Zep Inc.

A lot of prepackaged Zep products work well. My issue here is the industrial hand pump sprayer, product code HDPRO1. It has proven to be clog prone and less reliable than very inexpensive dollar store sprayers. I spray two items, wettable sulfur powder and Neem oil for treating my plants. Both do not use any hydrocarbon solvents, they are simply dissolved in water. After using, I flush the sprayer with clean warm tap water. The next time I try to use it, it will become very difficult to pump, and then not spray at all. Meanwhile, the cheap sprayers continue to work, time after time with both the products I use in them. So three sprayers that work for $3 or one sprayer that stops working for $6.00. Not a difficult choice.
