I am going to do some rust removal, the back of this house has some rust on the brick from where the a/c was draining. im eventually going to buy some more f9 barc, but until then because of my budget rightnow i have some oxalic acid, would the oxalic work and how should i mix it or is there anything else what about iron out from home depot?

Yes oxalic will work. Just have to play with the mix to get it diluted right

How many pics are you trying to load? I can only do one at a time. Also you might have to have a certain number of posts to be able to load pics, I can't remember.

Ox will work great.

I think you should downstream a mix of soap and grated cheese with hot water. I have a friend who said that worked.
