Method of sanitizing and destaining tableware

A method of sanitizing and destaining silverware, said method comprising the step of applying during a rinse step a sanitizing and destaining concentrate composition to silverware at a rate of 100 ppm to 2000 ppm, said sanitizing and destaining concentrate composition comprising:

• (a) from about 1 wt-% to 20 wt-% of a C.sub.1-6 peroxycarboxylic acid;
• (b) from about 10 wt-% to 50 wt-% of carboxylic acid mixture
• comprising acetic acid and octanoic acid;
• (c) from about 3 wt-% to 35 wt-% of hydrogen peroxide;
• and
• (d) a balance of carrier;
• wherein said sanitizing and destaining concentrate composition is non-corrosive and non-filmforming with said silverware.

A method of sanitizing and destaining silverware, said method comprising the steps of applying during a rinse step a sanitizing and destaining concentrate composition to silverware at a rate of 100 ppm to 2000 ppm, said sanitizing and destaining concentrate composition comprising:

• (a) from about 1 wt-% to 20 wt-% of a mixture comprising peroxyacetic acid and peroxyoctanoic acid;
• (b) from about 10 wt-% to 50 wt-% of carboxylic acid comprising a mixture of acetic acid, and octanoic acid, said acetic acid and said octanoic acid present in a ratio ranging from about 10 to 1 to about 1 to 1, respectively;
• (c) from about 3 wt-% to 35 wt-% of hydrogen peroxide;
• (d) from about 1 to 20 wt-% of a solubilizer;
• and
• (e) a balance of carrier wherein said peroxycarboxylic acid comprised a reaction product of said acetic acid, octanoic acid, and hydrogen peroxide;
• wherein said sanitizing and destaining concentrate composition is non-corrosive and non-filmforming with said silverware.
