An Introduction to Traditional Window Cleaning

Traditional window cleaning remains one of the most effective ways to achieve a streak-free shine on glass. This method is trusted by professional window cleaners and DIY users because it offers precision, control and reliable results. If you want to understand traditional window cleaning, the tools required and how to use them, this guide covers the essentials.

How Traditional Window Cleaning Works

The traditional window cleaning process uses a combination of soapy water, an applicator, a scraper and a squeegee to remove dirt and leave clean glass.

1. Apply cleaning solution using an applicator or washer sleeve.

2. Loosen and remove stubborn dirt with a scraper while the window remains wet.

3. Squeegee the water off in smooth, overlapping strokes for streak-free results.

4. Detail the edges, frames and sills with sill cloths, microfibre cloths or scrims.

5. Polish the glass to finish the traditional window cleaning method.

This method is perfect for shop fronts, interior glass, residential windows and anywhere you need accuracy and consistent performance.

Chemicals Used in Traditional Window Cleaning

Traditional window cleaning requires a good window cleaning soap or detergent designed to cut through grime and help the squeegee glide smoothly.

• Professional window cleaning detergents prevent streaks and are gentle on the skin.

• Many window cleaners add extra soap to increase glide, making the squeegee faster and easier to control.

• Specialist formulas are available for PVC frames, tough stains and detailed traditional cleaning work.

What Is an Applicator (Washer)?

An applicator - also known as a washer - is a key tool in traditional window cleaning equipment. It consists of a T-bar and a removable sleeve that holds water and detergent. We do sell them also as complete ones here.

Types of washer sleeves:

• Standard Sleeves: Blended fibres, lightweight and easy to use.

• Part-Microfibre Sleeves: Hold more water and improve dirt pickup.

• Microfibre Sleeves: Highly absorbent and excellent for dirty glass.

• Heavy-Duty Sleeves: Include abrasive fibres for scrubbing stubborn marks.

Types of T-Bars:

• Standard T-Bars: Lightweight and affordable.

• Ergonomic T-Bars: Extra grip for comfortable professional use.

• Aluminium T-Bars: Rigid, durable and ideal for frequent cleaners.

• Swivel T-Bars: Angle-adjustable for difficult corners or pole work.

  What Is a Scraper?

  A scraper is a specialised tool with a sharp metal blade designed to remove stubborn dirt and debris during traditional window cleaning. While the applicator and squeegee handle most cleaning tasks, the scraper is essential for tackling anything stuck firmly to the glass. Used correctly, a scraper prevents damage by removing contaminants before they interfere with the squeegee.

  What Scrapers Are Used For

  Scrapers are ideal for removing:

  • Paint splashes, plaster and silicone residue

  • Dried bird mess and insect marks

  • Sticky labels and adhesive residue

  • Tree sap and mineral spots

  • Baked-on dirt that cannot be removed with detergent alone

  Types of Scrapers

  Mini / Pocket Scrapers

  • Compact design, usually with a retractable blade

  • Perfect for quick touch-ups or small stubborn marks

  • Easily stored in a pocket or pouch

  4", 5" and 6" Scrapers

  • Larger T-bar style scrapers for fast, controlled scraping

  • Suitable for bigger panes of glass or heavier deposits

  • Often come with blade covers for safe storage

  Long-Handled Scrapers

  • Provide extra reach and leverage

  • Helpful for shop fronts, tall windows or deep-set frames

  • Typically used for heavy-duty tasks and professional work

  Important Safety Note

  Always ensure the glass is wet before scraping. Scraping dry glass increases the risk of scratching, even with the best tools. Use clean, sharp blades and replace them regularly to avoid chipping or dragging.

  What Is a Squeegee?

  The squeegee is the core tool of traditional window cleaning. It removes dirty water from the glass, leaving a clean, streak-free finish. A good squeegee improves speed, precision and overall quality, which is why professionals often invest in high-quality handles, channels and rubbers. We do sell complete ones here.

  Scrims, Microfibre Cloths & Chamois

  Cloths are essential for detailing, drying and polishing during traditional window cleaning. Each type has its own purpose and performs differently depending on the finish you want.

  ---

  Scrims (Linen)

  Scrims are traditional window-cleaning cloths made from high-quality linen. They are well-known for their durability, absorbency and ability to polish glass to a professional shine.

  Key features of linen scrims:

  • Made from pure linen, which becomes more absorbent the more it is washed

  • Excellent for detail wiping, edge drying and polishing

  • Very long-lasting when properly maintained

  • Need "breaking in" - usually several washes before optimal use

  • May release slight lint when old, worn or not washed correctly

  Scrims are particularly popular among traditional cleaners because linen fibres naturally tighten and soften with repeated use, improving their performance over time.

  Microfibre Cloths

  Microfibre cloths are now extremely popular due to their absorbency and lint-free finish.

  • Smooth microfibre: Best for final polishing

  • Textured microfibre: Best for general wiping and detailing

  Care Tip:

  Avoid bleach or fabric softener when washing microfibre - it damages the fibres and reduces absorbency.

  Chamois Leather (Shammy)

  A chamois leather is another traditional polishing cloth used by professional window cleaners. Made from natural or synthetic leather, the chamois is prized for its softness and ability to leave a spotless finish.

  Why window cleaners use chamois:

  • Exceptionally soft and gentle on glass

  • Leaves a smooth, smear-free polished finish

  • Absorbs water quickly without leaving fibres behind

  • Works well for final detailing, especially on interior glass

  • Ideal for automotive glass and mirrors too

  Care Tip:Always keep a chamois slightly damp when polishing - a fully dry chamois can drag or stick on the glass. After use, rinse with clean water and allow it to dry naturally (never on a radiator).

  Using a Telescopic Pole

  A telescopic pole allows you to perform traditional window cleaning at height without ladders, making the job safer and more efficient.

  Why Use a Telescopic Pole?

  • Clean high windows from the ground

  • Reach over obstacles like signs, shop displays or conservatory roofs

  • Maintain precise control when paired with swivel squeegee handles

  Choosing the Right Pole

  Most tool brands design poles to match their own handles, T-bars and attachments. Using the same brand ensures:

  • Secure fit

  • Smooth operation

  • Reliable locking mechanisms

  Poles come in a range of lengths and materials, including aluminium and lightweight carbon fibre, ideal for frequent professional use.
