My concrete walkway is slightly discolored in a 4'x6' area. It was that way
when I bought the house 15 years ago. Don't know what may have caused it
originally. The white spots are burn marks from burning seeds that came off
a burning palm tree.
I have a 1 gal jug of muriatic pool acid. Can I use this acid to etch the
concrete and hopefully remove the blemishes? How should I dilute the acid?
How about using a concrete stain to blend in the irregularities?
