I have been told by a Micologist, (a mold specialist), that a mixture of 75% vinegar (acetic acid) and 25% distilled water (de-ironised water), will kill mold spores.

Living in the tropics, mold is of a major concern.

Would the above be detrimental to leather if wiped over to eliminate the mold spores during times of high humidity?

I am referring to pigmented and aniline here, in the case of nubuck, it would be lightly sprayed on.

Look forward to your replies.
