    How often do you wash out your sprayer? I use my sprayer about 2 days a week. Do you guy's wash it out after each app. or do you leave it with whatever you have left in it for next time. I use it for Round up pro only. If I do leave some in there week after week will it cause damage to the internal parts?

    The only type of sprayer that I know of that reacts with Round-Up is a galvanised metal spreayer. To answer your question ... No we don't wash our Round-Up dedicated sprayer out after each use. But, we have a 7.1 water pH here and yours may be completely different.
