Rgilliam you would not need to waste the soap why would you need it there is not a painted surface to clean just bare aluminum.The number 1 you use doesnt have hf in it mine does there fore mine would clean it an you probably would have to 2 step to get that reaction not that is a bad thing its just the difference in the chemical make up of the products.The acid you use is more than likely a phosphoric blend with out that nasty hydrofloric in it.
 
Most of the time unless its really bad i just on step and it comes out good there are times that i will just acid it and other times ill do both.But on the bleachers just a good 1 step would get it.
 
Kind of crazy timing for this thread to come back up, we are actually cleaning these bleachers again starting tomorrow. The last time we cleaned them we just used water and a surface cleaner to scrub them down. Left a few stains but they were good with it. They didn't want to use any acids on them because of liability. I am planning on trying just some basic cleaners on them tomorrow just to see if it makes a difference at all. Thinking a little simple green maybe.

if you were to hit it with acid, then hit it with soap, it would neutralize it. Not much of a liability really.

Bingo. It will clean better and be neutralized.

Hot water should be enough to clean it though unless they are looking for brand new then two step is the way to go. You don't need to be very aggressive with the acid either.
 
I have to agree with the acid demands! You will blow their minds with the results! And, acid can be neutralized very easily. You could even use a mild acid and not call it acid! Like many soaps are base but they don't call them a base...
Just get a good mild acid, add a stable surfactant, dwell, and rinse!
 
I had to do the first 6 rows for the local NHL team as the rink got flooded. The stands had to be clean enough to eat off of, so no black tar in anti slip part, and underneath couldn't have any dirt or mud. The e coli count they were looking for was 1 in a billion, you have more e coli on paper money you have in your wallet then that.

We were limited in chems by the consulting company, so we ended up using a straight degreaser, a little brushing and 200 degree water and the stands came out awesome. When I showed up they took between 6-7 hours to do one stand with 10 people involved. Once I showed them how to do things right we cut it down to 1 person a stand for 2 hours max with better results. Remember these were flooded, so mud was every where and took sometime to remove.
 
IMG_0224.jpgBrand new facility at new high school. 18500-19000 Sq.Ft. to be cleaned. Includes visitor stands as well. I am a one man show and with only one PW with hot water. I have never cleaned aluminum bleachers but it can't be to hard. With these Grand Stands being brand new I wonder if just using hot water to clean these would be sufficient. Mainly sticky soda spills and dirt.
