Oh~ I have to introduce this amazing Cyber Clean to you!
It's a "soft yellow rubber" which is perfect combination of viscosity and elasticity. Absorbs dirt and any other residues and kills germs on the surface!
I bought it from Jusco and I have tried to clean it on my notebook's keyboard. From a remote controller to a speaker, it works works works! And it's reuseable & no liquid solutions to clean it.
Let's try to clean with it at a cost of HK$19.90.
