The phenomenon what you are describing should first be clarified by
a microbiological and chemical sampling. Is it really mold or some
reaction products due to the manufacturing of leather?

In our practice, the use of latex sponges (Wallmaster sponge) have
proven themselves effective in cleaning up some contaminated

If a "film" of mold was carefully removed, this doesn't come back so
quickly without sunlight under really good conditions < 60% RH on
the surface. Ergo, this seems to be a chemical problem.

Caution: Don't use any disinfectants, which can catalyze the
problem. I recommend the consulting with a conservator of leather

If you have more questions, so I am like available.
