KOCHCHEMIE Green Star - Highly Concentrated Universal Cleaner; NTA, Phosphate, and Solvent Free, Clean Auto Interiors and Exteriors, Engines, Commercial, Home, and Industrial Use (5 Liters)

As the title says! Primarily used for my car detailing as a pre-wash and sometimes as the soap itself in-between detailed washes. Spray on, leave for a couple of minutes and gently wash off. Really amazing product!

Very safe, can even wash tires

It’s an over hyped product, does work great as a pre wash but honestly I can use what I was using for exterior for a fraction of the cost and does the same. It’s a over hyped product nothing more nothing less

Best in the industry

This is just simply the best all purpose detail cleaner and can be diluted to all different levels for all different effective purposes. Buy in bulk and cost isn’t too bad since it dilutes

As you know Koch Chemie is an extremely popular company for a reason. This is all you will need for engine bay cleaning, exterior cleaning mixed in your bucket or foam cannon with your soap (diluted of course), attacking bug guts, tree sap, paint contamination, etc on exterior surfaces. Dilute it 10:1 with distilled water and then use 2oz in your foam cannon with your soap of choice and you good to go. This product will remain in my arsenal permanently.

I had the opportunity to use this product this weekend on a 1990 Saab. This car has more things growing on it than my garden has growing.I used the IK Pro 12 foamer and GS diluted 10:1. I formed GS onto the car a section at a time. I let the foam dwell for a few minutes then used a power washer to rinse away the dirt and grime. I had to use a spray bottle on 10 percent of the car as a second pass because the grime was so caked on.This is my new choice of APC for car detailing.

Favorite.
