This document compares the characteristics of several common sanitizers and disinfectants: chlorine dioxide, bleach (hypochlorites), phenolic compounds, peracetic acid, hydrogen peroxide, and quaternary ammonium. It outlines their microbial effectiveness, typical dosages, contact times, pH suitability, corrosion risks, toxicity levels, environmental impacts, and costs. Chlorine dioxide is highlighted as effective against all microbes even at low concentrations, safe, and breaking down to non-toxic products, though it is more expensive than alternatives. Bleach is noted to form carcinogenic byproducts and be corrosive.
