PPS:
I had good etching results with the help of a 3"x6" wire brush head on
my push broom handle. But I like the plastic sprinkler idea.

2. I too, could never get a good muratic acid etch by brooming, or
mopping.
The acid was "spent" immediately on contact and the result was mottled.
The
solution to the problem was the use of a big plastic garden sprinkler
can .
. .it allows you to get the fresh acid to every square inch of concrete.
Protect all bare metal during this process . . . . the fumes are
corrosive .
. . .use breathing masks but don't trust them . . .use fans to blow
fumes
away.
