How to Clean Clay

Cleaning clay, whether it’s from pottery making, sculpting projects, or merely the remnants after a day of creative exploration, requires a methodical approach to ensure that your tools, workspace, and creations remain in prime condition. This process not only helps in maintaining cleanliness but also extends the longevity of your materials and tools.

In the following sections on how to clean clay, we will guide you through the essential steps to effectively clean clay from different surfaces and tools, ensuring your creative space is both welcoming and conducive to inspiration.

Types of Clay and Their Characteristics

Before delving into the various cleaning methods, it is essential to understand that there are different types of clay and each type has different characteristics. This knowledge will help you determine which method works best for the specific type of clay you are working with. The three main categories of clay are:

Earthenware

This type of clay is opaque in color and can be found in various shades of brown, red, and tan. Earthenware clay is suitable for beginners as it is easy to work with due to its high plasticity. However, this type of clay tends to crack easily when drying and requires a glaze to make it waterproof.

Stoneware

Stoneware is typically gray or white in color and is known for its durability and strength. This type of clay is more challenging to work with due to its low plasticity, but it produces beautiful results when fired at high temperatures.

Porcelain

Porcelain is a type of white clay that has a smooth texture and high plasticity. It is the most delicate among the three types and requires special care when working with it and cleaning it.

Knowing the characteristics of each type of clay will help you understand how to clean them effectively without damaging your creations or tools. It is important to note that some types of clay may have additives such as grog or sand, which can affect its cleaning process.

Tools and Materials for Cleaning Clay

Before starting the cleaning process, it is essential to gather all the necessary tools and materials to ensure a smooth and efficient cleaning experience. Some of the basic items you will need are:

A Plastic Scraper or Metal Rib:

These tools come in handy for scraping off excess clay from your workspace or tools.

A Bucket or Sink:

A bucket or sink will be used to soak and rinse your tools, depending on their size and the amount of clay residue. Make sure to use a designated cleaning bucket/sink to avoid cross-contamination with food or other materials.

Water Source:

Having a nearby water source, such as a faucet or hose, will make the cleaning process easier and quicker.

Sponge:

A sponge is useful for wiping away any leftover clay residue from your tools or workspace.

Soap:

Mild dish soap or hand soap can be used to remove stubborn clay stains from your hands and tools. Avoid using harsh chemicals that can damage your tools or irritate your skin.

Towels:

Have a few clean towels nearby to dry off your tools after cleaning.

11 Step-by-step Guidelines on How to Clean Clay

Step 1: Prepare Your Workspace

Lay out old towels or newspapers on your work surface to protect it from any clay residue. This will make the cleaning process easier later on. It is also a good idea to have a designated workspace for cleaning clay to avoid cross-contamination with other materials. Building a cleaning station with a plastic sheet or tarp can be useful for containing any mess. You can also use an old baking tray as a portable cleaning station.

Step 2: Scrape off Excess Clay

Using your plastic scraper or metal rib, scrape off any excess clay from your tools and workspace. This step will make the cleaning process easier and prevent clay from clogging up your sink or drain.  If you are working with a relatively small amount of clay, you can skip this step and go directly to soaking your tools. But if you are cleaning a larger amount of clay, it is essential to scrape off as much excess clay as possible.

Step 3: Soak Your Tools

Fill your designated bucket or sink with warm water and let your tools soak for at least half an hour. This will loosen up any dried-on clay residue and make the cleaning process easier later on. It is recommended to use warm water as hot water can cause the clay to harden and cold water may not be as effective in breaking down the clay. The length of time for soaking may vary depending on the type and amount of clay residue. You may need to soak your tools longer for stubborn clay stains.

Step 4: Remove Tools from the Water

After soaking, remove your tools from the water and rinse them off with clean water. Use a sponge or brush to scrub away any remaining clay residue. If some residue is still present, you can repeat the soaking process until it is completely removed. It is essential to rinse off all cleaning solutions and clay residue before drying your tools to avoid any potential contamination. You can also use a metal scrubber for more stubborn stains, but be cautious not to damage your tools.

