Last updated: April 5, 2018

What Does Acid Cleaning Mean?

Acid cleaning refers to the process of cleaning corrosion products with acidic solutions. Cleaning agents, usually water solutions, can be neutral, alkaline or acidic in nature.

Acid cleaning agents are used to remove scaling and other inorganic deposits. Normally, the active ingredients in such solutions include chelants and mineral acids along with corrosion inhibitors and surfactants.

An acid cleaning may also be known as an acid bath or acid etching.


Corrosionpedia Explains Acid Cleaning

Acid cleaning is a useful method to clean materials and wash away corroded parts. Among the commonly used cleaning agents are hydrochloric acid, also known as muriatic acid. This substance is commonly used for cleaning concrete as well as pools.

Other substances that can be used include vinegar, especially for hard surfaces. This can greatly help in removing build-up of calcium deposits. Another acidic cleaning agent includes sulphuric acid that can be added to drain cleaners to eliminate clogs in pipes by dissolving proteins, grease as well as other elements that cause blockage.

Furthermore, acid cleaners can be highly beneficial in cleaning corroded batteries. When the outer part of corroded batteries starts to seep out, the battery fails to establish contact, affecting the ability of the battery to power a device.

However, it must be noted that acid cleaners can cause damage to skin. Thus, proper protective gear such as gloves should be used throughout the process to prevent burns and other injuries.
