Can you change glass from hydrophobic to hydrophilic?

In summary, using a bronze wool cloth to rub over glass surfaces can change them from hydrophobic to hydrophilic, allowing for a more effective and efficient cleaning process.

Hi, I run a window cleaning business and a free window cleaning magazine.

As you will probably know window cleaners tend to use the properties of pure water and a water fed pole system in order to clean glass.

Technique is important to a perfect finish so hydrophilic glass is our friend since water sheets down the glass and aids a perfect clean as you are able to rinse well.

Hyrophobic glass is our enemy, because water beads on the glass and a perfcet clean and rinse off is difficult. In fact some window cleaners result to squeegeeing the water of to prevent 'spotting'.

I wanted to know if there was any truth into an experiment carried out by a window cleaning company in Ohio.

By accident they discovered that they were able to change how the glass surface works, changing it from hydrophobic to hydrophilic by simply rubbing over the glass with a bronze wool cloth.

Is the bronze wool adding any scientific advantage or could this process be replicated with any cloth since hydrophobic is usually oils etc on the glass??

The answer is yes, the bronze wool cloth adds a scientific advantage that can't be replicated with any other cloth. The bronze wool is specially designed to remove dirt, dust, and oils from glass surfaces, allowing them to become hydrophilic and allowing water to sheet down the glass for better cleaning results. This process works because the bronze wool cloth is slightly abrasive, which helps to scrub off the oils and dirt that make the glass surface hydrophobic.
 

FAQ: Can you change glass from hydrophobic to hydrophilic?

What is the difference between hydrophobic and hydrophilic glass?

Hydrophobic glass is treated with a coating that repels water and other liquids, causing them to form droplets and slide off the surface. On the other hand, hydrophilic glass is treated with a coating that attracts water and allows it to spread evenly, creating a thin film on the surface.

How is hydrophobic glass made?

Hydrophobic glass is typically made by coating the surface of the glass with a thin layer of a hydrophobic material such as a fluoropolymer or silicone. This coating is then cured or bonded to the glass using heat or UV light to create a water-repelling surface.

Can you change glass from hydrophobic to hydrophilic?

Yes, it is possible to change glass from hydrophobic to hydrophilic by removing the existing hydrophobic coating and replacing it with a hydrophilic one. This can be done by using a strong solvent or by physically removing the coating through abrasion or etching.

What are the benefits of hydrophobic glass?

Hydrophobic glass has many benefits, including easier cleaning, reduced water spotting and streaking, and improved visibility in rainy or wet conditions. It also helps to prevent the buildup of mold, mildew, and other contaminants on the surface of the glass.

Is hydrophobic glass suitable for all types of glass?

No, hydrophobic glass is typically only suitable for smooth, non-porous surfaces such as glass. It may not be effective on rough or textured surfaces, and it may not adhere properly to certain types of glass, such as tempered or laminated glass.
