Best All Purpose Car Cleaner for Interior and Exterior
1. Will Koch Chemie Green Star bleach or damage my interior plastics?
No this all purpose car cleaner is completely safe for interior plastics and dashboards when properly diluted. Because it is highly concentrated using it raw will cause chemical burns or white stains. Always dilute it to at least a 1:20 ratio for interior use and never let the solution dry on the surface before wiping it away with a damp microfiber cloth.
2. Can I use Koch Chemie Green Star on sensitive leather car seats?
No you should generally avoid using this strong alkaline cleaner on delicate genuine leather seating. While it can clean heavily soiled leather at a very high dilution it strips essential natural oils causing the hide to dry and crack over time. We highly recommend using a dedicated pH neutral leather cleaner to safely maintain those expensive surfaces.
3. How do I fix white streaks left on my paint by Koch Chemie Green Star?
If you notice white streaks on your paint or glass it simply means the alkaline solution dried before being rinsed or the mixture was too strong. To fix this mistake you must immediately rewet the affected area with a very mild shampoo solution and agitate gently. Rinse the panel heavily with clean water to neutralize and remove the remaining residue.
4. Does Koch Chemie Green Star strip the existing wax off my vehicle?
Yes this powerful alkaline degreaser will significantly degrade or completely strip natural carnauba waxes and synthetic sealants if used at strong exterior dilution ratios. It is frequently utilized by professionals as a dedicated strip wash before paint correction. Do not use it as a weekly maintenance soap if you want to keep your wax layers intact.
