New concrete cleaning

A new store going up with new concrete seems like a perfect opportunity to get them off to a great start before cars start dripping oil on everything. But how long does concrete need to cure before pressure washing. Seems like if its hard enough for cars to drive on its hard enough for pw but is that the case?

Depends on how good it was poured , 30 days is a good start. Commercial Grade is usually ready right away. TEST TEST TEST leave the surface cleaner Off for awhile.

And whatever you do be very gentle with it, new concrete will scare easily.

Light chemical lighter rinse.
