Firebox has launched "Cyber Clean", described as a "silly-putty-like slime that blots out the muck from every crevice of your keyboards with a grime-slapping antibacterial action".

It has an antibacterial formula that zaps germs inside the goo and changes colour when its effectiveness runs out.

The slime, or as we prefer, stated on the packaging, and presumably the German name, "schmutz-absorbierende", is on sale now for £7.95 a tub.
