Be careful with electrolytic cleaning, do it in a well ventilated area, and treat any froth build up as an explosive, no sparks, especially electrical ones.

I used to make soap bubbles and burn them in the air. Kept the students amused. Froth is not likely to be explosive as no oxygen is present. Bubbles from electrolysed water can be a different matter – depending on whether the hydrogen and oxygen produced ate kept separate or mixed together.🙂

Hydrogen is so light (density) that it will disperse quite quickly – generally faster than the average DIYer will generate with lumps of steel and acid, so reasonable ventilation is (generally*) all that is required.

* there are always the exceptions, if one really tries hard enough of course.
