General Preparation Before Cleaning

Prior to getting into the actual cleaning, preparation is the aspect to helps make the work a process that is efficient and effective. Regardless of whether you are working with an epoxy-coated surface or raw cement, these universal steps are going to put you on a path to success.

Clear the Garage

Begin by clearing the garage floor of all the items. That includes vehicles, tools, shelves, bins for storage, and anything that can block the cleaning process. It is much easier to clean the garage floor surfaces when the place is wide open and has no clutter.

Sweep and Dust Thoroughly

Use a stiff-bristled push broom or heavy-duty shop vacuum to pick up loose dirt, dust, leaves and cobwebs, or other debris. This first brush gets the real washing working much better, so you are not scrubbing over dry messes or pushing grit around the place.

Gather Your Cleaning Supplies

Having the right tools and products on hand is essential. Depending on the floor type and level of grime, your kit might include:

• A garage floor cleaner (degreaser, detergent, or all-purpose solution)
• Stiff brushes or deck scrubbers
• Pressure washer or garden hose with high-pressure nozzle
• Mop and bucket
• Absorbents like kitty litter or baking soda for how to remove oil from the garage floor
• Protective gloves and safety goggles
• Wet/dry vacuum (optional)

General Garage Floor Cleaning Method

Regardless of the type of surface, be it cement, concrete, or epoxy, the general strategy to clean the areas within a garage floor is similar in many ways. A set of steps guarantees that your floors remain free from dust, grease, and accumulation. Here’s how it is done.

1. Pre-Treat Stains and Spills

Before applying any general garage floor cleaner, identify visible stains. For oil and grease spots, sprinkle absorbent materials like kitty litter or sawdust directly on the stain. Let it sit for a few hours to soak up the excess. This is the first step in how to remove oil from the garage floor, which helps prevent deep penetration into the surface.

For stubborn stains like rust or paint, use a commercial degreaser or a vinegar-baking soda paste. Apply it to the affected area, scrub gently with a stiff brush, and let it rest for 10–15 minutes before rinsing.

2. Apply a Garage Floor Cleaning Solution

Next, mix a high-quality garage floor cleaner or degreasing detergent in a bucket with warm water, according to the manufacturer’s instructions. Pour or spray the solution generously across the entire floor surface. For large garages, you can do this in sections to maintain control and consistency.

3. Scrub the Floor Thoroughly

Using a deck brush or stiff broom, use floor scrubber to scrub the floor in circular or linear motions. This helps loosen grime, salt buildup, and chemical residues. Scrubbing is a crucial step in how to clean a garage floor, especially when the surface hasn’t been cleaned in a long time.

If your garage has textured concrete, pay extra attention to grooves and rough patches where dirt can accumulate.

4. Rinse the Floor

Once the scrubbing is complete, rinse thoroughly using a garden hose or pressure washer (on a low-pressure setting if the floor is coated). This is also a practical part of how to clean concrete garage floors, as it removes both detergent and dislodged grime.

Be cautious around walls or storage units to avoid splashing dirt back onto clean areas.

5. Allow the Floor to Dry

Use a mop or wet/dry vacuum to remove excess water, especially in low-lying areas where puddles can form. Let the floor air-dry completely before returning items to the garage. If you’re dealing with an epoxy surface, this is especially important to prevent any clouding or surface damage.

6. Apply Sealant or Protective Coating

If your garage floor is concrete or cement, consider applying a sealant after drying. This step isn’t required every time, but doing it once every few years improves durability and stain resistance.

Step-by-Step: How To Clean a Garage Floor Using a Pressure Washer

Step 1: Clear the Garage

Begin by clearing all items in the garage — vehicles, tools, bins, and floor mats. With which you have full control over every corner of the floor, and sweep or vacuum any scattered debris, dust, or cobwebs.

Step 2: Pre-Treat Oil and Grease Stains

Spray your concrete degreaser around all stained areas. Wait about 10–15 minutes. For the most stubborn stains, scrub the area with a stiff brush to break up residue before rinsing. This is to make sure the cleaner is able to lift stains a little more with the pressure washer.

Step 3: Prepare the Pressure Washer

Put your garden hose in, and plug up the pressure washer (or if it’s gas-based, fuel up if preferred), attach a 15° or 25° nozzle, which works best on hardscapes such as concrete. Before you use the pressure, do a pressure test on a small, discreet area where the pressure is not too intense.

Step 4: Wash the Floor

Start pressure washing from the back of the garage to the door so all dirt is being pushed from back to inside out of the garage. Using gentle overlapping strokes, very lightly scratch each square inch. Keep from standing in the same location too long to avoid streak marks or etching the surface.

Step 5: Final Rinse and Dry

Now spray the whole floor, go over it again with clean water to clean all remaining detergent. Use a wet vac or floor squeegee to remove excess water and aid in drying. Let the floor dry overnight, then move things back into the garage.

How to Clean Epoxy Garage Floor

Epoxy-coated floors need a gentler approach to avoid damaging the finish.

1. Sweep or vacuum the floor.
2. Mix 1 gallon of warm water with 2–3 ounces of ammonia or a pH-neutral cleaner.
3. Mop the surface—avoid using citrus or vinegar-based cleaners as they can degrade epoxy.
4. For stuck-on grime, scrub gently with a soft-bristle brush.
5. Rinse thoroughly and let it air dry or use a microfiber mop to finish.

Avoid pressure washing epoxy garage floors at close range, as it can chip the coating.

How to Clean Concrete Garage Floor:

1. Mix warm water with a heavy-duty degreaser or detergent.
2. Mop or spread the solution across the surface using a stiff-bristled broom.
3. Allow the cleaner to dwell for 10 minutes.
4. Scrub with a brush or use a power scrubber for large areas.
5. Rinse thoroughly using a pressure washer or hose.
6. Squeegee excess water toward the drain or vacuum it with a wet/dry vacuum.

This method works for most unsealed and sealed concrete garage floors.
