After accessible sources were removed, affected cabin materials were cleaned and dried.

A compatible neutralisation process was then used within its exposure and ventilation requirements. Diffusion can distribute a vapour, but does not prove that every concealed organism has been eliminated.

The operator accepted the cabins after inspection. Continued smoking or new contamination can still cause odour to return.
