These range from warm soapy water, household disinfectants, 0.5 % sodium 
Hyperchlorite and of course 70:30% alcohol:water solution (the alcohol used  
varies too)

I also came across a couple of studies regarding the use of Tea Tree Oil 
(Melaleuca alternifolia) and its ability to eliminate conidial spores, (the 
mould typically found in library and archive material). In tests it 
outperformed other solutions such as the ones mentioned above.

Has anyone got any thoughts or experience about using this for decontaminating 
quarantine rooms etc?Obviously it would not be used on the contaminated items 
themselves and would be thoroughly rinsed off the worktops before reuse. I am 
interested because it could be safer for both the user and the environment.
