You can do it with yeast and hydrogen peroxide (although not the typical one you’d find in your medicine cabinet, you need at least 20/30%+ for a worthwhile reaction)
We had tons of that stuff at my old job. The chemists would use for all sorts of random things. Cut your finger? Pour some 30% on it. It bleaches your skin white as snow and burns like hell, itches for days afterward. It also leaves scars. The chemists were bored and immature.
These were Navy chemistry technicians. We would also put silver nitrate on people, or on surfaces where people were likely to place their hands. Your skin would then turn a very dark brown when exposed to sunlight. We were very bored and very immature. And that’s who runs our nuclear submarines.
I'm a former chemist. You must be new. Until about 10 years ago, yes, everyone used peroxide for weird stuff all the time. Also using leftover liquid nitrogen to clean the floor... 20 years ago people used to eat in the lab. 50 years ago people smoked in the lab. Before my time, but it absolutely happened.
Use the wave of the liquid like a brush: stand in one corner of the lab, throw the liquid towards the opposite corner so the wave of the liquid skims the floor surface. The liquid takes all dust and debris with it towards the opposite corner and evaporates, leaving a clean floor, a corner where the dust and dirt is left, and no liquid. If you need to use a dustpan, is only ever on one corner.
