Staring down at your unsealed concrete floors, you might be entranced by their raw, industrial charm. They can be a beautiful addition to a modern home or workspace, but their aesthetic appeal is a double-edged sword. But knowing how to clean unsealed concrete floors indoors is another matter. 

Without the protective layer that comes with sealing, these floors are a magnet for dirt, grease, and stubborn stains that can seep into the porous surface. Unlike their sealed counterparts, unsealed concrete floors require a meticulous approach to cleaning to maintain their rustic allure and long-term durability. 

Ignore them, and you’ll find that they quickly lose their luster, falling victim to an accumulation of grime that’s unsightly and potentially damaging over time.

In the following article, we will delve into effectively cleaning unsealed concrete floors indoors. You’ll find tips and tricks for both regular maintenance and deep-cleaning tasks. 

We’ll also discuss how to handle different types of stains and spills so you’re prepared for anything your floors might face. Let’s roll up our sleeves and dive into unsealed concrete care—because even the most unforgiving surfaces deserve a little TLC.

The Nature of Unsealed Concrete

Concrete has many tiny pores and crevices that act like sponges to absorb liquids. This porous quality has some advantages but makes cleaning and decorating indoor floors difficult. Coffee or paint can stain unsealed surfaces, causing long-term damage.

These pores are sealed with a sealer or coating to prevent moisture, stains, and wear. This makes sealed concrete simple to clean; most spills wipe away, and routine cleaning is straightforward. Untreated concrete absorbs spills and dirt more quickly without sealer. If not addressed, oils, acids, and other substances can penetrate porous concrete and leave permanent stains.

The takeaway is that sealed and unsealed concrete floors require different types of maintenance. Unsealed floors require more maintenance than sealed floors, but they can be cleaned with sweeping and mopping. Unsealed concrete floors require more upkeep for a rustic look.

Why Indoor Concrete Floors Get Dirty

Concrete floors are not just a canvas for your interior design ambitions but also a daily life record. From the tread of your shoes to the paw prints of your pets, many factors contribute to the wear and tear of your indoor concrete floors.

  1. Spills: Spills are unavoidable, such as a spilled glass of red wine at a dinner party or an oil splatter in the garage. Spills on unsealed concrete floors can seep in and leave stains if not cleaned immediately because concrete is porous.
  2. Foot Traffic: Foot traffic on floors collects dirt and grime. Our shoes can bring mud and chewing gum, which can become embedded in the unsealed surface.
  3. Dust: Dust can be produced and attracted by unfinished or unsealed concrete floors. If not swept or vacuumed regularly, this can create a dusty layer that dulls the appearance and attracts other stains.
  4. Pets: Furry pets in the house add to the difficulty. If pet dander, fur, and ‘accidents’ are not cleaned immediately, they can leave permanent marks.

Step-by-Step Cleaning Process

Caring for your unsealed concrete floors doesn’t have to be a never-ending chore. With the right tools and a well-considered cleaning regimen, you can keep them looking their best. Here’s a breakdown of the essentials:

Protective Gloves

Steps for Cleaning:

  1. Remove Debris: Start sweeping or vacuuming the floor to remove any loose dirt and dust.
  2. Mix Your Cleaning Solution: Prepare your cleaning solution in a bucket according to the instructions on your chosen product.
  3. Pre-treat Stains: Pre-treat any stubborn stains by applying a small amount of undiluted cleaner directly onto the stain. Use your stiff-bristle brush to scrub.
  4. Mop the Floor: Dip your mop into the cleaning solution and wring it out well. Mop the floor, working in small sections. Make sure to rinse your mop frequently.
  5. Rinse: Empty the bucket and fill it with clean water. Rinse the mop and go over the floor once more to remove any remaining cleaning solution.
  6. Dry the Floor: Use dry towels to soak up any remaining moisture. Removing all excess water is crucial to prevent it from seeping into the porous surface.

Preliminary Cleaning

Remove any loose debris from unsealed concrete floors before deep cleaning. A broom with soft bristles or a ‘hard floor’ vacuum should suffice. Why is this step so important? Because grit and small particles from mopping can scratch and damage your floor. 

Before cleaning, you should also pre-treat any stubborn spots or stains. Ignoring them and mopping may spread or ingrain the stains in the porous surface, making removal more difficult.

Stain Removal

Not all stains are the same. Oil, grease, and ink spills are more difficult to clean up than water-based spills. To select the best cleaning solution, you must first identify the type of stain. Oil and grease stains necessitate the use of specialized concrete cleaners. 

Ink stains may be removed with rubbing alcohol. Always begin with gentle cleaning and work your way up. Steel wool and acidic substances can permanently damage concrete. Test a small area before treating a visible stain.

Deep Cleaning

It is best to deep clean unsealed concrete floors with pH-neutral cleaners. Because unfinished concrete is porous, it is vulnerable to acidic and alkaline substances that can discolor or damage it. According to the manufacturer’s instructions, begin by diluting your pH-neutral cleaning solution in a bucket. 

