Window Cleaning in Prague: Complete Guide for Crystal Clear Windows Year-Round
Clean windows let in more light, improve mood, and give the entire apartment a fresh look. In Prague, where city dust, smog, and seasonal grime settle on windows, regular cleaning is especially important. Whether you live in a historic building with box-frame windows in Prague 1, a modern new-build in Karlín, or a panel flat on the outskirts, this guide will help you achieve crystal clear windows.
How Often to Wash Windows
Recommended frequency depends on location and window orientation. Windows facing busy streets get dirty faster. Generally: exterior panes 3–4 times yearly, interior panes twice yearly. In central Prague with higher pollution, we recommend exterior cleaning every 2–3 months.
Winter Window Cleaning — Is It Worth It?
Surprisingly, yes. In winter, windows are often dirtiest due to de-icing salt, condensation, and low-angled sun revealing every streak. Winter cleaning is possible above 0°C. At around 5°C, add antifreeze additive or isopropyl alcohol (100ml per litre). Professional winter window cleaning is the safest choice.
Professional Step-by-Step Process
1. Frame preparation: Always start with frames — wipe dust from grooves and sills.
2. Pre-washing: Apply solution with an applicator. Warm water with dish soap for regular dirt, vinegar solution for grease.
3. Squeegee: Pull top to bottom in smooth strokes, wipe rubber after each pass. Overlap by 1–2 cm.
4. Edge finishing: Microfibre cloth for edges and corners. Check at angle — streaks visible only against light.
Box-Frame Windows — A Prague Speciality
Historic Prague buildings commonly have box-frame windows with two rows of glass. Cleaning takes twice as long — you must open both wings, clean all 4 glass surfaces, and clean the space between them. Most common in Prague 2 (Vinohrady) and Letná.
