Sprayer cleaning

[Robert799]

I have a small sprayer that I use roundup in. After rinsing it with water... is there anything that I can use to determine if all roundup is rinsed our? I would like to use sprayer for other items and don’t want any carry over.

For gly I flush it couple times with water one of them being hot water if I can if not twice with cold water.

There are tank cleaners/neutralizers, RK, TSC, and coops sell them. I can’t remember what it’s called but I use a pink one. I used to get worried on the first corn spraying of the year, because the last thing in the tank prior was a grass killer for spraying clover plots. I no longer worry about burning up the corn.
