The whole hallway smells like a nursery is sending me because I did the exact same thing last year, except I used way too much and my stairs turned into a slip and slide for a solid week. My wife walked down in socks and almost ate it, so now we just live with the squeak and pretend it adds character. Baby powder seemed so smart at the time, like a life hack from the internet, but it just works its way into the cracks and gums up worse than before. Did you ever get the smell out or are you stuck hosting playdates you didn't plan?
