bleaching out the blue completely

Hi, wondering if anyone knew of anyway to completely bleach out part of a cyanotype which was originally a deep dark blue. i have a few sort of "blob) mistakes i like to get out of my borders. i tried oxalic acid (wash), then sodium carbonate, which turned them golden yellow but i'd like for them to go away completely. someone i work with mentioned a weak clorox solution but then there is a risk of bleaching the paper too. i was hoping someone maybe had another suggestion...

thanks! -j

Why not just re-print the image?

I have to agree with Jim. Cyanotypes are pretty cheap and easy to make. I would re-print.
