Yeah, I have had no luck getting the oil stains out of my concrete. Even using acetone leaves a dark spot. I have some HC microbial stuff on the way.

Most 4 post lifts these days have wheels so you can roll them around. You could roll one up to one of those, lift the car up right in front of it and roll it on.

That's true and would work. I had my 2 lifts inline in my old shop and have transferred cars from the back lift to the front one, and vice versa. Rather intimidating doing that 6ft off the floor..:ooo:

Lynn- spent four hours on a small area of my floor, with the Zep citrus cleaner and then the Zep purple degreaser, and still I’m not having much success getting these oil stains out. Did you have any luck with the microbial cleaner?

It did not do as well as I had hoped.

Tony - you might consider renting a ride on floor scrubber. All of the commercial cleaning companies that I've seen use this product with good results use the ride on scrubber. Probably have to make several/multiple passes with it too. This is not a miracle solution if the machine oil has been there for decades though, once it gets into the concrete unless you shot blast the surface (which creates other issues and even then it's likely the stain is permanent) it's not coming out.

Sorry to hear that Tony. Part of the problem is that the oil wicks into the grain structure of the cement so therefore you need a something to get in and remove the oil and then the left over carbon deposits. If you cant live with that then you are looking at light surface grinding, acid etch, and finally an epoxy coating.

Tony, rent a bush hammer and try a sample area where the staining is at it worse. You can go to any depth to see where the staining/saturation ends. As mentioned before, the concrete is porous and most likely soaked in pretty good. If this bush hammering becomes an option, you can rent a scabbler (does a larger area at a time) and do the entire floor and then skim coat it with an epoxy. Good luck.

OK, Tony, time for an update. Been wondering where you are at with this a for a while now. Hopefully, you have done something with the floor and are now building either of your Camaros...https://www.yenko.net/forum/cache.ph...y-emoticon.gif

I’m curious about this shop progress also.
