Rusty mess

Just some past pictures of some irrigation rust stain removal jobs. Oxalic acid is a great tool

I have had homeowners amazed and very thankful on how we can get the rust off their homes

Got to love how the Oxalic also brightens the concrete. We Xjet the Ox on at 4lbs to a 5 gallon bucket. The Ox is applied in just a few minutes

Jeff, great job. What was the dwell time for Ox?

On concrete it starts to work instantly and you learn to just shoot it on a little heavier in the darker areas. Dwell we leave it on and when its done its thing we will just give it a quick coat of water to dilute

The fence that took a few applications and then a quick rinse. On any vinyl if dark it takes a few applications and let it sit for just a few minutes and hit it again, so no real long dwell

We get quite a bit of this from irrigation systems from wells that arent deep

Jeff,

When I am back to work (last [?] operation last week from accident in July) I will post some before/after pics of a project I was working on. Shallow-well rust that has accumulated over the last 20 years. Oxalic barely made a dent. I was working on a combination of acids that make the concrete look new. I did a test area that looks like they replaced a few sections of sidewalk. All I'll say now is that a respirator is a must! P.S. It did NOT kill the grass along the edge. This house is in a high-end golf club neighborhood where green grass is more important than the rust.

I actually have several customers waiting for my "treatment" and they all have a "rust preventer" system installed. They are having crazy rust even when using the system with 3 and 4 gallons of Rid-O-Rust per 30 gal! I asked them (all know each other) if they had had their well water tested. "No", so I collected samples and sent them to the good folks at Rid-O-Rust and - at no charge - they sent me spreadsheets of the results. My customers were using the wrong chem! No one, not even their irrigation "specialists" had ever tested, only recommended more expensive systems.

i use "The works" toilet bowl cleaner to efis rust removal. its got hydrochloric(muratic) in it and if you shake it up real good its pretty thick and sticks good. oxalic is best for concrete.

Straight. I see no reason to spend the money for anything else when this does the job perfect. The cost of a 55lb bag is now $65 and 55lbs goes a longggggg way

Jeff,
I use oxalic acid on rust as well, works great! Where can i purchase a 55lb bag? I have been buying small containers of powder and need a larger quantity. We are in central NJ. let us know.
Thanks
Jim

Those are some classic JL rust removal pictures, I still remember when you were learning how to get them onto your computer.

Funny how in certain instances Oxalic won't cut the rust. I've called upon some hydroflouric to remove rust stains in the past. Honestly only tried it because of a household product containing it worked around the house.

John, hope you get back to 100% soon. How's that "wood magic" working out for you? I think I have found one of those roof monkeys you were telling me about.

You are a smart guy there Mr Orr, cool that you are solving the problem for the customers. Still having operations:pukey:. Hope it gets over with sooner than later for you

That would be something for sure.

Although with today's political correctness you'd have so much trouble deciding on who would belong...no asterisks.

It took me a bunch of trial efforts before I'd whole heartedly tell a customer I would guarantee rust stain removal. But once I got confident in my evaluation effort, I just say, "yep, not a problem"

We buy the kids the disposable cameras when they go on field trips...although I did see a digital camera for like $15....real photography is a lost art.
