I am looking for some info on what to use to clean these bleachers up. It’s all aluminum and next to nothing around it I would have to worry about chemical getting on. Below it is just rocks.
I will include a few pics but there is mostly just black algae growth so I was thinking just get a good mix of sh (maybe day if I can get it strong enough) and then do a quick rinse to knock off whatever is left. Is that the best way to take care of aluminum bleachers or would the sh do damage before it cleaned? I have seen where others said they used an aluminum brightener but I wasn’t sure if they had to deal with so much organic growth. Any help is appreciated!
I’m going to be putting together an estimate after I get my process down for sure but if if anyone has done something similar and want to let me know how they priced it that would also be appreciated (by row, sqft, etc). Thanks!
