Liquid behind laptop LCD

[Grant]

I am about to lend a mate an old MacBook Pro that has been sitting in a cupboard.
It was looking a little grubby from dirt / dust etc, so I thought "let me give it a quick cleaning".
I have done this on a regular basis on other laptops of mine, but today, the damp cloth - was a little too damp.

So now there is moisture behind the LCD, it kind of resembles what a patch of oil would look like - but without the colours.
The question in this, are there any easy suggestions as to how best get it dry (without taking apart the entire screen).

The LCD is functioning perfectly - it's just the damp patch sitting there that has to go.

Perhaps try the rice trick? Alternatively, Builders Express sell these little things that look like a tupperware container that draws the moisture out of just about anything

i fear it may be a little large for the rice trick.

i suspect i may have to take the lcd apart

I would try the rice trick first, although you need a whole lot of rice.

Don't think you can take the LCD apart, depends how old it is as some of the newer ones the LCD is "welded" to the glass.

Next time make the cloth wet and squeeze it dry enough first, never put liquid directly onto the screen.

Benzine works better and evaporates instantly.

it's an oldish macbook pro. screen can be taken apart, done it once before - but a ball-ache of note.




Having said all this, it's evident i'm having a bad water day.
Went to the kitchen to get something to drink and i hear splashing coming from the laundry.
Turns out, something has happened to the washing machine's outlet pipe, and it has been merrily doing the washing but dumping all the dirty water on the floor.
Best i find some water-wings before i go back in there.

Eish dude.

Same has happened to me and fortunately it didn't make it to the wooden floors.

Right.
So I have decided to bake the thing.
I have removed the screen from the body of the laptop, but have not taken apart the screen.
Popped it into the oven. Fortunately my oven can be set to 80 degrees, so it in there with a temperature / meat probe connected to the oven itself, along with another thermometer (just in case), and the oven door about a quarter open.
The temperature inside the oven has been fluctuating between about 40 to 50 degrees with the door open.
The oven is a thermofan job with 2 fans, so it is circulating the warm air quite nicely without creating any "hot spots".
I pulled the screen out after 15 mins, and the damp spot is now half the size.
Going to turn the oven off now, close the door & allow the fans to run for the next 20 mins or so.


Stay tuned for the next riveting installment - this kill or cure

That worked out rather well.
My main concern was the moisture trapped inside the screen.
There is a small water mark / stain which is barely noticeable, except to me - I am unable to take my eyes off it.
The patch of liquid was originally about 5 x 8cm. The stain / residue has been reduced to around 2 x 2 cm, but it is very feint (except to my eyes - it may as well be day-glo orange).
