I'm wondering if anyone can help me here. I had a wood stain spillage on a new concrete slab yesterday at work. Jammed up to the local hardware and used Mason's Select Concrete Cleaner. It looks like it got about 85 percent of it out. Any one know a way to get a better result? Thank you.

Oh, man, that sucks.
I'd try it again.
Maybe a concrete colour stain for the whole slab.
Hope someone can offer a better answer.
Good luck

It was oil based. I feel like had I thrown a hand full of sawdust on it before I raced to the store, I might have had better results with the clean up. Or better, diatomaceous earth but who has that handy? I will now when I work with oil based paint and stain.

Thanks everyone for your suggestions.

A last resort if there's still a noticeable stain after trying real hard.
Fog coat the general area with the same cement powder diluted down and sprayed thru a garden sprayer with the the tip opened fully. Hopefully, the spill wasn't at foot traffic area.

Any detergent would have been helpful to break it down before it absorbed deeply. On highway spills, Dawn is the agent of choice.

Absorb, break down remainder of it, then remove stain by bleaching color out of the remaining pigment/dye.

I'm pretty sure muratic acid is a bit too strong and will etch too much in to the concrete. I'm going down there today armed with oxalic acid and some powder cleanser to give it another go. Maybe some Dawn as well. I'll report back here so we can all learn from my mistake. Thanks again.
