Mildew & ERNI

Gday, again
I've seen ads for a product called ERNI from Lindner that removes mildew - are they talking of the brown spots usually
referred to as rust or foxing? If so, can anyone confirm if these chemicals are actually potassium permanganate and
citric acid and, if they are, in what concentration?

John:

I doubt that they would give out the formula to allow you to
duplicate it.

There are Two parts to ERNI "mildew STAIN" remover. ERNI A
and ERNI B remove mildew stains from stamps. ERNI A disnfects
and ERNI B is used as a rinse. These are suitable for USED
stamps only. Stamps should not have gum or hinges when
using ERNI Mildew Stain Remover.

Instructions for use:
For the removal of mildew stains you need to prepare three trays
ERNI A (purple) in tray 1, ERNI B in tray 2, and water in tray 3.

It is of course important to prove that the stains you wish to
remove have been caused by mildew.

Place the used stamp, which should be free of gum and hinge,
in the tray containing ERNI A. After about 3 minutes take the
stamp out and when free from drips place in tray containing
ERNI B. After 3 minutes place in tray 3 which contains water
and rinse. Let stamp dry naturally.

It is not recommended that ERNI is used for stamps sensitive
to water of where colours may run. The stamp when placed in
ERNI A will take on a brown colour but this will disappear
when placed in ERNI B.

ERNI A and ERNI B must not be mixed or thinned. After use
the used solution should be washed away with water--do not
put unused solution back into original containers.

There are also waterless solutions for:
Stamp Gum Remover ;
Hinge Mark Remover ;
Stamp Remover for regular stamps (Removes stamps
without water. Gum and existing numbers on the
back of coil stamps will be retained if product is
applied from the back of the paper. ; and
Stamp Remover for self-adhesive stamps.
