How to remove rust stains from a stone patio in 4 easy steps
Removing rust stains from your patio is both easy and affordable with Universeal’s Rust-Off non-acid formula. By following the manufacturer’s guidelines, your patio will look as good as new after you’re done with it.
Here’s how you do it.
What you will need:
Before you start, make sure you have the following applicators to hand:
This formula is undiluted, so you just need to apply it directly to the affected area.
You must complete a small area to understand exactly how the product works and reacts on the surface of your particular stone.
1: Apply the Rust-Off product
Ensure the area you’re working with is completely dry. Dry, meaning uncontaminated with no previous cleaners on the area, and not affected by any surface water or possible moisture. This will allow the product to target the rust more effectively.
Apply the Rust-Off formula to the stain, as generous as you need to be, to ensure all areas are covered.
The best way to apply, is either pouring the formula straight on or by using a paintbrush. Because it’s non-acidic, you can even distribute amounts into a bucket/measuring jug and apply it as you go. A paintbrush is also ideal for those hard-to-get areas.
For larger areas, you can pour the product directly on the stain and distribute using a deck brush or broom.
If you feel a stain is particularly stubborn, work the product in more thoroughly after it has been applied.
This can be done with a sponge, squeegee or even an old toothbrush.
Soon after it is applied, you will notice a reaction taking place, which turns the solution a dark purple, this dark purple reaction will only occur if the stain is iron oxide rust. If this doesn’t happen within 1-2 minutes then this will confirm the stain is definitely not rust and will need to be reassessed and need for an alternative cleaning solution.
2: Let the Rust-Off settle for 5 to 10 minutes, Do not leave for an extended period of time
Allow the product to work for approximately 5 minutes, once all of the orange rust stain has turned a dark purple colour then you can start to slowly rinse with clean water.
It is recommended you do not exceed 10 minutes.
3: Rinse the stone patio off with a hose
The best and easiest method to rinse off, is by using a hose. Another source of clean water is also fine.
Simply rinse away the product and watch as the results come to light. For stubborn areas, it may be necessary for a second application. Allow the product sufficient drying time for a final finish. Weather permitting, this shouldn’t take too long, depending on the type of stone you have used.
4: Repeat the process if some rust stains are harder to shift
If the rust stain or purple staining is still slightly present, repeat steps 1 to 3. For stubborn areas, no more than 3 applications should be required.
For whatever reason more than 3 applications are needed, it should be noted that possible discolouration may occur. For more technical support contact our technical helpline 01300 345898 ext2
