Baird, >From the pictures you sent it appears there is a lot of dirt greases etc on the walls, there also appears to be some rust. Is all the brick on walls? I would approach this job as a cleaning job and would start with a good stripper degreaser. Then if there is rust then use Iron Out or Rust Aid to remove the rust. I would not guarantee the rust to be totally removed. If you want to go to the next step, then try some Masonry Cleaner, remember this is an acid based cleaner, I would dilute to a weak solution, then clean the walls,after that cleaning then rinse with Stonecare Central Neutral cleaner. Do test on an area approximately 4X4 area of larger. Track the time it take to clean that section. Then use that to calculate the time needed to complete the 48,000. Keep in mind you will need to allow time to set up and move any scaffolding you may need to use to clean these areas. What the height of the walls you need to clean? Don't forget to calculate the travel times to and from the job. If you have a profitable pressure cleaning machine there is a wall unit you can use that would work well on these wall. In the futures more pictures would help. the more pictures you can send the better advise we can give. Regards John E.

We are looking at a large project involving removal of stains and cleaning up glazed brick walls in an old school. I am pretty sure some of the yellowing is from old wax. Not sure what some of the other stains are. We are doing a test late next week. Some areas of grout are deteriorating due to water damage, it appears, from the outside wall migrating in. Don't think the custormer is looking for perfection, just a better, cleaner look. Was wondering if anyone has experience as to efficient methodology - equipment, chemicals, techniques etc. This is one of those jobs that is probably open ended enough that I would probably want to bid time and materials. The whole building is 48,000 sf and includes 3 stories of hallways and a large gym. I attached some photos below. Thanks.
