Container for using 20% citric acid

Asked July 9, 2018, 2:43 PM EDT

I have used 20% acetic acid as an eco-friendly weed killer. Containers of empty plastic spray bottles worked well. I need to do larger areas and purchased a large hand pump container with a hose and nozzle. It functioned a short time. The same thing happened with a 2nd pump. It seems that the acetic acid is causing a deterioration somewhere. Can you advise about what type/brand of container (2 gallon size) is compatible with acetic acid

20% acetic acid is very caustic and should be used with extreme care. It is corrosive to metal and other materials and is most likely the cause of the problems with your sprayers. There is not a sprayer on the market specifically made for spraying vinegar. Your spray equipment should be cleaned out after each use. When spraying vinegar you should be wearing eye goggles and protective clothing. Also, see the following information,
