Both the metal copper and brass can be cleaned using regular dish soap solution, whereas appropriate uncoated items can be cleaned using lemon and salt or tamarind or copper and brass cleaner for cleaning the tarnished areas. It is advised that an appropriate cleaning method should be used based on the finish of the item, and it should be ensured that all the cleaning material is rinsed off and the item is dried completely.
The following tips will help you understand various methods of cleaning your copper and brass items.
Why Do Copper and Brass Lose Their Shine?
Copper is reddish-brown in color while brass is an alloy primarily composed of copper and zinc. They both can slowly discolor over time due to exposure to air, water, fingerprints and other residues.
Some examples are:
-
Dull or brown surface
-
Dark spots on areas often touched
-
Grease and soot at diya holder areas
-
Green or blue-green color on some surfaces of copper
Not all of them are ordinary dirt. Some are actually tarnishes or corrosion which may not be removed by just regular cleaning.
It would be useful to keep in mind that a darkened surface does not necessarily mean that there is a problem. The patina in some antique and decorative items adds to its appeal and value.
Before Cleaning: Check the Metal and Its Finish
Not every copper- or brass-coloured item can be cleaned in the same way. Check these points first.
1. Is it solid brass or brass-plated?
The magnet could provide an indication. If the magnet attaches well, then it might be an object which has steel or iron core with brass surface coating. Nevertheless, using a magnet to test for authenticity of brass is not an accurate test.
If the object is likely plated brass, do not use scrubbing agents because the surface can easily be stripped away.
2. Does it have a protective coating?
There are some copper and brass objects that come with a lacquer coating in order to preserve their gloss. If the surface is coated and looks smooth, then do not use lemon, vinegar, salt, and metal polish on them even when suggested by the manufacturer. Instead, clean them using a soft cloth dipped in soapy water.
3. Does it have decorative details?
These idols, jewelry, antiques and decorative items might include stones, paints, enamel, gilding, etc. Acid and rubbing might harm these features.
In case you are not sure what material and what finish it is, use the most careful cleaning technique.
It is always advisable to test the method on a small piece first.
What You Need for Basic Cleaning
For cleaning regular dirt, have the following on hand:
-
A soft cotton or microfiber cloth
-
Mild dishwashing detergent
-
Lukewarm water
-
A soft-bristled brush for cleaning visible crevices
-
A clean and dry cloth
There are some people who use lemon, tamarind, or vinegar-based solutions to remove tarnish. This is an acidic method and does not suit all finishes or materials.
4 Ways to Clean Copper and Brass at Home
1. Mild Soap and Water for Everyday Dirt
In case your copper or brass object is dusty, fingermarked, greasy or lightly soiled, try the easiest technique.
-
Mix some mild liquid dishwashing soap into slightly warm water.
-
Wring out a soft cloth using the mixture.
-
Gently rub the surface.
-
Wipe away soap with a clean damp cloth.
-
Dry the object completely.
This technique is a perfect beginning of any regular cleaning. It will not help you eliminate existing tarnishing, but it will aid in eliminating dirt from the surface without unnecessary polishing.
Use the manufacturer’s recommendations for objects that have coating.
2. Lemon and Salt for Suitable Uncoated Items
Lemon juice is acidic, and salt can add abrasive action. Some people use this combination to brighten tarnished copper and brass.
However, it should not be treated as a universal cleaning solution. Salt and acidic mixtures can affect delicate finishes and leave residues, particularly if they are not rinsed away properly.
If the item is suitable for this method:
-
Test a small hidden area first.
-
Use a small amount of lemon juice and salt on a soft cloth.
-
Rub very gently without applying heavy pressure.
-
Do not leave the mixture sitting on the surface.
-
Rinse thoroughly and dry immediately.
Avoid this method on lacquered, plated, antique or valuable items.
3. Tamarind or Vinegar-Based Cleaning Paste
Tamarind and vinegar are two of the substances that are considered to be acidic, which are occasionally used in the traditional technique of metal cleaning.
For instance, a paste for household use can be prepared using an equal portion of flour and salt, to which white vinegar is added to make a paste.
But such a mixture may not suit all copper or brass items. Acidic substances and salt may harm the finish of certain items.
