Chemical Cleaning of Metals & Green Vs Chemical Cleaning in the Home

Metal equipment must be cleaned from time to time to prevent damage and maintain efficiency of operation. The chemical cleaning of metals has a number of advantages over mechanical cleaning methods. The greatest of these are that the metal equipment to be cleaned doesn't need to be dismantled and reassembled, and the cleaning doesn't damage the equipment, leaving areas that are more vulnerable to corrosion than before. Metal equipment typically gets both organic and inorganic substances deposited on it, coming from various lubricating oils, corroding metal, deposited product, deposits from hard water etc. These are typically removed in a five step process, although this is varied depending on the exact nature of the scale (deposits). 
Step 1 - Cleaning with alkali Typically this is done with caustic soda (NaOH), and results in the removal of all polar substances such as fats and oils. The vegetable and animal oils are converted to glycerol and soap, and the petrol-derived oils (such as hydraulic oil) are "emulsified" (suspended in water) by any of a variety of emulsifiers. 
Step 2 - Rinsing This loosens the deposits on the metal and washes away both the alkali and the substances that it has removed. 
Step 3 - Cleaning with acid Acids remove any ionic deposits from the metal. The choice of acid depends not only on the price and how strong it is, but on what anion is associated with the hydronium ion. Sometimes a more expensive acid is used because the anion of the cheaper alternative forms an insoluble salt with the ion to be removed. Moreover, some substances, such as silicates, are hard to remove with acid and so a specialised acid (in this case HF) has to be used. 
Step 4 - Rinsing Again, this loosens deposits and removes the cleaning chemical ready for the next stage. 
Step 5 - Passifying with alkali The cleaned metal is now in a highly reactive state, and so it must be coated with a protective layer to prevent corrosion. This is usually done by reacting the metal with an oxidising agent (usually an alkali) to form an oxide layer on the metal. This layer cannot be further oxidised and so protects the metal underneath. The metal equipment can once again be used as it was designed. The scale that was deposited on it is washed away as dissolved ions which are harmless to the environment. 
If you're wondering the difference between green vs. chemical cleaning in the home then you should find out what they can or cannot do for your home. This is because you want to make sure that you get everything you need when it comes to protecting the life of your flooring and the health of your family all at the same time. This is something that allows you to know which would be best for your particular situation when it comes to getting cleaner, healthier carpets quite easily. You will be able to get everything when it comes to having the most, and not having to keep changing your carpets out because of wear and tear.
Green cleaning not only is safer to use in the family because it is made from natural cleaning agents, but it also might be a better option when it comes to being easier on the carpets in the long run for the life of them. Green cleaning is also great for the environment as well. There are no chemicals that can be omitted into the atmosphere which means no more need for pollution when it comes to using the cleaning agents in your home. Chemical cleaning can become irritating to the eyes and senses when used, and the smell might not be the best and stays for a while. Using the green alternatives, you will see that there is no funny smell and it does not irritate the senses.
