Rock and Mineral Cleaning

How to Rock and Mineral Cleaning?

Any site’s rocks are rough and dusty when you first collect them. They require extra luster and brightness, or if you discover a gem in a nearby park or at your residence, you want to give it a shining, moist appearance.

Dirt and grime are not entirely removed by running water. You correctly clean your specimens using the right cleaning techniques. You may rapidly add an amazing rock to your collection in this method after collecting it.

Depending on the type of rock you are looking for and polishing, as well as how much time you spend polishing rocks.

Best Methods for Rock and Mineral Cleaning:

Selecting the right gemstone for polishing is the first step. Some stones do not polish because softer rocks can be damaged by abrasives, and over time they absorb their finishes and become dull. Going with the harder stones is preferred if you want a wet-looking finish.

Next, you keep yourself safe by wearing protective clothes and gloves before applying any polish to your stones. Gloves protect you from rock shards as well as chemicals when finished. You can use special masks to conceal your eyes or other facial features as additional protection.

First, try a scrub with a nylon or brass brush and soap bar. You can also use the toothbrush. Also, wash them with running water. This thing will get most of the dirt away, and you can follow the methods to deep clean your rocks.

Before using any cleaning process on your specimens, always do your research on their chemical makeup.

Mechanical Way:

Following is the best way to make your rock look incredible. These are one of the best methods, but chemical cleaning can ruin your stones, so that you can do this with full consideration.  


  • To get rid of as much debris and dirt as possible, brush the rock.
  • Place the specimen on the newspaper or other paper and lay it flat.
  • The rock may be cleaned with a nylon brush or toothbrush.
  • After cleaning the stone, soft regions can be cleaned with a toothpick or brass brush. 

High-Pressure Water:

High pressure can also be used to get rid of dirt. Avoid using too much water pressure on your rock to prevent damaging your specimen.

Allow the rock to dry a while between cleaning. Repeat this process until you want.

Brushing and Probing the Dirt:

Dental probes are ideal for getting muck and debris out of a stone’s tiny cracks and crevices. Another option is a wire brush.

You can use brass brushes also, but the soft mineral specimens can destroy by these brushes.

Ultra-Sonic Cleaning:

These cleaners could be able to get rid of debris, but you’ll need to use them carefully because the cleaning solution is in a container that vibrates at a very high frequency. This generates bubbles that remove impurities from the stone and peel away materials. But the majority of the mineral specimens might be harmed by this thorough cleaning.

Ultra-sonic cleaner can only use on a more complex mineral. Sometimes these cleaner cause your stone to break and damage the entire stone.


Sandblasting is best used for difficult specimens that require the removal of several matrices. You will need to do more cleanup before the piece is finished because it can easily affect the surface of most minerals. In another instance, it works miracles. You will do less harm to the surface of your stone if you use glass beads as your abrasive media rather than garnet or quartz sand.

Although expensive, it is a useful tool to have on hand if you regularly clean specimens.

Air Scribes:

An air scribe is a difficult tool to beat for large material removal. These tiny tools are simple to locate. They are basically little pneumatic chisels, and they are not costly, if you have an air compressor. They ought to be handled with care. They are careless mistakes that might harm your stone.

Although air scribes depend on the situation, they are the ideal instrument for removing a lot of material to expose the target specimen.

Spot Cleaning Guns:

Spot-cleaning guns are used for clothing as well as on minerals and rocks. Although they are specialized, they are not very pricey and won’t take up much space. Use them to clean rocks and minerals for the first time. In many circumstances, they could be the only tools you require.

Chemical Way:

The oxalic acid is the best for cleaning rocks and minerals; solutions like baking soda, vinegar, hydrogen peroxides, and muriatic acid are effective in cleaning stones, but the answer depends on the specimen you collect.

Listening to the term “acid” for cleaning can be daunting, but there are many solutions you can use for household cleaning, and these are the most effective methods. All the keys work in various ways, but oxalic acid is incredibly effective and offers versatile usability.

Now I will tell you different methods I also use to clean rocks and minerals. If you are interested, let’s find the best strategy for your rock needs.

Cleaning with the oxalic acid:

The oxalic acid powder is affordable and simple to find. The one-pound canister should be simple to locate at your local paint or frame shop. It is also called wood bleach, but before purchasing, confirm with a shop assistant that it is the same product.

Rock cleaning with oxalic acid is among the most effective methods spelling. It is a powerful powder for eliminating iron oxides, which leave rocks and minerals with a dark tint.

This solution is highly toxic and safe to use at home, but you should follow the precautions as it can also absorb on your skin by inhalation. Avoid spilling the solution everywhere, especially on ceramic, and wipe it straight away. 

A plastic container is filled with ¾ full of water, then add oxalic crystal or powder. This solution should be heated to around 110 degrees Fahrenheit using the double boiler system. It is impossible for a plastic container to get too hot instantly, and the solution should never be put directly into a stainless basin.

