Excuse me, can the rust of leather be eliminated directly by oxalic acid or by other chemicals?

Test a drop of d'Tarnish-1.3 and see if it response, repeat if necessary.

Do a similar test with what you have to see which product response better.

To restrengthen the leather again Fatliquor5.0 is necessary.




Leather DoctorŽ d’Tarnish-1.3: for Pigmented, Aniline, Nubuck, Suede, Hair-on and Woolskin leather types.
This is a pH 1.3 aqueous leather tarnish stain remover.
It’s for removing metal stains like rust, tarnish, some ink and dye including urochrome yellowing effect.
And it’s used as a d’Tannin-3.5 accelerator in the cellulose stain removing process.
