Crown glass has unique characteristics due to its historical manufacturing process, resulting in thin, uneven surfaces susceptible to damage. This type of glass, and lead cames in such windows, can be fragile due to their age and the materials used.

Cleaning Techniques

For cleaning leaded lights and crown glass, it is recommended to use a damp swab with a neutral non-ionic detergent in demineralised water, and to avoid scrapers or vigorous rubbing to prevent damage. Tools like scrim and squeegee rubber are unsuitable as they can catch on solder joints or damage came flanges.

Risks to Lead Cames

The stability of lead cames relies on a grey-white patina of lead carbonate, which protects the lead beneath. It is crucial to avoid acidic or alkaline cleaners (e.g. vinegar or ammonia-based cleaners) that can break down this protective surface.

Identifying Damage

When dealing with bowed panels, it's essential to check for jacking bars or support wires. Movement or daylight along seams indicates potential damage, requiring repair rather than cleaning.

Conservation Considerations

Routine cleaning in listed buildings doesn't require special permissions, but any repair efforts might. It is important to engage with conservators for major repairs and to adhere to heritage conservation guidelines.

Maintenance Recommendations

Historic windows benefitting from minimal intervention, like dry dusting or sporadic gentle wet cleaning, maintain structural integrity better. It's recommended to document the condition before cleaning and be conservative with cleaning frequency and techniques.

By employing careful techniques and using suitable materials, the integrity and appearance of leaded lights and crown glass in historical buildings can be preserved effectively.

Self-cleaning glass works based on two mechanisms within a thin titanium dioxide layer: a photocatalytic reaction driven by UV light that breaks down organic soiling, and a hydrophilic nature causing rainwater to sheet off the glass, carrying dirt away.

Risks of Using Blades

Using a blade on self-cleaning glass is risky. While a blade leaves no visible marks, it removes the self-cleaning coating. Similarly, abrasive pads, fine wire wool, and certain cleaning chemicals can damage this coating.

Cleaning Methods

To maintain the warranty and effectiveness of self-cleaning glass, only mild detergent in clean water or pure water with a water-fed pole should be used. Any use of silicon-based products, waxes or polishes, or strong alkaline removers can void the warranty.

Warranty Conditions

Warranty claims generally require documentation of compliance with the manufacturer's care guidance. This includes using appropriate cleaning methods and keeping records of the products used and their dilutions.

Environmental Considerations

The effectiveness of self-cleaning glass is limited by environmental factors like UV exposure and rain access. In London, north-facing or sheltered areas often do not perform well due to insufficient sunlight or rain, making them less effective at self-cleaning.

Installation Conditions

For newly installed self-cleaning glass to become active, it requires exposure to UV light, which may not occur immediately if the glass is covered or shielded during construction.

Recommendations

Finalizing a cleaning contract? Ensure it explicitly bans blades, abrasives, and unsuitable chemicals on self-cleaning glass. Report any cleaning challenges that arise, allowing the building manager to decide the approach.

The strategic management of self-cleaning glass, considering both environmental factors and maintenance protocols, is crucial to uphold functionality and warranty terms.

Debris can become embedded in the surface of toughened glass during production. When cleaned, these debris can scratch the glass, especially with the use of scrapers.

Causes of Scratches

When a scraper encounters fabricating debris, it can result in scratches, often identified by their curved, crescent shapes. These result from particles embedded in the glass detaching during the cleaning process.

Legal and Contractual Implications

Determining liability involves assessing whether the scraper or the pre-existing debris caused the scratch. Technical discussions often differentiate between manufacturing defects and cleaning negligence.

Insurance Considerations

Most insurance policies exclude coverage for property under the insured's control, necessitating a special treatment risk extension for potential damage claims caused by cleaning.

Contractual Best Practices

For commercial cleaning contracts, it is vital to include clauses that specify approved cleaning methods that are resilient to fabrication defects, and to maintain comprehensive documentation before and after cleaning.

Recommendations

Maintain thorough records of glass condition before cleaning, and agree on handling methods with building management to mitigate liability risks or disputes over damages.

Documenting glass conditions and using approved cleaning practices can significantly manage risk and potential liabilities related to glass cleaning.
