Good points. Just one thing I would add:
The virus is pathetic. It is easily destroyed by soap and water or detergent or indeed almost any cleaning fluid. The instruction to wash your hands for 20 seconds or whatever is to ensure all parts of the hands are washed - you dont need to keep the cleaner in contact for 20 seconds or immerse items unless it is the easiest thing to do. There is a concern less surfaces will be cleaned less frequently due to being over zealous or running out of 'approved' agents. I normally walk around with a disposable disinfectant cloth so that my gloves are continually being re soaked in the cleaner and so every door handle I touch is also touched by the cleaner....Maintenance rags soaked in washing up liquid or soapy water are probably just as good and hold their liquid much longer
