Great in all washer fluids
December 18, 2014
I was skeptical about this at first but I was tired of cheap, ineffective blue washer fluids. One use really convinced me. This stuff really makes a difference. I have used this in the blue stuff, Rain X, and in the warmer months with Einszett windshield washer fluid concentrate (my favorite). It really helps clean more squished bugs and crud off my windshield than plain fluids. and it helps prevent the waxy streaks that Rain X washer fluid typically leaves during the winter months.
Pros:Very effective with all types of washer fluids
