Hi
My understanding, from reading a lot, is that it is the surfectant in soap which causes the virus to break down. The virus has a fatty coating, and the soap can break this down, and therefore the virus apart and thus deactives it.
So soapy water will do the job. There was an interesting article on the BBC which showed that wiping your phone\tablet down with soap, then with a micro fibre cloth was really good at removing pathogens ( the microbiologist demonstrating used some gadget thing to measure before and after)
