You need clean cotton cloth and Colin cleaner.
First of all remove all the things placed on the table. Clean the dust using the cotton cloth and then drop colin cleaner over the table. With the help of cotton cloth, rub the computer table from top to bottom. You can add more drops of cleaner for getting a shinny look. Dry completely.
I suggest you to clean the computer table twice in a week so that you can receive a fresh environment of working on your computer desk.
