A couple of years ago after a small hand-mixed concrete project some
of the "soup" from the clean-up was spilled on the driveway and never
cleaned up. Now I would like to know the best way to approach this.
Would a pressure washer work (that would be easiest), a sand blaster
(more money and work) or ???

Any suggestions will be appreciated.

Depends how much of a coating there is. If it's just cosmetic,
muriatic acid solution should remove it. Doubt a pressure washer will
work, but you could try. A sand blaster would probably be my choice
for a thicker coating.

If it's chunky you should chip it off with a claw hammer or something like
that and clean up the rest with a wire brush. If you use acid it will for
surely leave a very noticeable blotch or white spot where you use it.

Most tool rental places have various sizes of concrete grinders and
polishers. The results will be far less obnoxious than acid treating
or hackinf at it. HTH

i am thinking that it is a small spot maybe 6" to 1' in dia.
You can use a grinder but be very careful not to grind into the original
concrete .

Thanks all for the advice.

It's acutally a pretty large area --maybe 80 sq feet.
