I have a couple of the one gallon pump sprayers.
Last Year, I used one of them for herbicides (mostly roundup), and one of them for pesticides. I can’t remember which one is which.
What is a good way to properly clean them so I don’t risk spraying herbicide on something I don’t want to?
I don’t know if running clean water through them a few times would work, I’ve also heard of various products that can be used to neutralize the chemicals.
And no, I am not looking to start a roundup debate here, I just want to know how to clean everything.
