ILFORD WASHAID
ILFORD WASHAID is a hypo-eliminator formulated to aid the efficient removal of the thiosulphate by-products of fixation by ion exchange.
Put another way, it can be used to aid the rapid washing of all black and white films to save you both time and water. It is also particularly useful for speeding up the washing of fibre based papers and is designed to be used with the ILFORD optimum permanence sequences.
It is particularly beneficial if a hardening fixer has been used.