Step 5: Dry Your Tools

After rinsing, use a clean towel to dry off your tools. Make sure they are completely dry before storing them away or using them again. If you are using metal tools, it is recommended to apply a thin layer of oil or lubricant to prevent them from rusting. It is also a good idea to store your tools in a clean and dry place to avoid any potential contamination. The same goes for your workspace; make sure to clean and dry it after each use.

Step 6: Clean Your Workspace

Once your tools are cleaned, you can move on to cleaning your workspace. Use a sponge or cloth with warm water and soap to wipe down your work surface. If there are any stubborn clay stains, you can use a metal scrubber or a mixture of vinegar and baking soda to remove them. It is essential to dry your workspace thoroughly after cleaning to avoid any potential damage or contamination. You can also use a clay-specific cleaner if you want to, but make sure to follow the instructions carefully.

Step 7: Clean Your Hands

After handling clay, it is necessary to wash your hands thoroughly. Use warm water and soap to remove any clay residue from your hands. You can also use a pumice soap or hand scrub to get rid of any stubborn clay stains. It is essential to dry your hands properly after washing, as wet hands can introduce moisture into your clay and affect its quality. The same goes for any tools you may use to clean your hands; make sure they are clean and dry.

Step 8: Clean Your Clothes

If you accidentally get clay on your clothes, it is best to remove it as soon as possible. You can use a plastic scraper or toothbrush to gently scrape off the excess clay before washing the garment. It is recommended to pre-treat the stain with a mixture of vinegar and baking soda before throwing it in the wash. Avoid using hot water, as it can cause the clay to set in permanently. It is also helpful to have designated clothes for working with clay to avoid damaging your regular clothes. Baking soda or oxygen bleach can also be used as a pre-treatment for clay stains.

Step 9: Clean Your Cleaning Tools

After each use, it is essential to clean your cleaning tools thoroughly. Rinse off any leftover clay residue and dry it before storing it away. It is recommended that certain cleaning tools be designed specifically for working with clay to avoid cross-contamination with other cleaning tasks. You can also use a mixture of vinegar and baking soda to disinfect your cleaning tools. The same goes for your cleaning bucket or sink, make sure to clean and disinfect it after each use.

Step 10: Clean Your Cleaning Station

If you have used a designated cleaning station, make sure to clean it after each use as well. Use warm water and soap to remove any clay residue before drying it completely. It is recommended to store the plastic sheet or tarp in a clean and dry place to avoid any potential contamination. If you are using an old baking tray, make sure to wash it thoroughly before using it for food again. It is also helpful to have a separate cleaning station for clay-specific tasks to avoid any cross-contamination with other materials.

Step 11: Dispose of Clay Residue Properly

After cleaning your workspace and tools, you may have leftover clay residue that needs to be disposed of properly. You can let it dry completely and then throw it in the trash. You can also recycle clay by letting it dry, crushing it into a powder, and mixing it with water to form new clay. Avoid pouring any leftover clay residue down the drain as it can clog your pipes and harm the environment.

Following these steps on how to clean clay will not only help you clean your tools and workspace effectively, but it will also prolong the life of your tools and ensure that you are working with uncontaminated clay. It is essential to make cleaning a regular part of your clay routine to keep your tools in top condition and maintain a safe and hygienic workspace for yourself and others. Happy creating!

Restoring Old or Dried-Out Clay

If you have old or dried-out clay, there are a few steps you can take to restore it to its original state. First, try adding water gradually and kneading the clay until it becomes pliable again. You can also try storing it in an airtight container with a damp cloth or paper towel for a few days to allow the moisture to penetrate the clay. If these methods do not work, you can try adding a small amount of glycerin or mineral oil to the clay and kneading it until it becomes soft again.

However, keep in mind that using additives may affect the properties of your clay, so use them sparingly. If all else fails, it may be time to retire the old clay and start with fresh supplies. Properly store your clay in an airtight container or bag to prevent it from drying out again.
