Misc. Best garage floor cleaners?

[Petescj]

What have you used mostly to get up oil spots on your garage floor? I pulled everything out of my garage and pressure washed the floor but spots didn't come out as well as I wanted.

Thanks in advance

I've had great results with POR 15

EZ way:
try purple power or simple green and let it soak. Sometimes I add a little wd40 in with the simple green in a spray bottle, good degreaser.
Stubborn stains:
Dawn dish soap, if you mix a powder dishwasher soap or baking soda you can make a paste you can scrub with a brush/broom. Scrub it in real good and let it sit under plastic so it doesn't dry, then hose it off.
Also use hot water, real hot, it'll help break things up.
