I thought the keyboard was really clean, that even so the gray dirt, the long term is transferred from the fingers to the keyboard, would be replaced and eliminated. not even close. The manufacturer's promotional video (on its website) says that Cyber Clean "loose dirt" removed. It also aims to kill bacteria (which I can not check). The box does not contain instructions on use. On the manufacturer's website, the cleaning is described as follows: 1. Take the mass of the can and about 10 seconds knead (with trocjkenen hands, that stuff sticks else terrible!). 2. mass lay on the keyboard / phone etc and press firmly to allow Cyber Clean creeping into the interstices. 3. Lift the ground again and folded to have dirt and bacteria inside (so long you slimy mess with dirt and bacteria). 4. mass lay back in the can and this firmly closed (wg. Dehydration risk).
The mass sticks to paper - so you should stay out of it from the Actions pane.
Conclusion: there may be meaningful applications, however, seem to me to keyboard, mouse and telephone a cloth with alcohol and possibly a vacuum cleaner to be more appropriate.
