Concrete cleaner?

[mcknight77]

I have a rented shop so I can't do what I want with the floor, so....

If I could just get up the oil stains I'd be pretty satisfied for now. It's had 20+ years of use before I moved in so some of the stains have been there a long time.

I've tried three different brands of concrete cleaner followed by power washing. None of them worked worth a hoot, even when using them full strength.

Anyone have any recommendations on a brand that will actually clean the floor?

Tide and water or simple green works great for general purpose. Pour N Restore for Oil Stains that don't come up otherwise

Father-in-law has always used muriatic acid, I think mixed with water, maybe. Swears by it.

+1 for that. Combine that with a floor machine with a green or black scrub pad and you will be amazed at what comes up.

Muriatic acid etches concrete, it doesn't react to nor clean dirt and grime. The acid reacts with the free lime in the surface of the concrete in order to etch it. If it's coated with grease and grime the acid will just sit and do nothing.
