So I have a customer who have a barn at their plant nursery. When they first started the business, they were using well water, and running it through the sprinklers all around the property.
They have a barn that is completely red from buildup all around it. I’ve tried quite a few chemicals including Luma Brite, CLR, and Iron Out.
A steel wool brush worked well to get it off but I’m looking for a chemical I can spray from a pump sprayer. There are crevices throughout the entire barn and it would take forever to scrub each one. I’m looking for the most efficient way of tackling this job. If anyone has any insight for a situation like this, that would great.
It’s painted aluminum, about 2500 square feet.
About 100 square feet of vinyl siding.
I’m open to light scrubbing if need be but my main goal is to get it clean with a chemical.
Thanks a lot.
