Acid Burn

[mike40]

I went to wash a brownish red brick home. The owner tried to wash it a couple of years ago with hydrochloric acid, he didn't dilute it or didn't prewet the brick, he just stuck a brush in the bucket of acid and went at it. What can I use to clean or remove the staining (Burn) on this brick.

More acid but it is tedious process.

I agree with Ken,try flashing it with hot acid

That will work but if not careful will bring out the efflorescence < spelling > in the brick

Make sure you wear proper clothing and dont forget to protect your eye's

What procedure would I use? What doe's hot flashing with acid mean?
