Urgent: HC110 spilled onto white fabric! Help

[59gilbert]

It's almost dry and I wetted it again. The stain doesn't go away when I rinsed and rubbed under running water for 3 minutes. Can anyone tell me what I can do to remove the stain? I think I may need it chemically remove, since physical rubbing didn't work.
Thanks!

Remember, It's a developer. Did you stop bath? Any developing agents left there will darken in the light.

Is it the concentrate direct from the bottle that spilled, or something that has already been diluted with water?

I would try rinsing the stain with vinegar or other mild acid and water.

Developer is a reducing agent.. though it's probably oxidised by now.

You probably want a reducing bleach (chlorine bleaches are oxidising) I think...

edit: Though if the chemical is washed out, and it's stained fibres by reduction.. then an oxidising bleach may be the way (typical laundry bleach)... hmmm..

Thanks all for your quick responses!!
It's diluted. I finished my film and was pouring away my B solution. Fine, but when I rinsed the container, I turned the tap too much and the water squirted onto my shirt. So what stained it was pretty much diluted.
I kept the shirt wet until now (around 5 hours from when it happened) and I'll try some vinegar first, then the chlorine bleach.
Thanks!!

I don't have the book any more, so I do not know the details, but there are several recipes for cleaning solutions for specific chemicals in The Darkroom Cookbook. I'd go to the library and check it out.

All these recipes for removing developrer stains employ redox-reactions.

Remember, it isn't clean until it's "Oxy"-clean.

Develop it and see if you get your own Shroud of Tourin.

Just wash the shirt by itself as you usually do. If there is any stain try an oxygen bleach rather than Chlorox. There shouldnt be any problem. It does point out that people should either wear old clothes or preferably a darkroom apron when working.
