This is a place by my shop, they just resealed the asphalt.
I poured alittle water down to confirm what this is. Caustic....
I got burned...
You can use caustic if its a safe mixture, everyone thinks the hotter the better. Until someone is burned, then we are not touching caustics.
I don't have a bunch of time today to answer this yet properly. I will be back later...
Scott Rinsing better might have helped but i'm affraid this is so hot the asphalt seal is gone.
It was brand new...
Change precedure jay.
