How to properly clean windows with film? This is the most common question asked by customers after installation. The answer is simple: caring for windows covered with protective, decorative or sun protection film does not require any special skills, but several key rules must be followed. Proper and regular care of the film on windows ensures that it retains its transparency, functionality and perfect appearance throughout its entire service life (up to 10–15 years).
By avoiding common mistakes, you protect your investment and ensure flawless performance of the coating.
Rule No. 1: Observe the “quarantine” period
The most important rule, which is often forgotten:
- Expectations: After installing any window film (armour, anti-graffiti, decorative), it is necessary to observe a 30-day “quarantine” period.
- Reason: This month, the residual moisture under the adhesive layer evaporates completely (polymerisation process). Until this point, the film is still “settling”.
- Prohibition: During these 30 days, it is strictly prohibited to wash, wipe or clean windows with film, as well as to wipe the edges of the coating. This may disrupt the adhesion process and lead to peeling at the edges or the formation of bubbles.
Rule No. 2: Choosing the right tools
When the waiting period is over, you can start cleaning. The main thing is to use soft, non-abrasive materials.
- Permitted: Soft sponges, microfibre cloths, clean towels or rubber scrapers (squeegees) designed for windows.
- Prohibited: Hard brushes, abrasive sponges, steel scrubbing pads, or any tools that may scratch the surface. Remember that protecting the film from scratches depends on proper care.
Rule No. 3: Choosing detergents
The type of cleaning agent is critically important, as some chemicals can damage the polymer structure of the film.
- Permitted: Plain clean water (preferably distilled) or a mild soap solution (use mild liquid soap or baby shampoo). Specialised window film cleaning products may also be used.
- It is strictly forbidden to:
- Ammonia and solvents: Ammonia-based products (most household glass cleaners) can destroy the adhesive layer and cause clouding.
- Abrasive powders: Any cleaning products containing fine particles may leave micro-scratches.
Step-by-step guide to cleaning
The cleaning process is as simple as possible if you follow these steps:
- Dust removal: First, spray the window generously with water (or a mild solution) to wash away dust and dirt particles. Do not rub the dry surface.
- Applying the solution: Apply the cleaning solution to a sponge or microfibre cloth and gently wipe the entire surface without applying excessive pressure.
- Removing moisture: Use a soft rubber scraper (squeegee) or a clean soft cloth to remove moisture. Move from top to bottom in smooth, overlapping strokes.
- Drying: Wipe the edges and corners with a dry soft cloth to prevent water accumulation.
By following these simple rules, your window film in Estonia will retain its original appearance. As installation experts, we guarantee the quality of the film, and by following this guide, you guarantee its durability.
🔥 Expert advice: Pay attention to the edges
The edges of the film are the most vulnerable area. When washing, avoid directing water jets or applying strong pressure to the joints. If you notice that the edge is starting to peel off during cleaning, contact specialists immediately for repair.
Frequently Asked Questions
