All types of pavers, whether they are made from concrete, brick, or stone, can suffer from rust stains especially if you have metal chairs and furniture on your patio. Prevention is the best way to protect your pavers from rust stains. This means you have to properly paint metal furniture before you place them on the patio. However, there are instances that rust stains will still appear on the patio paver as the paint coating of the patio furniture disintegrates. So here are some basic tips on how you can remove rust stains from patio paver.
Using Pure Lemon Extract
If the rust stains on your patio paversare not severe, then you can grab a fresh lemon and use it as a natural patio paver cleaner. Do not use artificial or concentrated lemon juice as cleaning agent because it will not remove the stains on the paver.
First, you have to cut the lemon in half and squeeze its juices on the affected areas. Allow the natural acid of the lemon juice to react with the rust stains. Let it stand for at least 15 to 20 minutes but do not allow the lemon juice to dry. After 15 minutes, grab an old toothbrush and start brushing away the rust stains from the paving stones or bricks. This solution will restore your patio to its old beauty.
Fighting Rust Stains with Vinegar
If the rust stains on the patio paver are too severe and you are seeing large stained areas on the pavers, then you have to use a stronger cleaning agent. Your best bet is to use pure or distilled white vinegar which you can easily buy from a local grocery.
The first thing that you should do is to remove sand, soil and other dirt on the affected paving stones. Pour the vinegar over the stained area and allow it to react and dissolve the rust. Just wait for 20 minutes before you brush off the rust stains. You may have to use a large brush with stronger bristles in order to complete eliminate the rust stains from the stones or bricks.
In case lemon extracts and vinegar failed to do the trick, then you are faced with tough rust stains that have already seeped in to the outer coating of the pavers. In such cases, you can use special chemical cleaning agents for patio paver. You can ask the company who installed the pavers if it has the right cleaning agent against rust stains.
However, you can easily use oxalic acid to remove rust stains on your patio. You have to remember that oxalic acid is a toxic agent so you should handle it properly. You have to follow the instructions on the packaging of the oxalic acid in order to protect yourself and the vegetation around your patio.

One scoop of oxalic acid in a bucketful of water should be enough to remove tough rust stains. Just pour the solution over the affected areas and let it stand for 10 to 15 minutes. After that, you can now start brushing off the rust stains using a plastic brush.
