This product consists of a spray and a heavy cloth. The latter alone already removed all electrostatic deposits. The spray is metered so that nothing runs down, rather the liquid droplets adhere electrostatically, and can be distributed with the cloth without rubbing to prevent any contamination without applying pressure is absorbed by the cloth.
I'm seriously impressed: No more rubbing, and no hassle, so that the sauce does not run in the electronics. And the result is the quality of her a quasi new monitor.
