I have read the previous threads and posts about certain chems to take care of this problem. However, if I read right it sounds like it could the efflorescence could easliy come back at any time? If there are cracks, in the cap-stones or mortar, ect. I am still pretty wet behind the ears about the concrete cleaning. I do mostly roof cleaning.

I have attached a few pics of the buildning it is on. Another big factor is that this building is 130 miles one way. The guy owns a huge house that says the roof needs cleaned and so does his guest house. I have also attached a pic of those houses. Just trying get opinions to see if it would be worth the drive to take care of the efflorescence in order to do the roofs and other exterior cleaning around this monster of a house. Thanks in advance for the help,

I'm with you Ron I would send the pics to Eco Chem. It also could be white scum
 
I did a job a few years ago. After it was power washed I sealed it. Sealing it supposedly stops it from coming back. (I was subbed the job from the builder)
 
Mike, Tom is correct it needs sealed. But first it needs cleaned with and appropriate cleaner and NO PRESSURE. Using pressure is only injecting more water in to leach out salts. Cleaner and sealer is not cheap. I just did a quote for such a job and the cleaner and sealer alone were $4500.00
 
Dido what Rob said. Using too high pressure just forces water into the brick and re-engages the source problem. I use HD-80 as well as One Restore (both from eco chem) depending on how much is on the brick. I let it dwell and reapply if needed then rinse with a soap tip for no pressure and just rinse.

Wouldnt it make sense to use a soda blaster for removing efflorescense and calcium since use the correct media intends to not effect the surface being treated? I sent some pics to Eco Chem for calcium build up. After the consultation my confidence level is low. The products they suggest are expensive. They only guarantee me that it will be a tough job. Plus, I think soda blasters are cool. I wanna buy one and blast stuff.
 
Ed I have did a bit of soda blasting in chemical plants and it can be quarrelsome on large scales as well. But you are correct that you would be taking water out of the equation. But until ALL the water has left the masonry units you will soon see efflorescence reappear. But yes soda blasting is cool. I have use metal, walnut shells, black beauty and soda for blasting media. From rail cars, chemical plants, water towers, new pipe uninstalled, installed pipe and lol just about anything that would hold still to blast.

I thought I had mentioned a product in the past on this BBS that I used and had good results on my personal property, no pressure washer required.
