Hello Everybody.
First at all, I already know and have been reading a lot about there is no chance to clean a Silver Screen, that its only worst.
However, I'm still looking for something that can work.
The silver screen presents a spill of dirty water, that later drains above. It's very annoying. I used to clean similar stains on a White Screen with a rubber, using it very gently, and I'm thinking of trying it here.
Do you think maybe can work or will be a disaster?

Thanks!

I think as soon as you apply any pressure, wiping, you will make it worse. The trouble with 3D screens is that they have a delicate structured surface.
Maybe some of the dirt comes off if you spray some warm distilled water on it. But you need to hold a piece of cloth below that soaks up the liquid. I would inquire at the screen manufacturer before you try.

Applying any sort of pressure will only make it worse, we just had somebody throw soda on our 3D screen, and it’s a mark we will have to bear, as in the past applying pressure to remove the make has only made it far worse, over how much of the screen is the stain you’re referring to?

If it is just dust you might be able to go to the back side of the screen and carefully tap it to knock the dust loose. Any sort of wiping in the front will change the reflective surface.

Yes, unfortunately... Wiping with anything other than a soft dust remover will probably hurt your surface. Then again, we don't know how bad it already looks.

Like Carsten mentioned, warm distilled water might work, if the dirt dissolves in water. And try not to wipe, but tap it off with some cloths if it doesn't come off itself. Tip: Don't use paper towels either. They tend to disintegrate and leave nasty stuff behind.

In case of a water leak you didn't cause yourself, you might even be better off trying to claim a new screen via insurance of the party that caused it.

Chances are the person that done it is long gone.