Begin in one corner and work across the floor in sections, careful not to let the solution sit. Use a stiff-bristle brush to scrub dirty floors. After cleaning, the floor must be rinsed with clean water to remove any cleaning solution. Finally, use clean towels to dry the floor to prevent concrete moisture absorption.

Your cleaning solution can make a significant difference in maintaining unsealed concrete floors. A good cleaner removes dirt and grime while also protecting porous surfaces. 

The best unsealed concrete cleaning agents will be discussed in this section. Cleaning everyday grime or stubborn stains with the right cleaner can make all the difference.

pH-Neutral Cleaners

Cleaning unsealed concrete floors with pH-neutral cleaners is the safest option. These solutions protect your porous concrete floor because they are neither acidic nor alkaline. Commercial options include Simple Green Oxy Solve and Krud Kutter’s Concrete Cleaner. 

A natural option is a DIY solution of equal water and white vinegar. Even if a cleaner claims to be pH-neutral, test it on a small, inconspicuous area first.

Mild Detergents

A mild dishwashing soap or laundry detergent is another gentle cleaner for unsealed concrete floors. A cleaning solution is made from a bucket of warm water and a few drops of mild detergent. Stir until suds appear. Using this solution, mop the floor, paying special attention to grimy spots. 

After covering the surface, rinse it with clean water to remove any soap residue. Mild detergents like pH-neutral cleaners will not harm unsealed concrete, but a patch test is recommended first.

Specialized Concrete Cleaners

Grease, oil, and ink stains may require specialized concrete cleaners. These items are intended to remove stubborn stains from porous surfaces. CAF Outdoor Cleaning EXIMO and Terminator-HSD Concrete Cleaners are built for tough jobs. 

These are available at hardware and cleaning supply stores. Because concentrated formulas must be diluted before use, follow the packaging instructions. Always perform a spot test to ensure it will not damage or discolor your floor.

What To Avoid When Cleaning Unsealed Concrete Floors

While the right cleaning methods can work wonders on unsealed concrete floors, the wrong ones can create irreversible damage. Since these floors lack a protective sealant, they are particularly vulnerable to harsh chemicals, abrasive tools, and incorrect cleaning techniques. 

In this section, we’ll steer you clear of common pitfalls in the cleaning process, aiming to preserve both the aesthetic and structural integrity of your unsealed concrete floors.

Acidic Cleaners

On unsealed concrete floors, acidic cleaners should not be used. Concrete can be etched and eroded by low-PH cleaners such as vinegar, lemon juice, and others. 

This can cause visual and structural damage to your floors, making them more susceptible to staining and deterioration. Use pH-neutral or mild concrete detergents to extend the life and beauty of your flooring.

Harsh Chemicals

Unsealed concrete floors can be damaged by bleach and ammonia. Harsh chemicals have the potential to discolor and weaken concrete. 

Corrosion can weaken the porous surface, making it more prone to staining and damage. Read labels and choose concrete floor cleaners or mild, natural alternatives for safer cleaning.

Excessive Water

Unsealed concrete is vulnerable to water damage due to excessive water porosity. When cleaning, using too much water can be disastrous. Water can penetrate deep into the concrete pores, causing structural damage or mold growth. 

To avoid this, wring out your mop before using it on the floor and dry it with towels or a wet vacuum afterward. To avoid long-term problems, avoid saturating the floor.

Prevention and Maintenance Tips

Proactively caring for unsealed concrete floors can help to extend their life and improve their appearance. Cleaning regularly is important, but preventing stains and damage is even more critical. These tips will help you keep your unsealed concrete floors in good condition:

  • Using Floor Mats at Entrances – Dirt, mud, and moisture can all be captured by entrance floor mats before they reach your unsealed concrete floor. This simple step can reduce floor grime significantly, making regular cleaning easier.
  • Cleaning Up Spills Immediately – Because of its porous nature, unsealed concrete absorbs spills quickly, making cleanup more difficult. The spills should be cleaned up right away. Immediately absorb the liquid with a cloth or paper towel to avoid staining, and wipe it down with a suitable cleaner.
  • Avoiding Harsh Chemicals – Bleach and ammonia, in particular, harm unsealed concrete. Always use pH-neutral or mild concrete floor detergents. This effectively cleans and protects floors.
  • Regularly Inspecting the Floor for Signs of Wear or Damage – Unsealed concrete can be damaged and worn in high-traffic areas. Inspections regularly can detect minor problems before they become major ones. Repair or spot-cleaning may be required for chipping, cracking, or staining.

Concrete floor sealing has advantages and disadvantages that homeowners should consider. Concrete floors that have been sealed are resistant to stains, moisture, and wear. Sealing makes the surface less porous, making cleaning and maintenance easier. This may extend the life of your concrete floor and reduce the need for deep cleaning.

However, there are some disadvantages to sealing. Sealing can be costly if professional installation and high-quality sealant are used. Sealed floors must also be resealed regularly to maintain their protective properties, which takes time and money.

Concrete floor sealing is optional but may provide additional protection for some homeowners. Sealing may be beneficial if you constantly fight stains and wear or want to reduce the need for deep cleaning.
