Transmission Fluid Removal: Concrete

Hey everyone, we recently completed a driveway wash and everything turned out great, except that our wash revealed some transmission fluid stains that were covered prior to the cleaning. I’ve done some research on removing it from concrete, but haven’t found much. Anyone have any experience with this? Is it similar to regular oil spots? I’ve used CRC Brakleen with great results on oil, but it was raining when we did the wash and therefore too wet to give that a try. Please note that we do not have hot water as an option.

I still won’t recommend it, but I do it regularly, and it works amazingly. I practiced a lot on my shop floor, took me a while bei was comfy doing it on a customers property, but it’s no big deal now. Those look like pretty shallow stains to me.
