Salt and vinegar can be a corrosive combination, which could cause damage to the internal mechanisms of the Chapin Premier 2 Gallon Sprayer (#21220XP), or the tank. However, if cleaned thoroughly immediately after your treatment, you may be able to safely use this combination without corroding your sprayer. For clarification, you may want to contact Chapin product support directly by calling (800) 444-3140 Opt. 1, or by visiting their website's contact page here.
