The Secret to Cleaning a Concrete Floor Stain

April 5, 2019

Concrete used to be viewed as a durable but basic material that was only used outdoors or in places that did not see much foot traffic like basements and garages.

However, over the last couple of decades, concrete has become a more popular choice for interiors. You can now find countertops and floors all throughout contemporary houses made up of this material to give it that sleek sophisticated look.

If your property happens to be one that contains concrete floors, then you need to know how to properly take care of it to keep it looking its best for years to come. A large part of that is knowing how to clean the concrete floor when a spill happens.

Sooner or later, whether it is from you or one of your tenants, your concrete floor is going to get a stain.

Rather than trying to avoid one of the most common property maintenance issues, it is best to read through the rest of this article and find out exactly what to do when this happens.


The type of concrete matters!

Surprisingly, not all concrete floors are the same.

There are actually four main different types of concrete floor finishes that may be in your rental property.

Overall, they consist of unsealed, sealed, polished, and painted. Knowing which one you have and what the differences are is important to be able to clean your concrete floor stain as best as you can.

Treating unsealed concrete

Unsealed floors are the most basic of all concrete as it involves just laying out the concrete and letting it set. No additional treatment is done to it and therefore it still has its incredibly porous surface.

Treating sealed concrete

Sealed floors are concrete that is coated with a mixture of chemicals in order to fill in the surface pores and make it more resistant to stains.

Treating polished concrete

Polished floors are concrete that is permanently polished in order to give the floor a shiny appearance that mirrors granite or marble.

Treating painted concrete

Painted floors are concrete that is simply painted to become a certain color.

If the paint that you are using is latex or oil-based, then it will be much harder to get the color to be permanent or extremely durable. This is usually done on unsealed floors because floors that have already been sealed or polished will cause the paint to peel much faster.


How to clean unsealed concrete?

How you should go about cleaning your concrete floor stain also depends on the type of stain.

With any kind of food or drink stain, you will want to combine some dish soap with some water and apply it to the stained area. Then grab a nylon-bristled brush and thoroughly scrub the area.

Afterward, simply rinse off the area with water and the stain should hopefully be gone.

For grease stains, the process is a little more lengthy. You will need to grab some kitty litter or cornstarch and to cover the stain. Then simply leave it alone for three entire days.

While you are doing this, the material is absorbing up the grease so that you can simply vacuum it away once the three days are over.

If the concrete floor stain is caused by rust, then you will need to look at the significance of the stain to determine exactly what steps need to be taken.

For less serious light stains, you just need some distilled white vinegar to put on the stain and let sit for about half an hour. Then grab a nylon-bristled brush and begin scrubbing until the stain appears to be gone and you can rinse the area with water.

However, more serious dark stains will require you to go out and purchase a commercial rust remover to get the job done.


How to deal with sealed, polished, and painted concrete?

If you have anything other than unsealed concrete, then some additional precautions will need to be taken when cleaning your concrete floor.

For example, sealed concrete usually only requires that you mop the area with a mixture of dish soap and warm water in order to remove any stains. Just make sure that you stay away from any harsh cleaning chemicals that can affect the quality of the sealant.

Polished floors only require you to mop the area with a ph-neutral polished concrete cleaner which should be able to remove pretty much any stain.

Painted floors require you to be a little more careful with your cleaning methods. Any acidic cleaning chemicals could end up damaging the paint, so it is best to just mop the floor with an all-purpose cleaner and then rinse the area with water afterward.
