Actually alkali bleaches the Cyanotype very effectively but as soon as
the print is returned to acidic conditions it regains its color and
density. Since the effect isn't permanent I wouldn't call it reducer.

I know no Cyanotype reducer (doesn't mean it doesn't exist) but; few
cycles of alkali bleach (weak ammonia, sodium carbonate...) then acid
baths (weak citric, acetic, hydrochloric, nitric ...) will eventually
weaken the image...

Loris.

What's the formula for cyanotype reducer?
