How To Remove Paint, Oil, Rust Stains From Concrete Floor

Remove Paint Stains From Concrete

Removing paint stains from concrete can be difficult and tiresome. But with the right product and perseverance you can do it.

  • For small spots:

    o The first step to clean the surrounding areas. Remove all other dirt and debris. Try to remove paint by scraping or mopping in case there is any loose paint.
    o Depending on the type of paint that has been spilt, use a paint stripper to clean the area. If you’re not sure about what kind of paint was spilled then go for a stripper designed to work on oil-based paint. Each brand has a different time period required for it to work, which is mentioned on the label. Depending on the time mentioned on the label, let the stripper work.
    o Once the time specified is over, scrub the area clean with a brush, scarper or pressure washer.
    o Repeat the above mentioned process till the paint is completely gone.
    o Once the paint is gone, clean the area with plain water to remove all signs of the paint stripper.

  • For Tougher Spots:

    o You will need a paint stripper, an absorbent material such as clay and a brush and scouring powder for cleaning up after.
    o To begin with, in a tub or container, create a mixture of the absorbent material and the paint stripper depending on the thickness of the stripper.
    o Apply a generous layer of the mixture of the absorbent material and the stripper on to the stain. Depending on the stain, it might take anywhere between half an hour to several hours for the mixture to work. While you’re waiting for it work, keep adding paint thinner to it every now and then.
    o Scrape the mixture off with a scraper or a plastic brush and see if the stain has gone. The paint thinner will mostly work and allow you to scrape off a major chunk of the paint.
    o In case there is still paint left, repeat the entire process.
    o Scrub the area again

Removing Rust Stains From Concrete Floor

Rust is ugly and makes any concrete surface look shabby. It gives off the impression that things are not taken care of. There are many ways of dealing with rust starting from commercial rust removers to simple home remedies.

  1. Vinegar, whether white or apple cider is a god sent when you need to clean something. Usable on practically anything, rust is no exception. Just spritz or pour it on to the area with the rust. Let it remain so for a while and rinse afterwards. If the stain still remains then just repeat till the stain is gone.
  2. Lemon juice is another very good rust cleaning agent, especially if the area you need to clean is a small area. The concentrated citric acid in the lemon acts perfectly for removing the stain. All you need to do is pour it onto the stain and let it stay for ten to fifteen minutes after which you can just clean it up with a brush.
  3. The other alternatives are commercial stain removers. While using these, take necessary precautions such as wearing gloves and protecting your eyes and other long sleeved clothing to protect your skin. Apply the cleaner on to the surface and let it sit for a while after which you can brush off the area.

Removing Oil & Grease Stains From Concrete Floor

Sometimes cars or bikes leak oil when they’re not in use and end up creating spots of grease which are untidy looking to say the least. Fortunately there are many options available for ridding yourself of these stains.

  1. What you need is ground cat litter, cans of a cola beverage, a brush to clean with, laundry detergent, liquid chlorine bleach and a bucket to mix.
    • Also use gloves for protection and running water.
    • Cover the stain with ground cat litter.
    • Remove it after a while and dispose it carefully.
    • Cover the oily area with cola beverage now.
    • Work on it with the cleaning brush and keep the area damp.
    • Let it stay for about 30 minutes till the fizz is gone.
    • Rinse it off with the running water which should reveal a grey stain.
    • This can be cleaned with a solution made using one cup each of liquid chlorine bleach, ammonia free laundry detergent and a gallon of boiling water.
  2. The second technique is to use Muriatic acid. Mix one part muriatic acid with nine parts water. Add the acid to the water, not vice versa. Pour the solution onto the stain and scrub with a broom. Once the solution stops fizzing, clean the area out with clean water. Repeat if necessary.
