## Abstract

This invention relates to a wipe for killing spores comprising an absorbent sheet holding an aqueous composition and a sealed package containing the absorbent sheet, wherein the aqueous composition comprises water, an antimicrobial agent and a peroxide. The invention also relates to a process for killing spores using the above-indicated wipe.

## Claims

### Claim 1

A wipe for killing bacterial spores, comprising:
an absorbent sheet holding an aqueous composition for killing the bacterial spores; and
a package containing the absorbent sheet;
wherein the aqueous composition consists essentially of water;
peracetic acid; acetic acid; sulfuric acid; and hydrogen peroxide; wherein the concentration of the peracetic acid is in the range from 0.005 to 0.08% by weight; the concentration of the hydrogen peroxide is in the range from 0.1 to 0.8% by weight; the weight ratio of the peracetic acid to the hydrogen peroxide is in the range from 0.001 to 0.2; the concentration of the acetic acid is in the range from 0.001 to 0.3% by weight; the concentration of the sulfuric acid is in the range from 0.001 to 0.3% the weight.

### Claim 2 (depends on 1)
