Wood – How to clean dripped paint from a wood floor

Fisrt, DON'T REPLACE THE FLOOR, that would lead to a lot of headaches and is probably un-nessassary. That floor shouldn't absorb oil that quickly if it had been sealed properly. My guess is that the floor either wasn't sealed correctly or it's been so long since it has been that it's all been worn off.

Try getting a wood oil soap (like Murphy's or Old English) these soaps have oils in them that are meant to be absorbed into wood. This won't take out the oil, but it might help to make it blend in. I don't think that stain is comming out, even if you sanded the floor, the stain would have absorbed into the wood too deeply.

It's important to remember that wood is pourous and the natural oils that are in it are evaporated over time and have to be replaced, or else the wood becomes discolored and brittle, which is probably the case here. I wash all my wood floors twice a year with an oil soap to help keep them hydrated.

I think your best bet is to just paint over it/re-paint the wall. On exterior concrete/brick walls it is easy to power wash or sandblast it - the goal is to remove everything. However neither of these will work inside - aside from the mess they'd create, they'd probably take more then just the paint off your walls!

You might find some chemicals to help remove it, but because spray paint is paint afterall, you will undoubtedly damage the paint underneeth it. Permanent Markers can often be removed with Isopropyl alcohol if the markings are relatively new - you might have some luck with this on the spray paint too. However, with markers, generally speaking, the longer you leave it, the more difficult it is to remove.

By the time you get this stuff off, fix the wall, re-paint the parts that need it, you'd probably would have spent more time then just repainting.
