MessageI tried sodium hypochlorite diluted 1:10 (laundry bleach) and it blew out my highlights and blackened my shadows. Ugh! Simpler to start again I think. Thanks.

  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...

Regards,
Loris.

What's the formula for cyanotype reducer?
