Simple answer...........DON'T.

New, muriatic & brick do not belong in the same sentence. Your best cours of action is to go to www.eacochem.com and read everything on their site. Then when you have a question, call them, send pictures and use their advise.
 
Roger Please explain why buddy, this is very important. My first thoughts would HCL would have been reccomended. I'm very interested to hear what you know.

Muratic will burn brick in strong solution. I just turned down a half of mile of brick wall that was acid burned that a previous contractor used muratic on. you need a buffered acid like roger recommended.

What he said :)

There are three companies that make acids specifically for caring for brick:

EacoChem (our first choice)
Diedrich
Prosoco

The reason we prefer EacoChem's product line is that not only is it safe on the substrate you are cleaning........it is also SAFE for the applicator (no OSHA PPE required) We like to keep everything on a job site safe and EacoChem products offer that straight out of the gate.
 
If you know how to us Muratic in a safe way both for you and the brick its the best thing out there for new brick. I've used sure klean 600 also it works good but for some new brick homes It just doesn't cut it. Also depends on mortar and brick color on with product works the best.
 
You'd better know your bricks if you're going to just throw muriatic at it. Some are going to give you a result you never dreamed of.

Brett - we also tried SureKleen 600.....and subsequently rewashed with NMD-80. Kicked it square in the ass. With NMD80, there is NO worry about the color of the brick, if the windows are installed, if lights are up.
 
Oh......and one last tidbit - brick does NOT need high pressure to clean. You'll force too much water into an already porous surface and cause efflorescence.
 
thanks for the info guys. We're definetly going to do some more research. The brick is 70+ yrs old. Very worn. The homeowner (a home rehab guy) is requesting muriactic acid. If we do the job we will have him sign a contract that we're not liable for unwanted results. We're new to the buisness and want to perform at a professional level, so i'm not to confortable working with something that might do more harm than good, thanks again everyone.
 
We had a very strange sighting the other day it was a new constuction house thats very rare around here.Like Roger said knowledge of the type of brick and type of mortor was used will decide what chemicals will be best suited.This house looked like slop and sling brick masons did the work.We used a combination of chemicals.The key to any of the named above chemicals is to get them to the surface at the strength that is recomended.Also preparation is key scrape the heavy tags off with a scraper and get ready to get muddy lol.The guy who helped me is one of the best brick cleaners on the east coast.He has been doing brick for over 25 years,I was lucky to learn from the best.With the cost of these chemicals and labor new brick cleaning getting to be like the dinosuars.
 
CALL LYN regarding cleaning brick that old.

FWIW, you can't waive liability for damages YOU cause. Call a lawyer on that one.
