Reusable cloths are definitely a no-no, microfibre are OK to reuse but must be cleaned after every use . Here it is straight out of HTM 01-05:
6.61 The patient treatment area should be cleaned after every session using disposable cloths or clean microfibre materials – even if the area appears uncontaminated.
This is what HTM says about surface cleaning:
6.67 Cleaning centres on simple techniques using disposable cloths wetted with clean water and a detergent.
It goes on to say that blood spillages should be treatment with a hypochlorite solution.
In our practice we use disposable wipes with a two in one clean and disinfect action.
