My Stihl backpack sprayer sepcifically says to empty it after spraying, rinse it, and let it dry. I destroyed another, less expensive sprayer by leaving mixed Killzall in it. Would a plastic gas can withstand the prolonged exposure. I can't always predict how much mixed Killzall I'll need, and I don't want to just waste it.
The recommendation for not leaving mixed solution in your sprayer is not only because it can damage your sprayer, but the solution is not good if left mixed more than 48 hours. Any time you spray you should only be mixing what you will use for that treatment and no more. Anything left over should be disposed of in the proper manner for that product, so if you have to, mix up less than you think you will need to avoid waste.
