Ilford Washaid is a hypo-eliminator formulated to aid the efficient removal of the thiosulphate byproducts of fixation by ion exchange.
It is particularly useful in speeding up the washing of fiber based papers.
It can also be used to aid the rapid washing of all black & white films and fiber papers saving both time and water. It is particularly useful if a hardening fixer has been used.
Ilford Washaid is a liquid concentrate mixed 1+4 with water for use with either film or paper.
