How often should windows be cleaned?

By Shiny Fox Window Cleaning · Anstey, Leicester · Updated July 2026

For most homes, every 4 weeks is the sweet spot. It's frequent enough that dirt never takes hold, and it works out cheaper per visit than letting the glass go grubby between longer gaps.

Why 4 weeks works

Dirt on windows isn't just dust. It's traffic film (a greasy layer from road pollution), hard-water spotting, pollen, and — near trees or open country like the Charnwood Forest edge — sap and organic debris. Left 2–3 months, that mix bonds to the glass and takes real work to shift. Cleaned every 4 weeks, it never gets the chance.

• Consistent results: glass looks clean all month, not just the week after a visit.
• Cheaper per visit: quick maintenance cleans cost less than restoration cleans.
• Healthier frames: regular rinsing keeps uPVC frames and seals free of the grime that degrades them.

When a different schedule makes sense

• Every 8 weeks: sheltered homes away from main roads can stretch to 8-weekly — expect slightly more buildup per visit.
• More often: homes on busy routes (traffic film) or under mature trees (sap, birds) may want the full 4-weekly rhythm without ever skipping.
• One-offs: selling a house, end of tenancy, before a wedding or party — a single deep clean is the right call.

Does winter cleaning make sense?

Yes — arguably more than summer. Winter roads throw up the most grime, and low sun shows every smear. Pure-water cleaning works fine in cold and light rain; a professional round only pauses for ice or genuinely high winds. Skipping winter just means a harder, dirtier first clean in spring.
