If you want to clean your touchscreen, follow the set of instructions given below.

Shut down the system, then unplug the power cable from the power source.
Touch a metal component in your casing to remove any static electric charges from your system. This is essential to prevent yourself from getting electrocuted or your device from getting damaged.
Apply your cleaning solution to the rubbing cloth. Note that you're not supposed to apply the cleaning solution to the screen directly. This is essential to prevent the cleaning solution from getting attached between the thin layers of the touchscreen, which can cause black spots to develop on the screen.
Wipe the touchscreen gently in a circular manner from the center of your touchscreen. This will eliminate any dirt or any residual particles in the touchscreen. Stick to the circular motion to prevent the formation of irregular lines and patterns on the touchscreen while cleaning.
Dry off the screen by using an appropriate piece of cloth. We recommend using a dry microfiber piece of fabric. Some materials, such as paper towels, can scratch the touchscreen if used to dry off; therefore, you should avoid them.
If any residues are left between the bezel and the screen, we recommend using a soft brush to wipe them off.
Leave the touchscreen to completely dry before you plug it back to the power source.
You can now turn your device back on.
