Abstract
Peracid stable fluorescent active compounds in highly acidic, equilibrium peroxycarboxylic acid sanitizing compositions are disclosed as having improved fluorescent stability allowing for monitoring of peroxycarboxylic acid concentration by conductivity and/or optical sensors. Beneficially, the compositions are also low odor and low/no VOC dual functioning acid wash and sanitizing compositions.
