Lye treated floor

Hi I just bought the x50 ultra complete and I love it.

Our floors are lye-treated and requires white soap once a month or so. I know the official specifications say don’t use any other detergent than what we recommend. But I would love if my machine could treat the wooden floor with a bit of my white soap (thinking 5% mixed in)

So my question is - has anyone tried something like this or is it a strict “don’t do that, you will ruin the equipment”? Also if is possible, should I mix it in the soap dispenser or the clean water tank. Please let me know if I am bonkers 😅
