fire damaged concreate

we are doing a demo of a building that burned but they want to keep the slab. the reason the building burt is a car fire. they want us to include cleaning the slab. we have not cleaned the floor of yet but i am guessing it is bad. what would you guys use to get the soot and stuff off the slab? have any of you ever done this before? what works? i was thinking a the 3500psi washer we have at the shop and some muratic acid should do the trick.

never done this before but Im thinking my 6500 would just clean it up lol anyhow fire and crete dont mix, Id say that shiz is brittle and should be ripped out and replaced, If you lay concrete give a bid on replacing it at same time.

I cleaned a fireplace in a house that caught fire once. Not sure exactly what I used. I think it was dnb-1430 from delux. If that didn't work I would try hydroflouric acid or muratic acid. First I would try a lower strength soap and hope to get lucky.
