I live in a very lovely apartment which features hardwood floors. As floors go they're all right, but you can tell that they've had a pretty long life, with a number of layers of varnish thrown on top of the old ones. Still, when I moved in, the floor was shining and lovely.
It did NOT have an ugly white splash stain on it! Not until I so-carelessly knocked a bottle of rubbing alcohol over. When it first happened, I didn't know I was in trouble: I worried it might eat the varnish a bit, and quickly got some wet towels to rub it up. But when it dried.. oh, when it dried:
No matter how much I rubbed it with soap and water, it kept drying to that horrific tone. It FELT fine to the touch, but clearly the finish was damaged. I dug around on the internet for advice, but didn't get much. One post recommended buying some chemicals to strip the damaged area, and then refinish the floor. Another post recommended using powdered pumice & linseed oil to abrade it. I started thinking .. I didn't have those, but I DID have baking soda and mineral oil. I decided to make a paste and try it out, before starting to muss with chemicals:
It worked!!!! It took a few passes and some elbow grease, but the floor is SO much better. This picture doesn't show the final state - I went over it one more time. If you get your nose down to the floor you might see some faint white spots, but all in all, I'm really relieved.
YAY baking soda & mineral oil!!!!
