It’s ingredients are water, sodium hypochlorite and phosphoric acid.
So it’s basically a weak bleach solution with rust remover thrown in, in a bottle that has some nice bullshit graphics on it.
Although the branded stuff does have “Advanced hypochlorous technology”.
Ok, so that would be a dangerous misunderstanding of the chemistry but you’ve somehow fallen onto the safe (but not very effective) side of the Dunning Kruger trap.
A VERY VERY DILUTE SOLUTION OF THOSE INGREDIENTS Sodium Hypochlorite plus phosphoric acid will give you sodium phosphate and Hypochlorous Acid.
Any more concentrated and you get excess chlorine that cannot dissolve into the water, which forms chlorine gas, which reacts with any moisture like your eyeballs and your lungs to really f*** you up. That would be the nasty side of the Dunning Kruger trap.
Why is “Advanced hypochlorous technology” necessary? Because it’s about 100x more effective as a biocide / fungicide than sodium hypochlorite so works at low concentrations. The aim is to kill the fungus, not bleach your feet.
Why isn’t all bleach just swapped for “Advanced hypochlorous technology” then? Because it’s very difficult to make a shelf stable solution that doesn’t just evaporate to chlorine gas. So you can only get it already diluted and no one’s going to buy 10l of mostly water every time they mop the floor when they can get the same result with a cap full of bleach (which also contains a lot of surfactants to do the actual cleaning but as well).
