I am flushing my cooling system with approx 80% water and approx 20% detergent – specifically LA Awesome cleaner.

Filled it yesterday and will drain tonight. But I will not be able to drain it completely -- and honestly don’t want to since the car runs significantly cooler with the soap reducing water’s surface tension.

So, for the soap residue that is left behind (which should be small) will there be any negative reaction with Zerex G05?
