How to Remove Stains From Pottery
To remove stains from pottery, it is important to avoid using bleach or chlorine as these can damage the ceramic item.
Scrubbing the surface will not remove bacteria stains, which are more likely to occur on earthenware or stoneware pottery due to their higher porosity.
Porcelain, with its low porosity, is less likely to stain.
The most effective process involves soaking the pottery in an 8% hydrogen peroxide bleach solution for several hours, then placing it in an oven at 180-200 degrees Fahrenheit.
Preheated ovens should be avoided to prevent damage.
Stubborn stains may require repeating the process every 24 hours, but results are not guaranteed and glaze flaking or reappearance of the stain-causing material are possible risks.
Note that bleaching may not remove inorganic stains like rust or clay minerals, and crazed or crackled glaze is not food safe.

Understanding The Cause Of Stains On Pottery
Stains on pottery can be a frustrating sight for any pottery enthusiast. These unsightly marks not only take away the beauty of the piece but can also be a breeding ground for bacteria. The culprit behind these stains is often moisture seeping through small cracks in the glaze. When moisture combines with organic matter, it forms bacteria stains, which are notoriously challenging to remove.
Unlike regular dirt or grime, bacteria stains cannot be easily scrubbed off the surface of pottery. This is because the stains penetrate deeply into the porous material, making it difficult for traditional cleaning methods to be effective. Therefore, it is essential to understand the underlying cause of these stains to implement the most suitable removal techniques.
The Risks Of Using Traditional Cleaning Methods
Many individuals mistakenly assume that scrubbing the surface with ordinary cleaning solutions will remove bacteria stains from pottery. Unfortunately, this approach is often futile and can even cause further damage to the ceramic item. Bacteria stains require specialized treatment to ensure complete removal without compromising the integrity of the pottery.
Moreover, some pottery materials are more prone to staining than others. Earthenware and stoneware pottery, with their higher porosity, provide a perfect environment for moisture and bacteria to thrive. On the other hand, porcelain, known for its low porosity, is less likely to stain. Therefore, it is crucial to consider the type of pottery involved and choose the appropriate stain removal method accordingly.
Porosity And Staining: Know Your Pottery Type
Understanding the porosity of your pottery is vital in dealing with stains effectively. Porosity refers to the ability of a material to absorb moisture. Pottery with higher porosity, such as earthenware and stoneware, is more susceptible to staining because moisture can more easily seep through the small cracks in the glaze. In contrast, porcelain, with its low porosity, provides a more resistant surface that is less likely to stain.
When it comes to stain removal, it is important to consider the porosity of your pottery. The method used for removing stains from porcelain may not yield the same results for earthenware or stoneware. Different pottery types require different approaches, so it is crucial to know your pottery type before attempting any stain removal techniques.

The Do’s And Don’ts Of Using Bleach On Pottery
Using bleach or chlorine to remove stains from pottery might seem like a quick fix, but it can have adverse effects on the ceramic item. Bleach and chlorine are harsh chemicals that can damage the glaze and the overall structure of the pottery, leading to irreparable harm. Therefore, it is crucial to avoid using these substances when attempting stain removal.
Additionally, heating stained pottery in an oven is not recommended. This can cause the stain to spread further and create more damage. Preheated ovens should especially be avoided as they can easily crack or break the delicate pottery. Care must be taken to protect the integrity of the piece during the stain removal process.
To summarize:
- Do not use bleach or chlorine to remove stains from pottery
- Avoid heating stained pottery in an oven, as it can cause more damage

For more stubborn stains, a stronger solution is necessary. Follow these additional steps:
- Soak the pottery in an 8% hydrogen peroxide bleach solution for several hours. This allows the bleach to penetrate the stains deeply.
- After the soaking process, place the pottery in an oven set between 180-200 degrees Fahrenheit. Be cautious not to exceed this temperature range.
The gentle heat helps activate the bleach and aids in stain removal.
Remember to always handle pottery with care when attempting stain removal.
Important Considerations For Stain Removal Process
During the stain removal process, it is essential to keep a few important considerations in mind. Always avoid using a stronger solution of hydrogen peroxide bleach than recommended, as it can be dangerous and should be handled by professionals. Furthermore, the effectiveness of the peroxide solution diminishes after exposure to light for a day, so it is crucial to plan the stain removal process accordingly.
It is important to note that the results of the stain removal process are not guaranteed or 100% predictable. There is a possibility of glaze flaking and the reappearance of the material causing the stain.
