I'm Martín Golia, and I run Spotless Hacks on my own.
Most cleaning hacks online skip the boring part: how much, how long, and what happens if you mix it with something else. That boring part is what I write down.
Each guide starts from the product label and from official sources like the EPA and the CDC. I draft with the help of AI tools, then check every amount and every warning before it goes up.
I'm not a chemist or a professional cleaner, and I won't pretend to be. If something here is wrong or unclear, tell me: I fix it and update the date.
