Use Of Disinfectants - Key Notes

  1. Disinfectants should always be used in accordance with the manufacturers' instructions and diluted to the correct strength.
  2. If disinfectants are made up and transferred to another container for use (such as the spray bottles often used to clean down the consulting room) then such containers should be clearly labelled. Bear in mind that freshly prepared solutions are more efficient.
  3. Never use a disinfectant for any purpose other than that for which it is intended. Environmental disinfectants must never be used on the skin.
  4. Never mix disinfectants as harmful fumes may be given off (especially if bleach is used).
  5. Never use a disinfectant of dubious origin or if it has passed its expiry date since efficacy cannot be guaranteed.
  6. Always wear protective clothing when using disinfectants.
  7. Remember that cats are allergic to phenols (e.g. Dettol and Jeyes Fluid).
  8. Some disinfectants are not strong enough to kill acid fast bacteria and bacterial spores.
  9. Bactericidal disinfectants are far preferable to bacteriostats.
  10. The presence of organic material may inactivate disinfectants; therefore dirty areas should first be thoroughly cleaned with a detergent.
  11. Using very hot water can improve the efficacy of a disinfectant.
  12. Always dispose of disinfectants carefully. Never leave buckets, mops and cloths lying around. All cleaning equipment should be thoroughly cleaned and dried before being put away.
