Impress your landlord or letting agent with spotless windows ✨
Avoid deductions from your deposit with a proper glass clean 🧽
Say goodbye to streaks, dust, and greasy marks ✋
Complete your end-of-tenancy checklist with sparkling results 🏡
Whether you’re leaving a studio flat or a large rental house, cleaning the windows is often one of the most overlooked tasks. But when it comes to end-of-tenancy inspections, even the smallest streak or smudge can be flagged. Clean, sparkling windows help your entire home look brighter and more cared for—making a strong final impression on landlords or estate agents.
In this guide, we’ll show you how to clean your windows properly before moving out, using simple methods that make a noticeable difference and could help secure your full deposit.
Understand What Landlords Look For During Inspections 🧐
When it comes to window cleaning, it’s not just the glass that matters. Frames, sills, tracks, and seals are all checked for dust, mould, or water damage. If you’re leaving these areas untouched, your efforts could fall short during the final walk-through.
Most landlords follow detailed checklists (like this letting inspection guide by Propertymark), and windows are usually near the top. Take your time and clean every part thoroughly.
Use a Simple Solution for a Streak-Free Finish 🧼
You don’t need fancy cleaners or strong chemicals. A tried-and-tested mix of warm water, white vinegar, and a drop of washing-up liquid works wonders. Spray it onto the glass and wipe in circular motions using a microfibre cloth.
Once done, dry the glass with a rubber squeegee or dry cloth to avoid streaks. Never use paper towels or tissues—they leave fibres behind and may dull the shine.
For large windows, or if you’re short on time, book a professional window clean with London Window Cleaning. We’ll make sure everything’s spotless from top to bottom.
Clean the Frames, Handles and Window Tracks 🧹
It’s easy to forget about the edges, but dirt and dust often build up around the frames and inside the tracks. Use a toothbrush or a narrow brush to loosen debris, then vacuum it out before wiping clean.
Plastic frames can be wiped down with soapy water, while wooden ones may need a specialist product to avoid damage. Pay attention to handles, too—they often show fingerprints and grime.
If you’re doing a full end-of-tenancy clean, the team at End of Tenancy Cleaning London can help with carpets, ovens, and bathrooms, while you handle the finishing touch on the windows.
Check for Mould or Condensation Marks 🌧️
London homes often suffer from window condensation and black mould, especially in winter. If you spot any dark patches on seals or sills, use a solution of white vinegar or a mould remover to scrub them away.
Remember to wear gloves and ventilate the area well. Don’t forget to dry the frame thoroughly—moisture left behind can encourage mould to return.

Polish the Glass for a Flawless Shine ✨
Once everything is clean and dry, buff the glass with a dry microfibre cloth to remove any leftover smears. For extra sparkle, a small spray of glass polish and a quick circular buff will give it that professional finish.
Tip: Clean your windows on a cloudy day. Sunshine dries the solution too quickly, often leaving streaks behind. And don’t forget the inside and outside of the windows for the best result.

Don’t Forget the Window Dressings 🧵
Blinds and curtains can gather dust and affect how clean your windows look overall. Use a vacuum brush attachment to clean blinds, and take down washable curtains for a quick cycle.
To go the extra mile, use professional curtain cleaning services from reliable partners like Charles Carpet Cleaning, especially if your property came furnished.
Well-maintained window dressings complete the clean and show that you’ve looked after the property properly.
