How to Neutralize Muriatic Acid: The Useful Tips

The question of how to neutralize muriatic acid needs to be answered. In many industrial usages, muriatic acid, also known as hydrochloric acid, is employed frequently for cleaning.

This chemical material is useful for cleaning up rust, moss, and hard-to-remove stains. However, this chemical is hazardous and has corrosive effects. They have to get neutralized properly.

How to Neutralize Muriatic Acid on Metal

If you use acid on metal, particularly to remove rust, you need to neutralize the whole thing carefully. The metal substance will likely corrode if the muriatic acid is improperly washed off.

If the muriatic acid is concentrated on the metal, dilute it with clean water. Slowly add water to the affected area, remember that you should never pour water into concentrated acid. The dilution process will reduce the strength of the acid.

There are several materials here that you can use to clean up the residual muriatic acid. Read them below, and you will understand how to neutralize muriatic acid from metal substances.

How to Neutralize Muriatic Acid on Metal

1. Using Sodium Bicarbonate (Baking Soda)

Many people often ask, ‘What is muriatic acid used for’. The acid works well in cleaning up hard stains and permanent flaws on many surfaces, including metal. Just like any stains, baking soda can be used to neutralize the acid for sure.

Use diluted baking soda or sprinkle it on the metal surface and let it sit for a few minutes before raising it.

2. Using Nitric Acid

Nitric acid can be used to neutralize muriatic acid properly. It works well on larger surfaces of the metal and on things like rusting pools, too.

Yes, to neutralize muriatic acid for pools, dilute 1 part of nitric acid to 2 parts of water. Use this solution to clean up the metal surface and neutralize the acid residue left there.

How to Neutralize Muriatic Acid on Concrete

Muriatic acid is also used often to clean up the concrete area. They are useful for killing off any vegetative or moss sticking on the concrete.

If the acid residue is not cleaned, though, it will leave some permanent stains. To properly clean up the acid and entirely get rid of it, read the tips on neutralising muriatic acid on the concrete right here.

How to Neutralize Muriatic Acid on Concrete

1. Using Hot and Cold Rinses

Altering between the hot rise and cold rise can help to remove the residual acid from concrete. You can do it by filling the spraying gun with hot water and cleaning up the concrete.

Then, replace the hot water with cold water and respray the surface. It will help to neutralize the muriatic acid on the concrete surface.

2. Using Ammonia

Prepare 6-8 ounces of powdered ammonia. Then, dilute them in 1 gallon of water. Stir the mixture well before transferring them into a spraying gun.

Spray the mixture onto the concrete. The ammonia will neutralize the muriatic acid residue left on the surface, thus preventing any stains from forming on the surface.

How to Neutralize Muriatic Acid on Skin

One of the most important things to remember about this acid chemical material is that they are seriously dangerous for your health.

That’s why humans should not get exposed to them directly.

This is also why protective clothing, gloves, and face shields are needed when applying muriatic acid. If the skin is exposed to the acid, here are some methods for neutralizing muriatic acid and preventing worsening.

1. Using Disinfectant Soap

The first thing you can do to stop the corrosive acid from damaging your skin is to rinse the infected area in cold, running water. Then, use disinfectant soap to clean it up even more.

After that, the pat dries the infected skin, wraps it with a sterile cotton bandage, and calls 911 or seeks medical help immediately.

2. Using Anti-Bacterial Cream

If you have an anti-bacterial cream at home, you can also neutralize the acid. Apply a dollop of them onto the infected area.

That is to ensure that the residual muriatic acid does not mess around with your working site and your skin.

Please remember that this substance is not one to take for granted, as it has a toxic in it and corrosive effect. After understanding how to neutralize muriatic acid, you should always remove it properly after using the acid.

Dispose of the neutralized muriatic acid and the neutralizing solution according to your local regulations. Typically, it’s safe to dispose of small quantities down the drain with plenty of water. Larger quantities may require special disposal methods.
