How do I clean brick?
We have a high mineral content in our water. It has caused a white haze on our brick. What is the best way to bring the original color back to our brick?

Sounds like you're dealing with efflorescence. Check out this web site, and get in touch with a local distributor of brick/cement supplies. Hopefully this helps...if you need more information let me know!
