The flint flakes recovered after burial were too dirty to observe residues microscopically and thus some cleaning was required to remove excess soil. Each experimentally used flake was held with a new non-powdered nitrile gloved hand while a gentle stream of ultrapure water expelled from a squeeze bottle with a fine nozzle was used to remove soil. Subsequently, each flake with its associated bag was set out to dry on a tray lined with new cling film. Care was taken to ensure that no samples or bags touched each other.
