1. A method of cleaning using an on-site generated peroxycarboxylic acid forming composition comprising:
inputting a user-desired or system-controlled volume or mass of a peroxycarboxylic acid forming composition or peroxycarboxylic acid into a control software for on-site generation;
combining one or more esters of a polyhydric alcohol and a C1 to C18 carboxylic acid, a source of alkalinity and an oxidizing agent at an alkaline pH of at least about 12 in an adjustable biocide formulator or generator system, wherein said system is an apparatus that is insensitive to environmental temperatures of the location of the apparatus and/or reagents comprising a reaction vessel, a series of feed pumps, an outlet for dosing the peroxycarboxylic acid forming composition or the peroxycarboxylic acid from said reaction vessel and a controller for a user- or system-inputted selection device;
generating a peroxycarboxylic acid forming composition without an acid catalyst; and
applying said peroxycarboxylic acid forming composition to sanitize, bleach and/or disinfect a surface in need thereof,
wherein said temperature insensitivity to the environmental temperatures of the location of
the apparatus and/or reagents is controlled by a mechanism for maintaining a controlled temperature of said reaction vessel and/or one or more reagents;
wherein said feed pumps are in fluid connection with said reaction vessel and supply one or more reagents to produce said peroxycarboxylic acid composition in said reaction vessel; and
wherein said reaction vessel is in fluid connection with said outlet to dispense said peroxycarboxylic acid forming composition or peroxycarboxylic acid.
