If, like me, you have a laptop keyboard that is encrusted with baked on hand cream, unidentified sticky lumps and a general aged patina that might make the experts on the Antique Road Show look twice, you need one of these Oxo Good Grips Electronic cleaning sticks. it has a plastic wedge shaped cleaner at one end to gently nudge the lumps off in between the keys and a brush to sweep away the remains of breakfast. Now I have one I am OBSESSED with cleaning my keyboard to within an inch of its life. A cheap treat at £5.95 from Lakeland, of course. Buy here.