Although warming the solution can speed up a chemical reaction and cause it to happen in as short as an hour, this is never done. It may be discarded when the solution turns black, which is fantastic for cost-effectiveness, but a new batch must be prepared in exactly the same way.

The stain should not be removed from the rock until this solution has been applied to it fully.

Afterward, you can wash it with simple water to prevent insoluble oxalates from forming, leaving an unsightly yellow stain once the rock dries.

They must be submerged in a 5-gallon bucket with room to spare and a discharge hole at the bottom to soak.

Whether it takes place once per minute for an hour or once daily for a month, you must refill the water as often as possible.

This is the best and most effective method in cleaning the rocks and minerals that sweep any dirt and grime and give you a clean, beautiful, and incredible stone with a flawless appearance.    

  • Clean your rock with soap and water and allow it to dry.
  • First, add 3 gallons of water and 2 pounds of oxalic acid.
  • Place your specimen in a container and cover it.
  • Leave it for 3 days under the sunlight.
  • Remove the rock from the solution and wash it with water.
  • Put the stone back in the solution if it needs to soak for longer.
  • You can use the same response up to six times before the solution turns opaque.
  • Let the rock soak in a solution of baking soda for a few days.
  • Dispose of the acid properly. 

Cleaning with baking soda:

Baking soda is a typical household and is found easily in your cabinet or your nearby general store. This is used in cleaning household items or the home, but also the best way to clean the dirt from the rocks.

When the rock has been thoroughly cleaned, place it in the solution for a few minutes. To make the solution, dissolve the baking soda in a container with warm water.

You can also clean it with a mixture of baking soda and vinegar, which results in a bubbling reaction to remove dirt.

But you can check this solution on the small area of your specimen because some minerals reacted to this mixture, and this way, you may harm your specimen.

Cleaning with the vinegar:

The specimen can be cleaned or freed of dust and metallic brush marks using vinegar and citric acid.

The solution, which may be created with vinegar, can be used to shine or brighten your specimen, such as copper.

  • Put the well-cleaned mineral in a little jar.
  • Put white vinegar over the rock and cover it.
  • Permit them to reflect for a few days or possibly a week.
  • Use runny water to wash the specimen.
  • To finish cleaning the specimen, use a brass brush.

Cleaning from the hydrogen peroxides:

The solution of hydrogen peroxide is not an as effective method, but it is one of the most popular methods that can be used for cleaning. Using it at an incorrect dilution is hazardous to your skin and causes burning and even blindness.

I can only suggest you use this solution if you are experienced. For minerals like copper and phosphate, potassium hydroxide can be utilized as an alternate approach. Additionally, potassium hydroxide isn’t explosive.

  • Properly clean your rock with dish soap.
  • Put the stone in a container.
  • Pour the hydrogen peroxide solution on the rock until it submerges.
  • The bubbles will clean all the dirt.
  • It may take 2 to 3 days to you before a chemical reaction’s apparent indications, including black smoke.
  • Remove the rock from the solution.
  • Rinse the rock with runny water and scrub them with a toothbrush or nylon brush.
  • Wash the rock properly with water,
  • Dry it properly before you put it in your collection.

Cleaning with muriatic acid:

Hydrochloric acid is an alternative name for muriatic acid and is readily available at a wide range of hardware stores. It is an effective method for removing rust, dirt, and even debris.

It can be the best method for removing or cleaning rock and minerals, even than oxalic acid, but it can be hazardous. You can wear protective gloves and clothes and follow complete precautions to stay the way you danger.

This solution can easily remove carbonates such as calcite but does not remove iron oxides more quickly than oxalic acid.

It will remove everything. The rock should be completely washed, dried outside, coated with acid without splashing anything, and placed in a sizable container with room for bubbling foam.

Muriatic acid acts quickly, so that you can check them often. The calcites may be removed from the rock more quickly than the iron oxides by leaving them in the solution for minimum of 5 minutes to maximum of 5 days.

Also, you can use this treatment for removal. You can dilute the acid by adding 1 part acid to 1 part water, and it should not place under the light as it causes a yellow stain.

  • Wash the sample with dish soap.
  • Dry the specimens first, then put them in a glass or plastic container.
  • Please refrain from using any metal as it will react with the acid.
  • Spray some muriatic acid on the stone. Stay away from odors, and watch out for spills.
  • Check the stone regularly.
  • When your specimen clean, wash them with running water for a few seconds.
  • Also, soak the stone in 1 part of the baking soda solution and 1 part of water.


  • Before scrubbing your rock, let it soak in soapy water for a few days to help the dirt come out.
  • Acid should always be added to water
  • If you don’t properly dispose of the acid solution, it might hurt someone.
  • You can keep applying your acid solution up until it becomes black. If it gets dark, you may come up with another option.
  • If you clean a lot of rock, you might want to consider purchasing a tumbler.
  • To clean your rock, always use nylon or brass brushes.
