Not if you are careful using electrolysis and muriatic acid. Water and washing powder are pretty benign. Same for a battery charger. The same risk as charging a vented battery at a high rate or with the caps off in a confined area where sparks or open flames are present. e.g. sparking charger clamps, pilot lights, grinding sparks, use of oxy/acetylene cutting torch.
Muriatic acid is a common cleaner used on concrete but care does have to be taken handling it. Rubber gloves, respirator, knowing how to dilute and neutralize it.
