How Do You Get Stains Out of Concrete?

Concrete is an incredibly versatile and durable material, but it can break down over time. One of the most common issues with older concrete is stains. Luckily, it’s really quite easy to fix concrete stains. Today, we’re going to go over some of the most effective methods for removing a stain from concrete. 


The first step towards getting rid of any concrete stain is identifying what type of stain you’re faced with. For example, is this an oil stain, a paint stain or an ink stain? Each type of stain will need a different method to safely get it off the concrete. 


Basic Stain

A simple discoloration on concrete is actually very simple to fix. Just mix 1 cup of ammonia with 1 gallon of water. This diluted mix will easily remove any basic stains, without damaging the surrounding concrete. Rember, it is crucial to dilute the ammonia or you will risk eating away at the healthy concrete. 


Oil Stain

Oil stains are incredibly common, particularly in garages. Whether you’re working on your vehicle, or some motor oil just happens to leak out it’s incredibly common for an oil stain to appear on a garage floor. Luckily, it’s possible to get these out. 


The first step is to grab some paper towels and mop up the excess liquid. After that, take an old nylon scrub brush and get to work with some soap and water. If you find yourself facing a particularly stubborn stain, try covering the stain with a generous amount of WD-40, then wipe up the excess liquid. 


Red Wine Stain

Red wine stains are some of the most feared, but the truth is they happen quite regularly. If you have a concrete patio you’re almost sure to experience a red wine stain at some point. Unlike with white clothing, it is possible to get a red wine stain out of concrete. 


To start, mix a few drops of tea tree oil and glycerin with several quarts of water. Take that mixture and scrub away at the red wine stain, then leave it to sit for a half an hour. Repeat these steps until the stain has been completely removed. 


Mildew Stain

Mildew stains are not just unsightly, but they can become quite dangerous. Oftentimes some direct sunlight and ventilation will cause mildew to clear up on its own. However, if that mildew just won’t go away, there are some more drastic measures that can be taken. 


Mix together a quart of chlorine bleach with three quarts of water and a third a cup of powdered laundry detergent. Take a brush and apply a thin layer of the mixture to the mildew. Let that sit until the mildew turns white, but don’t let it dry! Then wipe off the mixture and repeat as needed. 


Concrete stains are not just common, they’re borderline inevitable if you have concrete flooring somewhere. Thankfully, with a little elbow grease and know-how it’s fairly simple to remove all types of stains from concrete. Hopefully this article helps you get your concrete looking like new again in no time at all.
