Yea, I just laugh when my friends have all this nice stuff then they start having kids. I have a modest house with basic stuff. Walls were drawn all over, I just paint them. Furniture has paint, markers, things get spilt on it. Daughter thought it was cool to use permanent marker from a drawer on hardwood floors. Didn't come off, will probably have to resurface eventually, but literally who cares. Who am I trying impress? I look at these things as memories and try to fix what I can.
I would like to share that plain original Windex will take permanent marker out of many upholstery fabrics (and some carpets) if applied with a scrub brush and plenty of elbow grease, followed by a washcloth. I would try it on the floors, too, possibly also a Magic Eraser sponge.
Wouldn't wearing a mask while cleaning, and not drinking the stuff avoid that being a problem? Don't have to give kids a bottle of it to sniff while they're making the mess in the first place!
