Please Help With Advice On Brown Paper Acid Stains...plus

Hello All

I have acquired an old book of 800 +/- stamps dated 1900 and below that has (what I think are) paper acid stains along the perforation edges of the stamps Some of the stamps are so faded that I can not even tell what they are. Others are dirty but not stained. And many of them still have the old envelope paper on back. ( the stamps were just cut around the perfs to make a square for hinging) These are also stained. Some of the stamps seem dry and brittle. Others still have their old glue but the glue is now more like a dark black cracked surface. I soaked three of the more faded, soft and unidentifiable ones in a 3% Hydrogen Peroxide solution, and they just disintegrated.

So my questions are:
01. How do I remove the stains?
02. How can I clean up the dirty ones to keep them from staining if its contagious.
03. Will soaking the stamps in water ( to remove the old paper) destroy stamps with these kinds of conditions?

Also another question.
There are some 1/2 sheets of stamps. These sheets have (what I think is) parchment paper attached to the back of the sheet. This paper has glued itself to the complete backing of the sheet.

04. How do I remove the paper and still keep the glue on the stamps?

Thanks for any advice given.

Sounds like mold and fungus ? Can we see a picture of the stamps still on the original pages ?

Floortrader, Thanks for your reply.

I have already removed most of the stamps from the book.
The book pages themselves tear very easily and on almost all pages the hinged stamps embedded a stain upon the opposite page.
But there are still some intact pages still remaining. (first six photos)

Photos #7 & 8 with black background is of some Mexico stamps already removed.
It shows back and front sides which demonstrates the general overall condition of the stamps within this book as a whole. Some may be worse and some are much better.

The last photos are of the 1/2 sheet parchment paper problem.
