The Fastest Way to Clean Rust Stains from Concrete
In order to remove rust stains from concrete fast, you’re going to need the following tools:
- a pail
- a rust remover product
- a brush
- a stick or a drill to mix the material
The first thing you need to do is add a gallon of water to a five-gallon pail and then add a complete container of rust remover. The ratio is 1 gallon of water to 1 gallon of rust remover, unless indicated otherwise on the label.
After that’s done, use a stick if you want to manually mix it or you can also use a drill with a paddle. The goal here is to remove all the white clumps in the material.
Once that’s accomplished, regardless of your chosen method, you will be ready to apply the product.
Take the brush, apply it heavily, and put a nice rich coat on top of the rust. You don’t need to scrub, you just need to make sure that all the orange stains, light or dark, are covered with the material heavily.
All you need to do is apply enough material to the whole stain and then leave it alone. Some stains disappear almost immediately as you’re applying the product while some stains take a little longer. Usually, it will take between two to two twenty minutes to get all the rusting off.
The key thing is to not allow the product to dry, so the thicker the better. Rust remover works pretty fast, so be ready to remove it as soon as you see all the rust go away.
The rust remover has a jelly-like form and it doesn’t run, so you can work on inclined surfaces and not have the problem of running all over the place.
For smaller rust stains, you can also apply the product with a small paint brush.
When all rust stains are gone, rinse immediately with a garden hose or a pressure washer.
If you leave the product there for a very prolonged time, like four or five hours, it may leave a white stain.
