Good morning,
we have a big problem.
We have some rust stains on our patio slabs, which are made of simple concrete pavers.
How and with what can we remove the rust stains?
Can you recommend a cleaner or a good household remedy?
The rust stains were caused by an iron-containing lawn fertilizer that spilled onto the patio, and we didn’t clean it up or didn’t notice it.
How would you proceed?

We have beige concrete pavers that are supposedly coated or sealed. That's why using a pressure washer was initially discouraged.
At first, the rain did wash away some stains, but not all of them.
For example, we once temporarily stored oak wood on the terrace, which unfortunately left tannin stains. We managed to reduce them somewhat, but never got rid of them completely.
I also ended up with rust stains after placing the kids’ gates on the terrace while mowing the lawn.
Unfortunately, water had collected inside the pipes and then spilled onto the terrace. If I remember correctly, we also used rust remover.
Since we installed a roof covering, the protective effect of the stone coating has completely worn off. For the first few years, I tried cleaning with a garden hose and a broom, struggling without much success. Now I use a pressure washer with a rotating surface cleaner once a year and am very satisfied. The terrace almost looks like new afterward.
For grease splatters and drips from the grill, we regularly use Bref Power. That works quite well for removal.

The problem with the pressure washer is that it cleans out the joints again.
Does anyone know of a cleaning agent that we can work in with a brush and rinse off with a garden hose, which can remove as many stains as possible?

The driveway could also use some maintenance after more than 10 years, but we have eco-friendly paving stones there with wide joints filled with fine gravel. When all the small stones are washed out along with moss, soil, and plant debris, you can’t simply sweep them back in—you have to redo it completely.
