Rust stain removal in St. Petersburg
Orange sprinkler stains are chemistry, not dirt. More pressure just wears the concrete.
Sound familiar?
Is this your house?
Orange fans by the sprinklers
Iron in well water, left behind every time it dries.
Rust under a pot or a grill
Metal left on concrete stains it quickly.
Lighter patches with orange still in them
Somebody tried pressure. It wore the surface and left the stain.

On the job
Where it usually is
Along the drive where the sprinkler reaches, and under anything metal left sitting on the concrete.
- Tested on a spot first
- Treated, not blasted
- The sprinkler head pointed out
How we do it
Rust removal, in order
Test spot
A small patch first, somewhere out of sight.
Treatment on
A rust remover applied and given time to work.
Neutralized and rinsed
So the concrete isn’t left etched.
The cause
We point at the sprinkler head or the source.
What it costs
What decides the price
Every job is priced on a written estimate after somebody has looked at the surfaces. These are the things that move the number.
How many stains
A few spots or a whole wall of sprinkler fans.
How old they are
Heavy, old staining can take a second application.
The surface
Pavers and stucco need gentler products than concrete.
The details
For the people who want every step
Why pressure cannot win
Iron staining is in the pore of the concrete, not on it. Pressure removes concrete, not rust — you end up with a lighter patch of eroded surface and the stain still visible in it.
What actually works
Oxalic acid, given dwell time, then neutralized and rinsed. On heavy staining it takes more than one application, and we will tell you that up front rather than promising one visit.
Fixing the cause
If it is irrigation, the head is throwing onto the concrete and it will come back in a month. We will point at the head. Fixing it is somebody's job and it may as well be a cheap one.

What people ask us about this
Will the stains come back?
Only if the cause stays. Adjust the sprinkler head and they shouldn’t.
Can you remove rust from stucco?
Often, with a gentler product. We test first.
Is it safe for my grass?
We protect and rinse the turf around the treated area.
