Funny how protocols vary here and there. On my Fresenius 2008K, we do an acid clean every day, immediately after treatment. This is just to remove and crystallized bicarbonate that may have formed anywhere in the dialysate system, it’s not to disinfect anything. The acid used for this is simply a jug of white vinegar. Then we put the machine in heat disinfect, except the one day a week when we do a chemical disinfect instead (this uses Amuchina, which is just strong bleach made for dialysis disinfection).
