Claims12
A method of cleaning a soiled object comprising:
- contacting the object with a neutral or alkaline medium chain peroxycarboxylic acid composition, wherein the step of contacting comprises:
- contacting the object with an acid pH medium chain peroxycarboxylic acid composition consisting essentially of:
- a C8 to C10 peroxycarboxylic acid;
- a C8 to C10 carboxylic acid;
- one or more inorganic oxidizing agents;
- a stabilizing agent;
- a solubilizer;
- and
- an acidulant, wherein the composition is free of short chain peroxycarboxylic acids, and short chain carboxylic acids;
- and
- contacting the object with a source of alkalinity comprising an alkali metal hydroxide to form the neutral or alkaline medium chain peroxycarboxylic acid composition.
