How to Clean Concrete Floors Indoors: The Complete Guide
Cleaning concrete floors indoors is one of those jobs that looks simple until you try it for real. Concrete is porous, so it grabs everything - oil, grease, tire marks, dust that gets ground into the surface from feet and forklift traffic.
But you can't hose it down inside a building. You need a real plan if you’re cleaning indoor concrete floors in any commercial setting. Otherwise, they’ll just get worse every month. Well, you’ve come to the right place! We’re going to show you how to clean concrete floors indoors.
The short answer is you just need to upgrade to a commercial floor scrubber. It handles most messes you’ll encounter and can work on just about any type of concrete - finished, sealed, polished, you name it. We stock the best machines from the top brands the industry has to offer. Get the best floor scrubber for concrete, and learn more about concrete floor cleaning below!
What is the Best Way to Clean Commercial Floors Indoors?
Machine beats manual every time. Think about it. Brooms kick dust into the air. Mops push dirty water around without pulling contaminants out of the pores. Cleaning concrete floors by hand in a big space wastes labor and the results end up mediocre at best.
So, how do you clean concrete floors at scale? Two steps:
- Dry first
- Wet second
A commercial floor sweeper collects dust, grit, and loose debris without kicking particles around and simply spreading the mess. Then a floor scrubber lays down a cleaning solution, brushes it into the concrete, and pulls the dirty water back up with a squeegee and vacuum system.
The floor is left dry behind the machine, and it looks impeccable. The best part? Your operators aren’t exhausted, and the whole process takes a sliver of what it used to. A floor sweeper scrubber handles both tasks at the exact same time, saving even more man hours.
Machines are a must, but the chemical matters, too. You’ll use a neutral cleaner for routine dust and a degreaser for oil, hydraulic fluid, or anything petroleum-based. Cleaning concrete floors with the wrong chemistry not only leads to subpar results, but could damage them.
How to Clean Indoor Concrete Floors: Cleaning Different Types of Concrete Floors
You may already know that not all concrete is to be treated the same. Figuring out how to clean indoor concrete floors depends on what finish you're working with:
- Raw
- Polished
- Sealed
- Stained
Each responds differently to products and equipment. Get it wrong, and cleaning indoor concrete floors does more harm than good. We’re here to help you avoid that.
How to Clean Unfinished Concrete Floors
No sealer or coating makes raw concrete the hardest type to keep clean because every spill soaks straight in. Oil becomes permanent within hours. So, how do you clean concrete floors with no protection on them?
Sweep daily to catch grit before it grinds in. Scrub with a degreaser when you see buildup on the surface. Cleaning unfinished concrete floors that are unfinished lets you be aggressive on the chemistry side of things.
How to Clean Polished Concrete Floors
Polished concrete resists staining, which is great. Liquids bead instead of soaking in. This type of concrete is popular in retail spaces, showrooms, and lobbies.
But it shows everything - every scuff, footprint, and water spot. The stakes are a little higher as far as keeping up appearances. You end up cleaning concrete floors more often.
You also need to be a little more careful as far as what you use. Neutral pH cleaner only. Acidic or alkaline products dull the polish. Make sure you’re scrubbing with soft pads. You need to set your expectations for what cleaning can accomplish as well. The floor needs re-polishing if its shine fades - not a stronger chemical.
You’ll rarely need more than a walk-behind scrubber and neutral solution for cleaning indoor concrete floors with a polished surface. We walk people through how to clean indoor concrete floors with a polish all the time. Just get in touch for a recommendation on the right machine, pads, and solution.
How to Clean Stained/Sealed Concrete Floors
A sealer puts a barrier between the concrete and whatever lands on it. You have a little more time to react since spills sit on top instead of soaking in. How to clean concrete floors indoors is a lot easier when there's a seal in place.
Just follow the same sweep-then-scrub routine. Keep an eye on that sealer, though. Traffic wears through it - and you're back to raw concrete problems once it’s gone altogether. Recoat before that happens.
We also suggest you test new products in a hidden spot if you’re cleaning decorative stained concrete in restaurants or retail. Some chemicals discolor the stain even through the sealer. So, how do you clean concrete floors with a decorative finish? Carefully!
More Tips on Maintaining Concrete Floors
Cleaning indoor concrete floors is half the battle. Prevention is just as important, if not more so.
Put heavy-duty mats at every entrance to catch grit off boots and wheels before it hits the floor. That grit causes micro-scratches under traffic, and those scratches trap dirt. Cleaning concrete floors takes way less effort when you have less to clean and fewer places for messes to hide.
Spills get handled the moment they happen - not end of shift. 20 minutes can be the difference between a clean floor and a permanent stain on unsealed concrete.
How do you clean concrete floors on a consistent schedule? Assign it. Put names on the board. Accountability is the only thing that keeps your routine dialed in. Sweep daily. Scrub weekly or more based on traffic. Reseal on the cycle your floor manufacturer recommends.
