"Reducing properties
In the presence of other oxidizing agents, hydrogen peroxide acts as a
reducing agent. This is because it can take up an atom of oxygen to give
water and oxygen gas.
It reduces silver oxide to silver.
Ag20 + H2O2 ----> 2Ag + H2O + O2"

## Looks good and shows a difference in reaction between Ag2O and
AgO.......2 of the five forms of silver oxide.
H2O2 will reduce Ag2O into metallic silver and make AgO out of metallic
silver.
..clean a black electrode, then make it black again.

From
http://www.h2o2.com/applications/industrialwastewater/photowaste.html:
"Silver Recovery
Ionic silver is precipitated by hydrogen peroxide primarily as metallic
silver. The reaction is:
2 Ag+ + H2O2 ----> 2 Ag0 + H2O + 1/2 O2
The weight ratio of hydrogen peroxide to silver, based on the above
equation, is 0.15 to 1.0. Tests have shown that the silver content can
be reduced to less than 0.1 microgram/L using hydrogen peroxide
treatment."
This following links do not add much to the question of what actually
happens when you combine H2O2 with CS but they are informative:
