Hey I've got some info for ya its long so here we go
first I'm assumimg the brick is more that 45 days old
1.Remove all large mortar particles with hand tools before applying cleaning solutions
2. Mask and otherwise protect adjacent non-masonary materials.
3. saturate wall with clean water
4. use cleaning brush to apply solution (SURE KLEAN LIME AND PUTTY REMOVER TYPE 724) mixed 4 to 6 parts water to 1 part vanitrol
5. allow solution to remain on wall for 3 to 5 min. while brushing
6. thoughly rinse clean
Use a pressure washer to rinse using no more than 80 PSI WITH A 40 DEGREE TIP (I would also call a brick manufacter before using higher pressure)
NOW HERE ARE SOME TYPES OF BRICK see which applies to you
RED BRICK - TEXTURED
RED BRICK- HEAVY SAND FINISH
WHITE, BUFF, GRAY, CHOCOLATE BRICK
SPECIALTY CLEANING
WHITE EFFLORESCENCE
GREEN STAINS
BROWN STAINS
WHITE SCUM-INSOLUBLE
MUD STAINS
PAINT STAINS
MASONARY LAID WITH COLORED MORTOR
If any of this applies to your situation please e-mail me and I can fax you some more detailed info.
hope this helps
