What should be avoided when choosing a glass cleaning solution?

1. Solutions with ammonia for tinted glass

2. All types of glass cleaners

3. Water-based solutions for all surfaces

4. Natural solutions like lemon juice

The correct answer is: Solutions with ammonia for tinted glass

When selecting a glass cleaning solution, it is important to avoid solutions that contain ammonia, especially when cleaning tinted glass. Ammonia can damage the tint, leading to discoloration or degradation of the film over time. This is crucial to maintaining the quality and aesthetic of tinted surfaces, which can be particularly vulnerable to harsh chemicals. While some glass cleaners may be effective on clear surfaces, the chemical composition and potential reactions with court coatings found on tinted glass necessitate a more cautious approach. Solutions specifically formulated for tinted windows are usually recommended, as they are designed to clean without causing harm. In contrast, other options like water-based solutions may be appropriate for many surfaces and natural solutions, such as lemon juice, are often considered safe and environmentally friendly. It’s important to choose cleaning products that are compatible with the type of glass being cleaned to ensure longevity and optimal appearance.
