Anyone know the best way to remove a dried-in Irn-Bru stain from a rug?

Tried the old soap and hot water, didn't work.

Cheers.




Its made from girders, isn't it?

You'll probably need one of the stain shifters that works with ferrous
oxides.

Ok, doesen't help but the main colorants are Sunset Yellow and Ponceau,
which is a "... red synthetic coal tar and azo dye"

Hmm, good luck in trying to remove that stain then :-(

Actually, Ponceau S (if thats what it is) is used quite a lot in
molecular biology labs because it is an easily _reversible_ protein
stain. Just washes out in water. Slightly acidic works better. And it
may stain rugs better than it stains proteins... Don't know about the
Sunset Yellow though!
