Why did bleach make my rust stain worse?
Sodium hypochlorite (bleach/SH) oxidizes iron and drives the rust deeper. It's the right call on organic mildew and algae, the wrong call on iron stains. Applied correctly, it pulls the iron out of the concrete matrix rather than setting it deeper.
Can you get old oil out completely?
Fresh oil almost always. Old oil, years of drips, will fade noticeably, often dramatically, but may leave a shadow. Concrete is porous and oil migrates downward.
