As a Borosilicate glass enthusiast, one thing I need to do is to always keep it clear of dirt and stains so that I get the most out of it, whether for kitchen or laboratory use.

That is why we will be explaining the different efficient ways how to clean Borosilicate glass with simplicity and maintain its pristine state.

We will begin with how Borosilicate glass is made, then move on to understand why it is dishwasher safe and how to sterilize it.

Finally, we will provide tried-and-true strategies for keeping your Borosilicate glass immaculate, allowing you to utilize its unique qualities while also increasing the longevity and performance of this versatile glass material.


There are several manufacturers of Borosilicate glass, and while each brand has its manufacturing process, there are some standard techniques that they all follow.

Here’s how borosilicate glass is made: Sand is mixed with chemicals such as sodium oxide, boric oxide, and recycled glass before being put into a furnace that burns at approximately 1550 degrees Celsius.

Inside this furnace, there are several burners and separate chambers where this sand and chemical mixture is continually fed and melted by intense heat.

In one of the chambers, chlorine and gas are pumped through the molten liquid, this action absorbs impurities and carries them to the surface but the impurities are removed in another chamber.

This continues until pure liquid glass is created, ready to be shaped into test tubes and coffee pots.

For Borosilicate glass to be functional and durable for laboratory and kitchen use the raw material must be as clean as possible; many of these impurities are removed by chlorine gas to ensure high-quality heat-resistant glass.

Once this is accomplished, machines are used to shape the glass as it is inserted into molds and blasted with a stream of air above and below. This activity guarantees the glass achieves the proper strength.

When the glasses cool down, they are carefully scrutinized for rough edges or other anomalies.

If found wanting, they are put into another machine that runs them over more flames, and this heat will melt away any irregularities to make smooth edges.

In the case of Borosilicate cake dishes, the molten material is pressed down rather than being blown, while Borosilicate dishes are spun under a flame to seal any tiny holes or flatten any defects that may mar a flawless finish surface.

Thus, this amazing glass technology provides home and professional kitchens with sturdy cookware that is transparent and does not fracture when heated.


how to clean borosilicate glass

Here are four practical ways to clean your borosilicate glass:

  • The quickest and easiest method is to use a mild soap with a soft cloth or sponge, just like you wash your dirty normal dish, you simply scrub the glass using soap removing all residues and stains then rinse gently and thoroughly under water.
  • If the above method doesn’t work, then use a vinegar solution, especially for stubborn Borosilicate glass stains. How is this done? You simply dip your sponge or cloth into the solution and gently scrub the stained areas. The acidity of vinegar helps break down mineral deposits. Gently rinse the glass thoroughly to eliminate the vinegar smell.
  • The third method is to employ the use of baking soda paste for stubborn Borosilicate glass stains. You begin by making a paste using baking soda and water. Apply the paste to the affected areas and let it sit for 15-20 minutes. Scrub the glass gently with a non-abrasive sponge or brush. Rinse thoroughly to remove the baking soda residue.

  • The Fourth method is to use Isopropyl Alcohol for Oil or Grease stains: Dampen a cloth with isopropyl alcohol and gently wipe the affected areas. Ensure proper ventilation when using alcohol. This method is effective for removing fingerprints and other oily residues.
  • Lastly, in case all the 4 methods above fail, you might also want to consider using a commercial glass cleaner specifically designed for Borosilicate glass. This is done by simply following the manufacturer’s instructions carefully.

Finally, ensure you handle your Borosilicate glass with care and clean it regularly as this helps in maintaining its clarity and functionality.


Yes, Borosilicate glass is generally easy to clean. Its smooth surface makes it less prone to retaining residues, allowing for convenient cleaning.

Additionally, its durability allows for scrubbing or cleaning with various detergents without the risk of damage.


Yes, Borosilicate glass is dishwasher safe because its material is resistant to thermal shock, and can handle the hot water during washing and the subsequent cooling without shattering.

However, we recommend you check the manufacturer’s recommendation for easy cleaning of your Borosilicate glass because not every Borosilicate glass product might be suitable for a dishwasher some simply need hand washing.

