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. Rust needs an acidic product — oxalic acid-based F9 Barc is our go-to. 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. We do what's honest: set the expectation before we start. If a shadow remains and you want it gone, we talk about a concrete stain or a sealer-and-color approach.
