Remove rust stains from brick and cement to keep you home looking its best. Unsightly rust stains can ruin the appearance of your home. Rust stains can be tricky to remove if you use the wrong product on them. Here are some guidelines to make it easier to remove those stains.

Step 1 – Safety First

Put on rubber gloves or chemical proof work gloves to protect your hands and eye protection to protect against splashing chemicals. Be sure that your pets and children do not have access to the area.

Step 2 – Loosen the Rust

For a tough rust stain sand it with steel wool or sandpaper sweeping away the rust with a brush as you go.

Step 3 –Apply the Product

Apply a commercial rust remover according to the manufacturer’s directions, letting it sit on the rust stain from a few minutes up to a few hours, depending the product you are using.

Step 4 – Scrub the Area

After it has rested then take a stiff scrub brush and brush over the area. If it does not come off completely then apply more rust remover and let it sit again and brush it once more.

Step 5 – Rinse

Take a water hose with a nozzle and rinse the area to remove the rust. Be sure to clean it thoroughly so that the rust remover is completely rinses away. If your rust stains are more difficult to remove then try one of the following steps to get rid of them.

Step 6 – Attach Stubborn Stains

Pour boiling water over the stain, apply a rust removal powder. Let it stay on the stain for about 30 minutes. Scrub the area with a stiff non-metal brush and rinse it off.

Step 7 – Use Toilet Bowl Cleaner

A toilet bowl cleaner made of hydrochloric acid can help to get rid of stains. Pour it on the stain, let sit for a few minutes and rinse it away. This is not a good solution if in rinsing you would be getting the polluted rinse water on your grass or near any plants. It should only be used if the rinse water can be directed directly into a street sewer.

Step 8 – Use Cookware Cleaner

A cookware cleaner designed to remove rust from metal can be sprinkled on a rust stain and then its abrasive texture along with a scrub brush will help to remove rust stains from brick or cement.

Sometimes a rust stain isn’t rust at all but a red colored dirt or mold. You can try a spot of bleach on the spot. If it is mold and not rust it will turn white. Bleach does not work on rust and may make it worse so test a small area first.
