Step 1- Remove Dirt Properly

First of all, you must remove all kinds of dirt and grease from your garage surface. You can clean the dirt with a brush or vacuum cleaner.

Keeping up baking soda in a nearby area is a good idea. Because if necessary, it can neutralize the acid. Take a bucket and pour it with water. Now, it’s time to add acid to this water. Take great care to avoid any unwanted acid spills. 

Step 3-Apply the Acid

One of the important things you must remember during concrete wash is you have to keep the entire concrete surface wet. Otherwise, the cleaning process will not be effective and you may also face unexpected acidic situations.

That is why rinse the entire area properly with a hose pipe. You should cover everything in the surroundings. Make sure that the concrete surface will be wet the entire time. You can use a plastic watering can for applying the acid mixture.

Don’t pour the entire can at a time. You need to formulate a strategy to avoid any accidents. In a general sense, your plastic can is capable to handle acid of this concentration for up to one hour. So, your strategy will be working in the small sections of your garage floor.

Also, keep several plastic watering cans ready in your hand if you need to do any kind of replacements. Another important thing is you must always follow the manufacturer’s instructions while adding acid to the water.

Step 4-Brush the Acid

After applying the acid to the floor, you must brush it properly. You can use a push broom to get the job done. Brushing the acid is so much important as it will ensure that every spot is getting covered by the acid.

When applying the acid, the floor must be wet. So, you need to be so much care to ensure that. After brushing up the floor, you must wait for 5-10 minutes so that the acid can sit perfectly. 

Step 5-Neutralize the Acid

Now, it’s time to neutralize the acid. You can use baking soda, garden lime, or any other acid-neutralizing product. Whatever product, you are using make sure that you will apply it properly. After applying, wait for ten minutes so that it can neutralize the acid properly.

Step 6- Rinse Properly

At this point, you need to rinse the floor with water properly. Rinsing the concrete surface at this stage will ensure that all kinds of residues will be washed out and you’ll get a clean garage floor.
