Sadly no this is the correct method. I wish there was a faster way but short cuts in opposition to the directions are unlikely to be effective. There is no way to know you are actually disinfecting or just wasting your time unless you have regular swab tests done and nobody does this I know of anyway. The only way to know you are disinfecting is to follow the instructions. Question, did your Chlorhexidine come with an information sheet? I find the number of people whom have no clue about what the disinfectant does or how to use it alarming. My disinfectants have usually come with instructions so it seems odd that few seem to have read them.
