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 :

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


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.

This is very interesting. Obviously, this is an issue that can affect all sorts of paper-based collectibles. It seems to be exacerbated by letting dust collect on the surface, or that is at least my experience.

If we are talking about the same condition, not only are there brown spots, but also actual brown bumps where damage has occurred. You can run your hand along the surface and feel the bumps, right?

I don't know if I have any items where I can try this now. I will just add that prevention is at the top of the order. Dust is the silent killer. You have to be vigilant in keeping your paper items as dust-free as possible.

If you do have aged dusty covers (laserdisc/LP jackets, paperback books), I would recommend simple window cleaner on a lint-free white cloth. Old t-shirts work really well. Spray a spot of the cloth with just enough window cleaner to get it mildly damp*, then with soft but firm pressure, gently wipe the cover clean. The goal is to just have enough dampness to help lift off the built-up dust. You'll see the dust on the rag.

As soon as you finish one section of an item, immediately take a DRY lint-free white cloth, and go back over the areas you cleaned, to get started drying ASAP. For example, use the damp cloth to wipe the front cover, then dry the front cover, before moving on to the next section. Next, do the spines and edges, then dry those. Finish up by then doing the back cover and drying it.

Then, as mimy said, make sure the jackets are completely dry before putting them back in storage. You should be able to get them very dry by your cloth, but let them sit out for bit to finish up.

And if you're going to go through all that trouble in the first place, look into getting some mylar bags to help stave off future cleanings.

* Never, never, never spray window cleaner directly on a cover. You want to use the least amount of dampness when cleaning, and that level can only be controlled by spraying directly on your cleaning cloth first.

Funny I have never had any problems like this in my collection as I store them in a specially made cupboards with doors so light never gets at them and recently I went through my laserdisc collection (very expensive) and found no such issues. Nice to read this fix though should any problems ever arise.

yeah, we are all taking care of our discs, and foxing is certainly not happening in our rooms.
But, it happens a lot when you buy a used disc from persons who find their grand parent's discs in a old crappy and forgotten room, and sell them on ebay, or yahoo auction.
