methylene blue stains

Hi everyone
A student has dropped a bottle of methylene blue on a new lab floor :crying:
any possible ideas for lifting the stain?

Reduce it to colourless with bleach (or even live yeast) and then soak and scrub with a heavy duty washing powder

Should get it
we had chemical stains on a lab bench, we used 'bar keepers friend' that seemed to be the only thing to shift it. Not very scientific but it did come up clean.

We at the college used it to disinfect slides and noticed it cleaned them too.

Also helped when the chemistry senior smurfed himself and his surroundings...
