It seems its white complicated alps??they have alps writen even you cant see it well in the photo.

regards,

Probably. Picture is too fuzzy to say much more.


You have to take apart to be 100% sure. It's like picking up "women" in some Thai bars.

I guess this phenomenon is common in Ireland too..

So i dismantled part of the keyboard, and the front beige frame is very yellow and i was wondering how can i removed the yellowness or even paint it without damaging the led panel frame and the big horizontal mitac logo. Here's some new photos:

remove them before doing so ?
They seem to be simple thick stickers and likely as those cherry led labels they can be removed and reapplied easily with a thin bladed sharp knife. For the ease of removing applying a little heat might benefit the glue becoming unsticky too.

I don't know what the normal consensus on the subject of cleaning boards with ledlock-stickers still attached, but I dumped mine in warm water with dental tabs, and no visible change on the sticker. I was kinda careful with trying to keep the sticker above water since I too was worried, but failed in that. This was with an AT101.

It looks like Chicony oem.
I wouldn't worry about the logo and lock indicators stickers if you're going to retrobrite. I would try this before resort to vinyl dye or painting. If the glue dissolves you can reglue them.

Yes, i've been reading about retrobrite but i dont know how to do the supposed gel yet. Also, there seems to be two switches a bit worn out, so im thinking of swapping them for new ones if i can find them. Does anyone here sells them?

You don't have to make the gel. It's only for easier applicability to larger items. So if you have a container that fits the board you can use a solution of water and the peroxide

wouldnt that damage the big horizontal mitac logo and the led locks cover?

No it won't harm it, like I said maybe the glue will come out and it falls off. If you are really concerned carefully remove them first with the hobby knife.

Ok, so i only need water and peroxyde? so the other products are for the gel thing?

...and UV light

I use 15% peroxide concentrate paste for hair bleaching, not sure about in you location but probably easy to get from hair salon. Then dilute in water, add in the Oxy laundry stuff and agitate it with a stick then toss in the parts I want to de-yellow and sit it out in UV light for many hours checking and agitate with stick every now and then until it is as white as it is probably going to get. Always handle pieces with stick, tong, rubber glove, etc. Be really careful not to touch it or splash on skin, it can burn.

Will it work if i put it outside on day light?
Also what does the Oxy Laundry contain so that i can find something identical here.

The Oxy cleaner contains TAED
And yes sunlight is fine - try not to do it in the middle of a heatwave though.

If it's too hot I think it damages the plastic. I have used a UV light and sunlight and in my case I found the sunlight more effective (i.e. faster).

Also exercise caution when using hair products as your peroxide source as some of them have additives that apparently will also damage the plastic.

Thanks guys.Ok so It seems pharmacies sell Hydrogen peroxide, what percentage is the best?15%?.
Now i only need to find the Oxy equivalent here and the amounts of water,Oxy and the peroxide.

The Oxy isn't 100% necessary, it speeds up the process dramatically though.
15% would be good - the highest I could get was 6% and it was enough for me but I had to do about 5 or 6 coats - I was using the gel mixture.

It's interesting that you're not able to get Oxy cleaner where you are - it's certainly the easiest way you're going to find TAED.

Imget it, i just need the equivalent here in Portugal. What is it used for?

It's a stain remover or bleacher for clothes. A popular brand where I am is Vanish NapiSan Oxi Action, but if you go to your supermarket and look in the detergents section just find anything with 'Oxy' or 'Oxi' on it and you should be fine.

Thanks. I will check it out. I was just at the retrobright site and they only seem to mention the recipe for the gel.Anyway what about the amounts?

Regards,

I've only ever made the gel and I followed the recipe on their site.
The TAED is something you need to be careful with. You only need a very small amount so perhaps you should experiment with something else that has been yellowed first. I ran my experiment on an old Microsoft Mouse first.

Well i have a good amount of keyboard keys, is the lettering in risk?

There's always an element of risk when you do this, but I think your lettering will be safe.

Found one, lol, it also says Oxi Power, active oxigen and also seems to have some other components including like perfume . I assume its okay to use this?

Should be fine - you only need a very small amount so the additives should have no real effect on the plastic.

okay so i think i can get a 10% peroxyde hydrogen solution, but how much should i use, just enought to cover the keyboard piece?
Also do i need to add water too? or it the one in the peroxyde enought?
