It is an alkaline pre-wash used before the main wash. ![AGD Indigo Core Pre-Wash for self car washing](https://img.superchart.com/images/agd-indigo-core-prewash-foam/agd-indigo-core-prewash-foam-01-845vj-900.webp) ![Autogrooming AGD Indigo Core Pre-Wash](https://img.superchart.com/images/agd-indigo-core-prewash-foam/agd-indigo-core-prewash-foam-02-6qr1o-900.webp) The package design caught my eye first. At 800ml, it felt like a generous amount for someone like me who washes their car about once a month. ![AGD Indigo Core Pre-Wash packaging](https://img.superchart.com/images/agd-indigo-core-prewash-foam/agd-indigo-core-prewash-foam-03-xeiiy-900.webp) On wash day, I brought the product to the car wash. It was introduced as a product that emphasizes cleaning power and material safety, and this time I sprayed on the foam myself and checked how things looked after rinsing. ![Autogrooming pre-wash brought to the car wash](https://img.superchart.com/images/agd-indigo-core-prewash-foam/agd-indigo-core-prewash-foam-04-xdghh-900.webp) ![AGD Indigo Core Pre-Wash ready for use](https://img.superchart.com/images/agd-indigo-core-prewash-foam/agd-indigo-core-prewash-foam-05-1nnk9-900.webp) ## What dilution ratios are given for a foam lance and compression sprayer? I opened the product and got ready to use it. The dilution ratios introduced in the original post differed depending on the equipment and how dirty the vehicle was. - Foam lance, normal grime: 1:15–1:20 - Foam lance, heavy grime: 1:10 - Tire browning removal: 1:5 - Compression sprayer: 1:100 ![Opening AGD pre-wash and preparing for car washing](https://img.superchart.com/images/agd-indigo-core-prewash-foam/agd-indigo-core-prewash-foam-06-1itdl-900.webp) ![Alkaline pre-wash being prepared for use with a foam lance](https://img.superchart.com/images/agd-indigo-core-prewash-foam/agd-indigo-core-prewash-foam-07-1pcph-900.webp) ![Preparing to use pre-wash for self car washing](https://img.superchart.com/images/agd-indigo-core-prewash-foam/agd-indigo-core-prewash-foam-08-u8p2b-900.webp) ![AGD pre-wash prepared before pouring into a foam lance](https://img.superchart.com/images/agd-indigo-core-prewash-foam/agd-indigo-core-prewash-foam-09-1al0g-900.webp) I poured the pre-wash into a foam lance, attached it, and used it. The foam-lance ratio was introduced as around 1:10–1:20, but I did not separately record the exact ratio I mixed that day. ![Foam lance prepared with pre-wash inside](https://img.superchart.com/images/agd-indigo-core-prewash-foam/agd-indigo-core-prewash-foam-10-12w7l-900.webp) ![Foam lance for spraying alkaline pre-wash foam](https://img.superchart.com/images/agd-indigo-core-prewash-foam/agd-indigo-core-prewash-foam-11-y9p3f-900.webp) ## Could even a car-wash beginner apply the foam evenly? When I sprayed it with the foam lance, it came out as dense foam. Even though I am not used to washing cars, I could coat the car evenly with foam. As I sprayed, I could faintly smell a cozy fig-and-powder fragrance. ![Pre-wash foam applied evenly to a car with a foam lance](https://img.superchart.com/images/agd-indigo-core-prewash-foam/agd-indigo-core-prewash-foam-12-1fbz8-900.webp) ![Dense alkaline pre-wash foam on a car](https://img.superchart.com/images/agd-indigo-core-prewash-foam/agd-indigo-core-prewash-foam-13-ldp5z-900.webp) ## Did the grime rinse away well with high-pressure water? After spraying on the pre-wash, I left the foam on the car for a little while to loosen the grime. ![Letting pre-wash foam dwell before high-pressure rinsing](https://img.superchart.com/images/agd-indigo-core-prewash-foam/agd-indigo-core-prewash-foam-14-m5kwm-900.webp) After some time, I rinsed with high-pressure water, and the grime washed away cleanly. Once I wiped off the water with a dry towel, the car looked neat and clean, so I was happy with the cleaning power. A family member who used it with me also liked the cleaning power and the evenly produced foam. ## Products - Autogrooming AGD Indigo Core Pre-Wash 800ml — AutoGrooming - 오토그루밍 홈페이지 — 원문에 홈페이지와 구매 링크 안내가 있으나 실제 주소는 제공되지 않았어요. --- Superchart · https://superchart.com/en/@room-at-ease/agd-indigo-core-prewash-foam/ · https://superchart.com/llms.txt
