Only with this goo-paste, which is somewhat reminiscent of a the "Slime" from my youth, I really get my keyboard clean.
I clean my keyboard now so every 1-2 weeks with this cleaning compound and my keyboard is pico bello.
The application is very simple. Take "Glibberzeugs" out of the can and with light pressure over the (best switched off !!!) back and forth roll keyboard. If you have the mass rolled once over the entire keyboard, then you can already "read" in the mass its success. Since there is then but one or two crumbs, which one would hardly find out any other way.
I think for the price one can hardly expect better performance. The mass clean my keyboard and I bought it. Therefore ---> Buy recommendation from me.
