How to Safely Use Muriatic Acid for Pressure Washing: Step-By-Step Guide

Many areas of our home are covered with concrete, from the driveway and sidewalk to patios, decks, and structures. These surfaces can be pressure washed to remove dirt and stains, but sometimes pressure washers alone aren't enough. In these cases, many turn to muriatic acid for pressure washing. However, muriatic acid can be dangerous and should be used with caution.

In this article, we'll cover the advantages and disadvantages of pressure washing with muriatic acid, as well as some tips and tricks on how to use it safely. Plus, we'll even offer some alternative recommendations to pressure washing with muriatic acid. Let's dive in!

What Is Muriatic Acid, And What Is It Used For?

Muriatic acid is a form of hydrochloric acid with a high concentration of hydrogen chloride gas dissolved in water. It is highly corrosive and can cause burns or irritation to the skin, eyes, and respiratory system. In addition, it is a very powerful pressure-washing chemical.

Muriatic acid can pressure-wash concrete surfaces to remove dirt, grime, grease, oil stains, rust stains, and other stubborn residues from hard-to-clean surfaces. It is also used to clean and etch concrete, masonry, brick, stone, and other hard surfaces.

Advantages of Pressure Washing with Muriatic Acid

Brightens Concrete

The most common use of pressure washing with muriatic acid is to brighten concrete. The acid reacts with the surface, creating a whiter, brighter finish that can make it look like new. This can help restore the look of your concrete surfaces and make them look more aesthetically pleasing.

Removes Rust Stains And Oil Stains

It can be difficult to remove rust stains and oil stains from concrete surfaces without pressure washing with muriatic acid. Muriatic acid reacts with these contaminants, breaking them down and removing them from the surface. This leaves behind a much cleaner surface that looks better than it did before.

Eliminates Mineral Stains

Mineral stains are caused by the buildup of calcium, magnesium, and other minerals on the surface of the concrete. Pressure washing with muriatic acid can help to break down these stains and remove them from the surface, leaving it much cleaner.

Removes Paint Splatter

Paint splatter on concrete can be challenging to remove without pressure washing with muriatic acid. The acid reacts with the paint, breaking it down and making it much easier to pressure wash away.

Effectively Cleans Patios, Sidewalks, Driveways, And Other Surfaces

Using soap and water won't be enough to clean patios, sidewalks, driveways, and other hard surfaces. But pressure washing with muriatic acid can effectively remove dirt, grime, grease, oil stains, rust stains, and other stubborn residues from these surfaces.

Disadvantages of Pressure Washing with Muriatic Acid

Highly Corrosive and Dangerous To Handle

Muriatic acid is a highly corrosive chemical and can be dangerous to handle if not done correctly. It can cause burns and irritation to the skin, eyes, and respiratory system, so you must use appropriate safety measures when pressure washing with muriatic acid.

Can Cause Health Problems If Inhaled Or Touched

Muriatic acid can cause health problems if it is inhaled or touched. When pressure washing with muriatic acid, you should always wear protective clothing, including gloves and eyewear.

The Acid Can Damage Plants And Grass

The acid in muriatic acid can harm plants and grass if it is not used responsibly. Therefore, you should take precautions when pressure washing with muriatic acid near flower beds, gardens, or other areas with vegetation. Spraying them with a hose prior to any pressure washing with muriatic acid is generally a good idea to help dilute the mixture.

Requires Protective Gear For Safety

Typically, pressure washing with muriatic acid requires full protective gear for safety. This includes gloves, eyewear, and other protective clothing to prevent exposure to acid.

Step-by-Step Guide To Power Washing With Muriatic Acid

1. Start by preparing the area you will be using for power washing. Remove all items from the area you want to clean and cover any plants or fragile items in the surrounding vicinity with tarps or plastic sheeting. Alternatively, you can use water to soak any plants or soil to ensure the cleaning solution is diluted if it makes any contact with the plants or soil.
2. Put on protective gear such as chemical-resistant gloves, goggles, and a respirator covering your nose and mouth. This is essential to prevent any injuries or hazardous exposure to the acid.
3. Mix 1 part muriatic acid with 10 parts clean water in a large bucket or container until fully combined, then put aside for later use. It is important to add the acid to water – not the other way around – to prevent splattering and increase safety precautions.
4. Apply a coat of your muriatic acid mixture using a pump sprayer. Let it sit for up to 15 minutes.
5. Turn on your power washer or rinse the mixture off of your concrete pad. You may need to
6. Rinse off either with a power washer or hose on the areas that have been treated with muriatic acid thoroughly before continuing any further work, making sure there are no gaps between cleaning sections that might leave residues that could cause damage over time; this is especially important when cleaning masonry material like bricks!
7. Allow treated surfaces ample time to dry before applying any other chemicals or pressure washing any other surfaces.
