My cat puked on the basement floor in a couple places, but I can't seem to clean the stain. So far I've tried simply mopping with Pine-Sol®, which didn't work. Then I tried scrubbing/mopping with OxiClean™, which also didn't work.
Should I try a cleaner that is specifically designed for concrete?
It's a typical poured concrete basement, that doesn't appear to be sealed. Also keep in mind that it is a basement, so it's indoors and doesn't have great ventilation.
