How To Clean a Garage Floor: Concrete, Epoxy, etc.

A messy garage floor is never a good thing to see, especially when you use the space often. Keeping your garage floor clean helps you move around more easily and maintains an inviting space. While the occasional sweeping and mopping may suffice, there are specific steps you must follow to achieve a clean garage floor.

Let’s take a detailed look at how to effectively clean different garage floor types.

Why Should You Clean Your Garage Floor?

Most garages tend to be left uncleaned for several reasons. But if you’re not convinced enough to clean your garage floors, here are several benefits that may change your mind:

  • Health and Safety: A clean floor reduces trip hazards and reduces the spread of dirt and allergens into your home.
  • Improve Appearance: A clean garage floor instantly improves the look of the garage space and even motivates you to keep the entire garage tidy.
  • Increases Floor Lifespan: Regular cleaning prevents corrosive substances like oil and chemicals from damaging the flooring.
  • Enhance Usability: A clean floor makes your garage more functional for everyday use, whether parking cars or using the space for projects.
  • Prevention of Future Stains: Regular maintenance can eliminate stains and marks from setting in, making them easier to clean in the future.

Floor Cleaning Tools and Equipment You’ll Need

Before cleaning your garage floors, you’ll need several tools and equipment. Using these can make the cleaning process more efficient and safe.

Here are the things you need to get started on the floor cleaning job:

Tools 

Materials

Pressure washer or a hose with a strong spray nozzle – Ideal for loosening dirt and blasting away surface buildup

Stiff-bristle push broom or handheld scrub brush – Perfect for scrubbing stains and spreading cleaning agents across concrete

Squeegee – Helps clear standing water after rinsing to prevent puddles and speed up drying

Protective gloves and safety goggles – Important for protecting your skin and eyes from harsh cleaners

Shop vacuum or dustpan and brush – For removing dry debris before applying any liquids

Commercial-grade degreaser or concrete cleaner – Formulated to cut through oil, grime, and automotive fluids

Cat litter or oil-absorbing compound – Useful for soaking up fresh spills before scrubbing begins

Baking soda and dish soap – A gentle, homemade option for lighter messes or regular upkeep

Trisodium phosphate (TSP) – A powerful cleaner for deeply set stains or years of neglect

 

Pro tip: Always test harsh cleaners like TSP on a small, inconspicuous area first, especially on older or sealed concrete floors.

How to Clean a Garage Floor

Before you grab the brush and bucket, it helps to know the right way to tackle the job. Here’s a clear, step-by-step guide to help you clean your garage floor thoroughly and effectively:

Step 1: Remove Loose Dirt and Debris

Begin cleaning by sweeping the garage floor with a broom to eliminate loose dust and debris. This initial sweep removes surface dirt and prepares the floor for deeper cleaning. Make sure the entire floor is completely mark-free before proceeding to the next steps.

Step 2: Eliminate Oil and Grease Stains

For oil stains, apply cat litter or a commercial absorbent and let it sit overnight to absorb the grease. The next morning, sweep the dried litter, which has lifted much of the oil from the concrete surfaces. If grease stains remain, use a strong degreaser and allow it to penetrate the stain for 10-20 minutes before scrubbing with a stiff brush.

Step 3: Apply Cleaning Solutions

Mix a cleaning solution containing laundry detergent in a gallon of hot water for general cleaning or trisodium phosphate for tougher stains. Spread this solution evenly across the entire floor, covering every section. Allow the mixture to settle for 5-7 minutes to break down dirt and grime.

Step 4: Scrub With a Brush

Scrub the whole garage floor with a stiff brush or a push broom, focusing on stubborn stains and dislodged dirt. The brush’s physical action helps to clean the concrete’s pores deeply. Continue to scrub until you notice the dirt lifting from the floor.

Step 5: Rinse the Floor

Use a pressure washer or hose to rinse the floor thoroughly. This step washes away all the loose debris and cleaning products, leaving your garage floor clean and free from slippery residues. Make sure to remove all dirty water during this process.

Step 6: Dry the Floor

After rinsing, allow the entire floor to air dry or accelerate the drying with a squeegee to remove excess water. It’s important that the floor is completely dry before moving items back into the garage to prevent water damage or slipping hazards.

Specific Methods to Clean Epoxy and Concrete Floors

You can find various types of garage floors that have distinct properties. While following the general steps is enough, there are certain ways to clean them without damaging the surface.

Here are different flooring types and their unique cleaning processes:

How to Clean an Epoxy Garage Floor

  • Removing loose dust and debris with a broom or shop vac.
  • Combine soap and warm water, and dip the mop into the mixture.
  • Ensure all soap is rinsed with clean water to prevent a slippery residue.
  • Dry with a soft towel or leave the floor to air dry completely.
  • Inspect the floor and repeat cleaning if any tough stains persist.

