As with all product you use, you will only mix up what you need to use and any that is left over needs to be used within 24-48 hours at the most. After that time frame the mixed solution would need to be disposed of as the longer it sits in a mixed states and unable to dry, it will start breaking down the solution and eating away at your sprayer parts.
