Removing Rust Stains from Cement Patio

Over the winter, some metal patio furniture left rust stains on our patio. We've tried scrubbing it, but there are still some marks on the concrete. What's the best way to remove the rust stains without putting the plants that surround the patio or our children and pets at risk?

Use Pressure Washer to Remove Rust Stains

The pressure washer is our outdoor go to appliance for cleaning. It has been used to remove everything from paint drops to rust on our concrete. It really uses very little water for the cleaning it provides. Most of the time we use just plain water, but our pressure washer has a reservoir for additional cleaning agents like soap or TSP.

Try CLR®

Use a product called CLR®. You can use it to remove calcium, lime, and rust stains. Just wet the area, sprinkle some on, scrub it with a brush, and let it sit for 10 minutes or so.

Safe and Effective at Removing Rust Stains

Try Naval Jelly that is available at most hardware stores. It's safe and will do the job.

Vinegar Is Good at Removing Rust Stains

Vinegar dissolves rust. Straight vinegar or a vinegar paste should help.

Worked for Tub. May Work for Patio.

I had an issue with rust stains on my tub from a can of shaving cream. I sprayed oven cleaner on the stain, let it sit for a few minutes, and wiped it up. This worked wonders with no harm to the surface of my tub. This should work on concrete as well. Plus, the spray should be able to penetrate the little grooves in the concrete.

This Did the Job at Removing Rust Stains!

I don't know if this will work on concrete, but give it a try. I just removed some rust stains from a carpet. I had nothing to lose and really didn't think it would work, but it did!

I made a paste of cream of tartar and a bit of water to a consistency similar to toothpaste. (Mine was a little thinner.) I spread it on the rust stain and let it sit overnight. I vacuumed it up and then rinsed with vinegar. For concrete, after the vinegar, I'd try just spraying with a hose.

Give Your Patio a Makeover

Why not use concrete stain and do the whole patio the same color? It's easier than trying to get that stain out and probably safer all around.

See Immediate Results

I have an ancient bottle of Whink® Rust Stain Remover. I poured a very small amount on rust stains on concrete, and they immediately disappeared. This product can also be used on rust stains on color-fast clothing, carpeting, and toilet bowls. It contains hydrofluoric acid, so it is poisonous.