In case you decide to try this home remedy, ensure that the item is uncoated and fit for it.
Antiques, plated items, and those whose finishes are unknown should not undergo this process.
4. Use a Copper and Brass Cleaner
Home remedies can take time and may not work for all types of tarnish. Another alternative is to use a commercial cleaning solution which is made specifically for copper and brass.
The Astro Plus Copper & Brass Cleaner (300 ml) is specified for copper and brass objects like utensils, pooja articles and decorative items.
Before using the product:
-
Check the product label for appropriate surfaces and directions for use.
-
Test the product on a small and inconspicuous surface area.
-
Use and clean as per instructions provided on the product packaging.
-
Wipe off the product as per instructions.
-
Dry the object thoroughly.
It should not be assumed that a product suitable for one copper or brass object will suit all copper or brass finishes.
Cleaning Copper Bottles and Cookware
A few extra precautions should be taken when dealing with copper bottles and cookware as the part which comes into contact with food is very important.
Look for the inner coating of copper products.
Sometimes the lining of the copper cooking utensils is made of tin, known as kalai. Those cleaning methods which can be applied on the outer surface of copper should not be assumed for the lining too.
Take precautions when handling food and drink with the copper bottle or cookware.
Uncleaned copper can interact with foods and beverages that contain acids.
Follow the manufacturer's instructions concerning the safe contents for this particular container.
Clean after polishing.
If the utensil is polished or cleaned with any metallic substances, always follow the instructions of the product. Wash the utensil thoroughly with detergent and run water before using it for food or drink.
Common Mistakes to Avoid When Cleaning Copper and Brass
The use of steel wool or rough scrubbies: They may scratch the soft metallic surface.
-
Applying acidic solutions for an extended period of time: Lemon, vinegar, and tamarind solutions can spoil the finish.
-
Application of the same technique to every object: Lacquered, plated, and antique objects require individual attention.
-
Neglecting the cleaning solution residue: The remaining cleaning solution can settle in crevices or react with the metal surface.
-
Combining cleaning solutions: No cleaning solutions should ever be combined together, especially the ones which include bleach.
-
Repetition of polishing antiques: This may result in loss of original surface details.
How to Keep Copper and Brass Looking Clean
A little care can save you from having to polish too often.
-
Clean fingerprints, oils, and dust using a soft cloth.
-
Dry objects after cleaning and do not leave water on them.
-
Store objects in a dry place.
-
Do not use wet cloths or inappropriate storage materials for a long time.
-
Remember to follow the instructions of the manufacturer for coated or decorated objects.
The idea is not to make everything look like new. Sometimes it is more important to preserve the original appearance of the object than to restore its shine.
Frequently Asked Questions.
1. What is the best way to clean brass?
The best way to clean brass depends on its finish and condition. If cleaning ordinary dirt from the brass, use gentle dish soap, water, and a soft rag. For old, darkened, uncoated brass, a good brass cleaner may do the trick. Do not use harsh acids or scrub brushes on lacquered, plated, or antique brass pieces.
2. How can I make brass shiny again?
To restore shine to uncoated brass, first remove dust and dirt with mild soapy water. For light tarnish, a suitable brass cleaner or a gentle cleaning method, such as lemon and salt, may help. Rinse away any residue and dry with a soft cloth. Avoid acidic cleaners and abrasive scrubbing on lacquered, plated or antique brass, as they can damage the finish.
3. Can I use lemon and salt to clean copper and brass?
Yes, lemon and salt will work for eliminating light tarnish on uncoated copper and brass objects. Apply the mixture to the object's surface, then rinse and dry right away. It should not be used on any lacquered, plated, antique, or delicate pieces because the acid and salt can ruin their coating.
4. What should I avoid when cleaning brass?
Avoid using rough or abrasive products, constant contact with acidic solutions, or improper cleaning chemicals. Refrain from polishing any lacquer, electroplated or antiques, before reviewing their specific requirements.
5. Why does brass become dull again after cleaning?
Brass becomes dull again because exposure to air, moisture, fingerprints and environmental pollutants causes natural tarnishing. Leftover cleaning residue or harsh scrubbing can also affect its surface. To maintain its shine, rinse away all cleaner, dry the brass completely with a soft cloth and store it in a dry place.
