Best disinfectant for endoscopes is:

Activated 2% alkaline glutaraldehyde is used for decontaminating flexible endoscopes. Advantages  Relatively non-corrosive  Will kill spores with prolonged exposure (3- 10 hours). Disadvantages Toxic. Irritant. Possible alternatives:  Ortho-phthalaldehyde (OPA) peracetic acid.  Chlorine dioxide (ClO2) products (such as Tristel).  Super-oxidized water (Sterilox). Advantages of these newer agents are - rapidly sporicidal, mycobactericidal and viricidal. BUT remember - No agent is clearly superior to the others and a thorough assessment needs to be performed before an alternative agent is chosen.
