Stain on school

[Mark 8262]

This is a picture of my son's school. Do you think oxalic acid would remove this stain. There are stains like this all over the building.

Thanks

 

[Larry Hinckley]

Quite likely. A quick test will tell.

 

[A-PLUS]

Yeah, that should do the trick. Like Larry said, do a test spot.

if it doesnt come off, and its not rust it may be red clay, which look similar, and use shurclean, muratic on it

 

[Larry Millette]

I take it they have a sprinkler system? If so then its just Sufur Rust from the sprinklers and ox should remove it with no problems.

Larry, muriatic on light colored brick with a mask test a spot. If the other corners are painted do not use muriatic on that area. You have the right stuff for the painted area. Muriatic has worked well for me on light brick.

Try the Ox and let us know if it does not work, there are some other things that will.

Superior does have more experience than me and he probably knows the best recommendaion or others with many post. I just know what has worked for me and it might not be the best way. After coming back from RT in Alabama i will be more sure of my answere.

Try saferestore from eacochem, it works wonders. It is pricey though.
