Cleaning tire track stains off epoxy floor

[Red_Barn_Garage]

We had our garage floor epoxy coated a few months ago and we love it. However, recently I have noticed some tire track stains coming in a few feet into each bay. For the first several weeks/months, we were able to get the floor perfectlly clean just by rinsing with a hose and maybe wiping with a brush.

Last week when I did this, the tire track marks didn't come off. I then tried scrubbing with simple green and they lightened a bit but are still noticable. Any ideas how to remove the tire marks from the floor without damaging it?

Thanks
