I have been using Anti-Frost for a couple of years because I had problems with OTC washer fluid freezing in the lines. In the past I have also used it in the summer months just because it cleans so well. I would like to try Kristall Klear now that it is warming up. I plan on mixing up a gallon of KK and topping off the reservoir which will still have some Anti-Frost in it. Are there any compatibility problems between the two? When I use Anti-Frost I dilute it 1:1.
I dont think it will harm anything. 1z makes some good stuff and there should be no issue with these two getting mixed.
