    Good stuff

    This is my go to APC for my business. I Use it predominantly on the exterior for Bug splatter tyres etc but also for rubber floor mats. It does the job well 👍

    Product Review

    I've purchased this 10L version. The bottle cap was very tight and couldn't open by hand. Contacted Andrew and he was nice and gave me instruction on how to open it without buying a opener tool. Smells amazing and has this Cinnamon Smell to it.

    Koch Chemie Green Star APC

    I purchased the 5 litre container of Gs. Extremely good value per litre given this is a concentrate - high pH product which can be diluted as desired. This product is now my 'go to' APC in areas that can be thoroughly rinsed as it is so effective.
