.webp) For several kinds of contamination together, including old grime and water spots, the introduction suggests using Indigo Core Prewash → Red Dissolve Dual Wash → Blue Edge Shampoo in that order. It is not a routine I have compared firsthand, but separating the role of each product by contamination made it easy to understand. ## What stood out about the container design and scent? The square container with a design called Cube Wash also caught my eye. Judging from the shape alone, it looked stable for stacking or storing and good for using space efficiently. ![AG Detail Cube Wash square container design](https://img.superchart.com/images/agdetail-prewash-car-shampoo-lineup/agdetail-prewash-car-shampoo-lineup-10-1e3wd-966.webp) ![Square containers for AG Detail car-wash products](https://img.superchart.com/images/agdetail-prewash-car-shampoo-lineup/agdetail-prewash-car-shampoo-lineup-11-lptra-966.webp) The scent interested me too. The product introduction says it uses a vegan fragrance certified by the Korea Vegan Certification Institute. Using a nicely scented product while washing a car tends to make the experience more satisfying for me, so I was curious what it would smell like. ## What was I most looking forward to after seeing the lineup? ![Introduction to the launch of AG Detail prewash and car shampoo](https://img.superchart.com/images/agdetail-prewash-car-shampoo-lineup/agdetail-prewash-car-shampoo-lineup-12-6oopw-966.webp) What I looked forward to most was how the prewash and car shampoo are divided according to contamination and wash stage. ![Introduction to Auto Grooming AG Detail car-wash products](https://img.superchart.com/images/agdetail-prewash-car-shampoo-lineup/agdetail-prewash-car-shampoo-lineup-13-nuwfk-500.webp) There were several points to look at, from the alkaline-versus-acidic distinction to lubricity, fragrance, and storage shape. However, this post does not include test results that would evaluate actual cleaning power, the degree of water-spot removal, or how the products feel during mitt washing. ## Products - AG Detail Indigo Core Prewash, Red Dissolve Dual Wash, and Blue Edge Shampoo — AutoGrooming --- Superchart · https://superchart.com/en/@the-laundry-line/agdetail-prewash-car-shampoo-lineup-b900/ · https://superchart.com/llms.txt
