How do I clean out a used sprayer?
Someone gave me a really nice two gallon (I think) sprayer that was stored in a shed for a few years. They couldn't remember what they used it for, maybe weed killer. Whatever it was, it wasn't organic.
I'd like to clean it up and use it to spray compost tea.
How do I get it super clean? I opened it up and it was STINKY. Maybe stinky like weed killer, but I'm not sure. I was thinking about soaking it all in vinegar/water, then flushing the sprayer part with vinegar water, and finally flushing it all with plain water.
Any problem with putting white vinegar solution with weed killer (or maybe bug killer?)? I don't want to blow myself up. Or does anyone have any other ideas? This is a nice sprayer!
