I was working in my basement studio and a piece of acrylic punctured a red Krylon outdoor paint spray can which exploded onto the unfinished concrete floor, concrete walls, metal cabinets, and wooden backsplash. I am renting and thus need to clean the spray paint and have read that I can use turpentine or rubbing alcohol to remove the paint. What would be the best to use given the items I have to clean (concrete, wood, and metal)? Thanks!
Forget turpentine and rubbing alcohol. Whatever you do, you will have to refinish some of the surfaces.
For everything other than the concrete you should be ok with acetone. Use steel wool soaked in acetone to break the gloss of the solid areas of paint (being careful not to scratch the metal and to go with the grain of the wood) and then lots of acetone and clean rags. If the rag isn’t wet anymore, dip it in acetone again. Repeat. Wear chemical resistant gloves and a vapor rated gas mask.
Regarding the concrete: once the paint has cured (24 hours) try to chip it off with a chisel. Use a wire brush as last resort. If you use acetone, you will actually make it worse. Once you’re done, consider renting a floor buffer and use tinted floor wax to refinish the floor. For the walls do a similar preparation and then paint.
Dispose of the rags by bringing immediately to a hazardous waste treatment facility or burning in a safe and controlled environment.
DO NOT KEEP THE RAGS INSIDE THE BUILDING

If you end up getting your hands on xylol or toluene - use excessive caution, as the fumes are carcinogenic and the fluid is caustic.
