Motormouth: Adding stuff to windshield washer fluid: Good idea or not?
Q: In some cars that I have used, borrowed or rented, the windshield washer fluid seems slightly sudsy. Do you know of a difference in windshield washer formulation that would cause this? It seems to me that this fluid works a little better.
Can I add a small amount of ammonia to the windshield washer fluid myself to make it sudsy,
