For our experiment I bought a Mildew Stain Remover ERNI A 8070. Its a two bottles, ERNI A + B, which must be used as a complete package for the removal of mildew stains.

We will remove mildew from Penza zemstvo stamp. Should be noted that this stamp was bathed in a hydrogen peroxide from the pharmacy. Spots were cleaned, but not completely disappeared.

The stamp is ready and now looks like this:

Look at the stamp's bottom right corner pictures made by microscope.
