Step-by-step: How to clean a garage floor

1. Prepare your garage

Before anything else, leave your cars and bicycles outside. Clean the garage and take out boxes, tools, and other knickknacks. This can also be your chance to throw out and recycle things you no longer use. The more floor space you see, the better.

2. Make sure electric outlets and drywall are protected 

You wouldn’t want them to get wet while you’re cleaning the floors! Cover electric outlets with a plastic sheet or tarp, or buy electric socket covers from your nearest hardware store. Consider protecting yourself as well by wearing cleaning gloves, especially if you plan to use strong cleaning chemicals.
 

3. Time to sweep!

FAQs on cleaning garage floors

Power washers — which use hot water — can be useful in removing stubborn dirt and stains. Just make sure to apply a cleaner or degreaser on your floor first. Power wash from the back of your garage and move towards the door. Another alternative is to use pressure washers, which mostly use cold water. 

Power washers and pressure washers are easy to use, but it’s important to read and follow the manual and safety instructions to avoid damaging delicate surfaces. It’s best to hire a professional for complex high-pressure cleaning tasks.

Similar to cleaning a concrete garage floor, all you need to do is make sure the area is free from debris, such as leaves, small rocks, and trash. Wash the floor thoroughly and fill any cracks or holes using concrete filler products, epoxy, or caulking. For complicated repairs, you can consult or hire a floor repair professional

Cleaning epoxy floors has a slightly different process compared to concrete ones. Epoxy floors can resist stains from oil, gasoline, and other chemicals. Still, it’s important to wipe these up as soon as possible. According to All Garage Floors, you should clean the floor with ½ cup of ammonia to one gallon of hot water in a bucket. Avoid soap-based cleaners and vinegar because these can de-gloss the epoxy finish and leave a hazy build-up on your floors.

If it’s a new spill, you’ll need to soak up the oil first. Pour baking soda over it and let it sit for a few hours. Afterwards, scrape the baking soda off the floor. Aside from baking soda, you can also use cat litter, cornmeal, or cornstarch. If you’re working with an old oil stain, you can use store-bought degreasers, enzyme cleaners, or even vinegar to remove them.
