Caution must be used in making these observations as an accumulation of water in certain parta of the cowling will cause these areas to read higher fol- lowing decontamination than before. (5) The entire procedure above was repeated for a second tine. It hes been fod that if an airersft is thoroughly cleaned in two (2) washings it is impossible to bring the contamSneation level down any noticeable degree by further wash ?
