How to Clean Garage Floor Easily?

Concrete floorings are as durable and stain-resistant as many homeowners believe. Thick liquids like oil and chemical can quickly penetrate the concrete surface to leave a permanent mark. Water spilled on the clean floor can easily seep into the surface to create moisture. This can become a nightmare for garage owners with expensive ceramic tiles.

The only option is to keep your garage clean and maintained. Cleanliness is vital to keep your garage floor new at all times.

It gets harder to remove debris, dust, and fuel spills from the garage floor after they have dried out; hence it’s a great idea to give your garage floor a thorough wash every week. You can apply solid detergents and pressure washer methods to remove the permanent stain or debris if they don’t seem to come off with a regular wash!

Step by Step Method to Clean Garage Floor

Here is a complete guide to clean the garage floor.

Prepare your Garage

Before you start, don’t forget to prepare the area for cleaning. Tidying the garage is often a part of garage floor cleaning.

Remove Objects

Remove every object from the floor. Start by removing large items such as vehicles, basins, lawnmowers, boxes, etc. Next, you can pick up small items such as screws, tools, etc. Be careful about using a vacuum cleaner in the garage; use a sweeper instead.

Protect Outlets and Drywall

The drywall inside the garage is prone to water damage. Mold and mildew can quickly grow on walls with soaked-in moisture.

Cover at least 2-ft of the drywall with a tarp or plastic. Cover the electrical outlets along the wall.

Remove Stain


Once you’ve removed objects and secured the drywall, it’s time to determine the stain type.

A soap water solution works best in most garage floor cleaning, but it might not fare well against strong stains that of chemical spills, hot tire marks, and kitty litter.

Here are some proven methods to remove stains permanently.

How to remove oil and grease stains?

The occasional oil spill is inevitable in a garage. Every fuel-powered engine spills oil, including a car, bike, generator, and lawnmower. Over time, the oil spill can turn into a thick and stubborn stain that won’t easily come off with detergent.

Here is how you can effectively remove oil and grease:

For Fresh Oil Spill

Cleaning with sawdust
  • Start with sprinkling some sawdust or cat litter over the spill to absorb the liquid. Sweep it up and dispose of it properly.
  • Next, pour some dry dish soap onto the stain and let it sit for an hour. Pour some water over it and start scrubbing with a nylon-bristle brush (Avoid using a metal brush). Let the solution rest for a while before scrubbing again.
  • Rinse the floor with a power jet wand and remove the liquid with a cloth.

For Old Oil and Grease Stain

  • Use natural acid to remove the stubborn stain. You can use lemon juice or vinegar to work on the stain. Pour white vinegar or squeeze lemon onto the stain and let it sit for five minutes.
  • Use a stiff brush to scrub and scour the stain.
  • Rinse the floor with water. If you still find traces of debris, consider giving it a second scrub with natural acid.

How to Remove Rust Marks?

Rust marks are often left by old machinery, metal parts, garden tools, and metal buckets when left alone for a long time. Moisture is one of the biggest foes of metal that can lead to rusting.

The stain mark won’t leave the concrete floor quickly. It requires an intense clean for the garage floor. You can depend on the natural acid (lemon or white vinegar) and muriatic acid to remove the stain.

Cleaning for rust floor
  • Pour the solution directly onto the stain and let it sit for 10 minutes. Use a nylon brush to work on the stain and then rinse the floor with water.
  • Repeat the step if the traces of rust are still visible.

How to Remove Sealer and Old Paint Colors?

Paint stain removal

Paint and sealer stains are the toughest. The industrial paint sticks to the floor surface and leaves a nasty mark.

  • Start with a putty knife to scrape off loose paint and then sweep the area.
  • Make a Trisodium Phosphate (TSP) and water solution and carefully pout it onto the spot. Let it sit for a while before scrubbing it.
  • Rinse with water. You can scrape off the remaining bits using a putty knife.
  • As an option, you can use a commercial paint stripper to remove tough paint marks. Let the solution sit on the stain for several hours before scraping and scrubbing.

You can install different epoxy floorings, including epoxy mortar floor, epoxy flake floor, self-leveling epoxy paint, and anti-static epoxy floor.
