ILFORD WASHAID is a hypo-eliminator formulated to aid the efficient removal of the thiosulphate by-products of fixation by ion exchange. It is particularly useful in speeding up the washing of fibre based papers and is designed to be used with the ILFORD optimum permanence sequences. It can be used to aid the rapid washing of all ILFORD films and fibre papers saving both time and water. It is particularly useful if a hardening fixer has been used.
