Tutorial for removing foxing on LD or LP covers.

I already wrote some lines about it, but the pictures were erase by the hosting website.
I decided to create a dedicate page on my webpage about this method. Very effective.

You can find the original page here :
https://retro-visual.jimdo.com/diy-section/diy/

Tutorial :

Old LD or LP has often brown marks on their cover. This is due to the oxydation of little
parts of metals inside the paper or inks. There is a very good way to remove those marks !


This is a chemical experience, made by a guy without any chemical knowledge. (me)
It can be dangerous for skin of breath. Be careful. Open the windows, and don't touch
the liquid directly with your hands !

For this, you need :
- A LD cover with foxing !
- A cotton swab
- Hydrogen peroxide (過酸化水素)
- Ammonia (アンモニア)
- Water

Image

Inside a little cup, add the Hydrogen peroxide. (for one cover, you can add a spoon)
add around 1/10 of ammia (for a hydrogen spoon, you can add 10 drop of ammonia.
add a spoon of water. Mix the solution with a cotton swab.

You can now add gently some of the liquid with the cotton swab on the marks.

I recommand to add it to around ten marks. Then wait 30 minutes like this. You
can then take a humid tissue to wipe it. The action of the solution will continue
after that during some hours. For now, you can continue to add the liquid on other
marks. Waiting for 30 minutes, wipe it, etc... For very hard removing mark, you can
try to add the solution again after 1 hour, on the same mark.

Doing that during the day, near a well lighted window, give more results than doing
it evening. Because the action of Hydrogen is connecting to the light.

Also, never shut or store your LD/LD, with the solution not perfectly dry.
Don't do that on thin paper. The marks will disapear, but the paper will be damage.

you are welcome !
Have fun ! It is very interesting to try just for the experience !
I do it around twice a year for some covers !
You can use the same product for washing yellowed game system. It doesn't come back to white, but it removes lot of marks, and decrease the yellowing color.