How to Clean a Concrete Garage Floor

  • Start by sweeping off all loose dirt with a stiff broom.
  • Apply a commercial concrete cleaning solution or make a homemade mix using baking soda and hot water.
  • Scrub vigorously with a bristled scrub brush, paying attention to stained areas.
  • Rinse the floor thoroughly with a hose to make certain that no cleaner remains.
  • Use a squeegee or air-dry the floor to remove wet spots.

How to Clean Rubber Garage Floors

  • Sweep the floor thoroughly with a broom to eliminate dust and loose debris.
  • Combine mild detergent with lukewarm water in a bucket, avoiding harsh chemicals that may damage rubber.
  • Dip a soft-bristle brush or mop into the soapy solution and scrub the floor in small sections.
  • Rinse the floor with a mop or a damp towel to remove soap residue.
  • Wipe up excess water with a dry towel or a wet/dry vacuum to accelerate the drying process.

When Is Garage Floor Cleaning Necessary?

Maintaining a clean garage floor is an important part of home maintenance but some moments call for extra attention. Here are a few key times when a deep clean really makes a difference:

  • Spring Cleaning: After winter, cleaning removes salt and road grime that can erode the garage floor.
  • After Major Spills: Cleaning immediately after oil spills or chemical leaks prevents extensive damage and stains.
  • Biannual Deep Cleans: A thorough cleaning every six months preserves the condition and safety of the floor.
  • Before Hosting Events: If you use your garage as a functional space for gatherings, a clean floor is essential for a good impression.
  • Post-Construction: Any construction work can leave dust and debris that should be cleaned at once.

FAQs About Cleaning Garage Floors

What is the best way to clean a concrete garage floor?

For optimal concrete garage floor cleaning results, we recommend using a combination of commercial concrete cleaners and mechanical action with a bristled broom. This method effectively removes persistent oil, rust, and general grime. Strictly follow product label directions and give the cleaning solution enough time to break down the stains before scrubbing.

What is the best thing to clean your garage with?

The ideal cleaning solution depends on your garage’s flooring type. For concrete floors, specialized concrete cleaners provide the best results, particularly when coupled with vigorous scrubbing using a bristled scrub brush. For epoxy-coated or lightly soiled floors, a simple combination of mild laundry detergent and warm water usually maintains a clean and shiny surface.

Should you mop your garage?

Yes, especially if you have an epoxy-coated floor or one that’s mostly smooth. Mopping helps keep the surface looking clean and can extend the life of any protective coating. Just make sure to use a mild cleaner and fresh water so you don’t leave behind any film or residue.

Can I pressure wash my garage floor?

Yes, pressure washing is a great way to deep-clean concrete garage floors, especially if there’s built-up grime or oil stains. Sweep away loose dirt first, and use a pressure setting that’s strong enough to clean but not so high that it damages the surface.

CASE STUDIES

ANDERSON MILL GARAGE CONVERSION

ABOUT THE PROJECT:


When Olivia booked her free consultation, her garage was in tremendous need of immediate intervention. The plumbing didn’t work, the air conditioning had failed, there were fire hazards with the electrical and her garage door opener was connected to a disco light.

A single parent of two pre-teens and tech business leader, she wanted to create a space that served several purposes for her family: provide a clean, quiet office where she could be productive, create a maker’s space for the kids to do arts & crafts and LEGO, revamp the gym area and create a “performance” area where her kids could play music and put on plays.

With almost 900 sq ft to work with, we had a great footprint to make it all happen. But first, there was a lot of work to be done. The ground water pit had to be filled with concrete, the electrical had to be redone to facilitate new lighting and wall outlets, the plumbing needed to be brought up to code, the cabinets needed to be removed, her new office furniture needed to be designed and furnished and her gym needed some upgrades.

Watch the full video of this project here.

Over the course of several weeks, we had new heat pumps installed, the water heater replaced, the electrical redone, the garage door and opener swapped out, the concrete floor coated, a new cabinet system and slatwall installed, a dog bath delivered, amongst other work.

The result is a beautfiul space the family now enjoys together with friends and family. They host parties, create artwork and Olivia can be productive when working from home. When compared to buying a home 900 sq. ft. bigger in her area, although she invested just over $100,000 in this project, she saved over 56%! Garage conversions like these are cost-effective ways of adding livable space while preserving childhood friendships by remaining in the same school district, adding value to your home and avoiding the costs and hassles of moving.
