Miscellaneous Confusing Instructions That Leave Safety Doubts

THIS IS SERIOUS, we are talking about cleaning a car battery that is delicate, the information on the packaging is confusing, it is not known if the cables are removed first for safety or which first, since a step prior to removing one of the cables says throw water and that makes me think of a short that could even damage the computer, it says in step 2 to remove the cables, I'm still worried about throwing water first in step 1, look for a noco video on YouTube where It says about the instructions that leave doubts on the issue of short circuit
Now lastly on the official noco website I see photos in the area of ​​the M401 product which I have where they spray without the cables being connected to the battery (which sounds better to me) and although it seems better to me the whole process in general is confusing, a A serious company should have clear and precise instructions as well as professionals for its products to avoid damage to cars or people.
