Unused killzall left in my backpack sprayer has a grey floating growth after a week or two.
Anything I can do to prevent other than empty sprayer between uses?
Answer:
Any diluted solution should be used within 24 hours of mixing for the most effective control and to prevent growth in sprayer as well as prolonging the life of the sprayer. Triple rinse after each use.