Cleaning Borosilicate glass cups is a straightforward process. Here’s a step-by-step guide:

  • Place your Borosilicate glass cup under running water; this can remove any loose particles or residue.
  • Apply mild soap and use a soft sponge or cloth to wash off stains or residue on the body or inside the Borosilicate glass cup then rinse with water and allow to dry.
  • Thirdly, for Borosilicate glass cups that are designed with narrow areas, most manufacturers give you a soft brush to help with cleaning the hard-to-reach areas, the brush has a soft bristle that ensures your Borosilicate glass cup is thoroughly cleaned up especially the rim or the base.
  • As explained above, you can also use vinegar solutions for tough stains on your Borosilicate glass cup. You simply have to create a solution of equal parts water and white vinegar. Soak a sponge or cloth in the solution, and then gently scrub the stained areas. Rinse the cup well afterward.
  • Use a dry lint-free towel to dry the Borosilicate glass cup especially when it’s not used for heavy drinking or liquid.

We advise you to employ regular maintenance to prevent the buildup of dirt or stains, this ensures your Borosilicate glass cups are always in optimal and pristine condition.

By following these steps and exercising gentle care, you can maintain the clarity and cleanliness of your Borosilicate glass cups effectively.


How to Clean Glass utensils

You can clean glass utensils using a mixture of vinegar and water, soapy water, or a solution of baking soda and water.

Gentle scrubbing with a soft brush or sponge helps remove stubborn stains.

Ensure thorough rinsing to avoid residue.


Sterilizing Borosilicate glass is essential for certain applications, particularly in laboratories and medical settings.

See below for the 5 effective methods to sterilize Borosilicate glass:

 Autoclaving: This is the most common method, you simply place your glass items in an autoclave, and the work of the steam and high pressure helps to eliminate any viruses, bacteria, and other microorganisms that can’t be seen with the naked eye.

Boiling: After the Autoclaving method, another popular sterilization method is Boiling this is highly recommended for smaller-shaped Borosilicate glass items that can withstand heat, boiling them in water is a practical option.

Submerge the glass in boiling water for an adequate amount of time, typically around 10-30 minutes, depending on the size and nature of the items.

Dry Heat Sterilization:  As the name implies, this involves sterilizing your Borosilicate glass using dry heat, you simply place the glass in an oven and set it to a high temperature (typically around 160-180°C or 320-356°F)  for a specific duration but you have to ensure the glass surface reaches the required temperature for effective sterilization.

Chemical Sterilization: Chemical sterilization methods involve using sterilizing agents such as hydrogen peroxide gas or ethylene oxide.

Follow the manufacturer’s guidelines for concentration, exposure time, and aeration to ensure proper sterilization without residue.

UV-C Light Sterilization: Some Borosilicate glass items may be suitable for sterilization using ultraviolet (UV-C) light.

Expose the glass to UV-C light for the specified duration, following the guidelines provided by the UV sterilization equipment.

Always check the manufacturer’s recommendations for your specific Borosilicate glass items, as their resistance to heat and chemical sterilization methods may vary.

Additionally, ensure that the sterilization method chosen aligns with the intended use of the glass, considering factors like temperature sensitivity and potential damage.


While Borosilicate glass is more resistant to breakage than regular glass due to its thermal properties, it is not completely shatterproof.

It can still break if dropped from a significant height or if subjected to strong impact. The degree of resistance depends on the specific manufacturing process and thickness of the glass.


Borosilicate glass is designed to be resistant to thermal shock, which means it can withstand sudden temperature changes without breaking.

It is less prone to break when exposed to hot water than normal glass. For additional reading, see the distinction between Borosilicate glass and ordinary glass.

However, significant temperature fluctuations or fast shifts can still cause breaking, so treat it with caution.

Finally, see the video experiment comparing the behavior of Borosilicate and normal glass when hot water is poured into them.


While Borosilicate glass is relatively scratch-resistant, it can still be scratched by harder materials.

Common culprits include abrasive cleaning materials, sand, and certain metals.

Avoid using rough scouring pads or abrasive cleaners when cleaning Borosilicate glass to minimize the risk of scratches.

Additionally, storing it with items that may have abrasive surfaces can lead to scratches over time.
