for some reason, I have to use eosin as a topical antiseptic and dehydrating agent, which of course leaves persistent spots on my fingers.
Any trick to remove them easily? So far, the only ‘effective’ measure I found is to apply a pad dipped in 37% sulphuric acid. The super acid pH
causes the eosin to turn from rosy to a sort of dark yellow which is almost invisible on the skin. However, not only this is slightly (!) corrosive,
it does not remove the eosin at all, so at the next hand washing what's left of sulphuric acid is drained away and the rosy colour returns in (almost)
full.
Any other suggestion?

sodium thiosulphate comes to mind,
non-toxic/corrosive - worth a try? Keras - 24-12-2022 at 05:47

Would it work? I’m not sure there’s anything to reduce in eosin, really. I’ll give it a shot.Sulaiman - 24-12-2022 at 16:32
I'm thinking more of chelation than reduction.
After posting I did a little googling ;
sodium thiosulphate is used to de-colourise pigments.
eg see 'uses' here https://en.wikipedia.org/wiki/Sodium_thiosulfate
and https://en.wikipedia.org/wiki/Sodium_thiosulfate_(medical_use)
Edit : I'll try to google more before posting in future
