  22. 22. Broad spectrum: should have a wide antimicrobial spectrum Fast acting: should produce a rapid kill Not affected by environmental factors: should be active in the presence of organic matter (e.g., blood, sputum, feces) and compatible with soaps, detergents, and other chemicals encountered in use Nontoxic: should not be harmful to the user or patient Surface compatibility: should not corrode instruments and metallic surfaces and should not cause the deterioration of cloth, rubber, plastics, and other materials Residual effect on treated surfaces: should leave an antimicrobial film on the treated surface Easy to use with clear label directions Odorless: should have a pleasant odor or no odor to facilitate its routine use Economical: should not be prohibitively high in cost Solubility: should be soluble in water Stability: should be stable in concentrate and use-dilution Cleaner: should have good cleaning properties Environmentally friendly: should not damage the environment on disposal
  23. 23. Swab Testing Take Swab samples to evaluate the disinfection procedure.
