The haze will wear off shortly! Don't sweat it!
Let's see a pic of the steps!
I don't think the epoxy haze is gonna wear off on its own. That being said, I found that grout stripper sitting on it for like 15 minutes followed by a pumice stone knocks it out. I'll have it all cleaned up in a couple of days and then will sit down and take some good pics. The stair does look nice.
