Answer 1

First of all, why are you eating food over your computer? I'm guessing that's how there came to be crumbs inside.

I've been curious too about how to clean to the screen.

Cleaning Your LCD Screen

The major computer outlet stores are now starting to carry LCD cleaners for Flat Panel Monitors and Notebooks that do not contain the chemicals found in some commercial glass cleaners. These cleaners will definitely do the job nicely, but you do have to purchase them. If you do not wish to purchase these factory made cleaners, then you can clean your LCD Screen in the following manner.

What You Can Use

Water.

Water with a tiny amount of soft liquid soap.

Isopropyl Alcohol.

Hexane.

Petroleum Benzine.

Commercial glass cleaners that do not contain ammonia.

What You Should Avoid

Acetone.

Ammonia.

Ethyl acid.

Ethyl Alcohol.

Methyl chloride.

Toluene.

Commercial glass cleaners containing ammonia.

How You Should Do It

You should clean your LCD Screen display by applying the cleaner to a soft, clean cloth. Then you should wipe the cloth across the display from left to right, moving from the top of the display down to the bottom of the display. If your display contains grease or some other contaminant, then you should dampen your cloth with water instead of a commercial cleaner as the cleaner may smear the contaminants across the screen.


General Maintenance

You should avoid subjecting your LCD Screen display to extreme temperatures and humidity and avoid exposures to direct sunlight. You should also avoid physical shocks to your display. If you have a notebook, then you should avoid stacking books or other objects upon the notebook with the screen closed etc.

Answer 3

I have taken keyboards out of laptops and cleaned them using Windex or such, I use glass cleaner on the LCD screen and a soft cloth.
If you aren't up to removing the keyboard, usually you can blow it out with compressed air. You can buy cans of air in the computer section of many stores.
If you clean the keyboard with Windex, let it dry overnight before reinstalling.
