What Causes Stains on Garage Floor Epoxy?

There are a few different things that can cause stains on your garage floor epoxy. The most common culprit is oil and grease. If you have a car that leaks oil or if you store any oil-based products in your garage, then you are likely to see stains on your floor.

Another common cause of stains is road salt. In the winter, road salt can be tracked into your garage on your car’s tires. This salt can cause the epoxy to deteriorate over time and can also leave behind ugly stains.

Additionally, if you have a pet urinating in your garage, you may also see stains on your floor. The other main cause of stains is simply dirt and debris. Even if you are diligent about sweeping and mopping your garage, dirt and dust can still find their way onto your floor and cause stains.

Lastly, if you have ever had a car leak antifreeze, then you know that this can also cause some serious staining.

Some Easy Ways How to Clean Garage Floor Epoxy

Step 1: Gather Necessary Cleaning Supplies

Before starting the cleaning process, gather all the necessary supplies. These may include a broom or vacuum, a mop, a bucket, mild detergent or cleaning solution, and a scrub brush or deck brush. Having all your cleaning tools ready beforehand will make the process more efficient and convenient.

Step 2: Remove Debris and Dust

Begin by removing any debris, such as leaves, dirt, or small objects, from the garage floor. Use a broom or vacuum to sweep the entire surface, ensuring that all dust and dirt particles are removed. This step is crucial, as it will prevent the debris from scratching or damaging the epoxy surface during the cleaning process.

Step 3: Prepare Cleaning Solution

In a bucket, mix a mild detergent or cleaning solution with warm water. It is essential to use a non-abrasive cleaner to avoid damaging the epoxy floor. Read the manufacturer’s instructions for the recommended cleaner-to-water ratio and adhere to their guidelines for optimal results.

Step 4: Apply Cleaning Solution

Using a mop or deck brush, apply the cleaning solution to the garage floor. Start at the farthest corner of the garage and work your way towards the entrance. Ensure that the entire floor is covered with the cleaning solution, taking care to apply an even layer.

Step 5: Scrub the Floor

For heavily soiled areas or stubborn stains, use a scrub brush or deck brush to agitate the surface. Apply gentle pressure and move the brush in circular motions to loosen the dirt and grime. Be cautious not to apply excessive force, as this may scratch or damage the epoxy coating.

Step 6: Let the Solution Sit

Allow the cleaning solution to sit on the floor for a few minutes to break down dirt and stains. The length of time needed will depend on the level of soil and the specific cleaning solution used. Check the manufacturer’s instructions for their recommended dwell time.

Step 7: Rinse the Floor

After the cleaning solution has had time to work, thoroughly rinse the floor with clean water. Use a mop or hose to remove all traces of the cleaning solution, as leaving residue behind can cause the floor to become slippery or attract more dirt. Make sure to rinse the floor from the farthest corner towards the entrance, pushing dirty water out of the garage.

Step 8: Remove Excess Water

Once the floor is rinsed, use a squeegee or mop to remove excess water from the surface. This step will help prevent water from pooling and causing potential damage to the epoxy coating. Additionally, removing excess water will speed up the drying process.

Step 9: Dry the Floor

Allow the floor to air dry completely before moving vehicles or other items back into the garage. The drying process can be expedited by using fans or air movers. Ensure the floor is entirely dry to prevent slips and falls, as well as potential damage to the epoxy surface.

Step 10: Inspect for Damage

After the floor is clean and dry, inspect the epoxy coating for any signs of damage or wear. This includes checking for scratches, peeling, or discoloration. If you notice any issues, consult a professional or refer to the manufacturer’s instructions for guidance on repairs or maintenance.

Step 11: Maintain a Regular Cleaning Schedule

To keep your garage floor epoxy looking its best, establish a regular cleaning schedule. This may involve sweeping or vacuuming the floor weekly, and deep cleaning with a mild detergent or cleaning solution monthly or as needed. By maintaining a consistent cleaning routine, you can prolong the life of your epoxy floor and ensure it remains in excellent condition.
