When you’re ready to transition from wiping glass with old rags and off-the-shelf sprays to achieving the clean, streak-free results only a professional can deliver, it’s time to invest in a purpose-built window cleaning starter kit. While ready-made kits like the Ettore Welcome Kit or the Pro Window Cleaner Starter Kit available from Detroit Sponge offer excellent value and a comprehensive collection of tools, many seasoned pros prefer to customize their arsenal. Building your own starter kit ensures every piece of equipment from your squeegee channel to your chemical solution is perfectly matched to your specific cleaning style, the type of windows you service, and the demands of your unique business.
This guide will walk you through the five core categories of professional window cleaning supplies, helping you select the best components from industry-leading brands like Ettore, Unger, Moerman, and Pulex, so you can build your own window cleaning starter kit that maximizes your efficiency and delivers pristine results on every job.
The Foundation: Your Squeegee, Washer, and Rubber
The core of any traditional window cleaning setup is the dynamic duo: the squeegee and the washer, also known as the scrubber or T-bar. Investing in high-quality professional-grade tools here is non-negotiable, as these are your primary streak-fighting implements.
The Professional Squeegee
A professional squeegee is composed of three parts: the handle, the channel, and the rubber blade.
- Handle: This is your grip. Look for an ergonomic handle, such as the Unger ErgoTec, to reduce hand and wrist fatigue during long cleaning sessions. Many handles feature a quick-release mechanism that allows you to swap channels on the fly, saving valuable time.
- Channel: The metal or plastic part that holds the rubber blade. Ettore’s Master Brass Squeegee and Unger’s Pro Stainless Steel Squeegee are popular choices known for their durability and quality. You should select a variety of sizes:
- 6- to 10-inch channels are ideal for French panes, transoms, and detailing small windows.
- 12- to 18-inch channels are the most versatile size for standard residential and storefront windows.
- 20-inch channels and larger are used for maximum efficiency on large picture windows or commercial storefronts.
- Rubber Blade: The most critical component for a streak-free finish. Professional rubber (such as Ettore Master Squeegee Rubber) is designed to be replaced frequently and can be purchased in long tubes and cut to fit your channels. You should keep multiple replacement blades on hand, ready to swap them out as soon as a nick or tear appears.
The Washer (Scrubber)
The washer, or stripwasher, is essential for applying your solution and agitating dirt before the squeegee wipe. It consists of a T-bar handle and a fabric sleeve. Microfiber sleeves are highly recommended because they hold a large amount of water and possess excellent cleaning power without scratching the glass. Brands like Ettore and Moerman offer excellent complete washers that are designed for durability and superior cleaning.
The Essential Trio: Buckets, Solution, and Towels
While the squeegee is the star, the supporting cast ensures a smooth, non-stop performance. These items manage your cleaning fluid and perfect the final detailing.
The Right Bucket
Forget the standard round household bucket. Professional window cleaning requires a sturdy, rectangular, high-capacity bucket (typically 5 or 6 gallons) that is wide enough to fit the full length of your largest T-bar washer (18 inches or more). A rectangular shape is less likely to tip over than a round one and is often easier to carry. You can even add Bucket Casters to increase mobility on the job.
Professional Cleaning Solution
Professional window cleaners rarely use harsh chemicals. Instead, they rely on concentrated, specialized soaps that provide "slip" to the squeegee and help the blade glide effortlessly across the glass to prevent skipping and streaking.
- Concentrates: Products like Dazzle-100 or other high-concentrated soaps are the choice of many pros. They are highly effective at breaking down grease and grime.
- DIY Option: A small amount of mild dish soap (like Dawn) mixed with water is a cost-effective alternative for general use, but professional concentrates offer superior performance and glide.
Detailing Towels
Towels are critical for cleaning up water runoff, drying sills, and detailing the edges of the glass that the squeegee can’t reach. To achieve a true streak-free finish, you need lint-free, highly absorbent material.
- Microfiber Cloths: These are the window washer's secret weapon. They are highly absorbent, soft on glass, and do not leave lint behind.
- Huck Towels: Recycled surgical towels (often blue) are another professional favorite, known for their high absorbency and ability to detail edges without leaving fuzz. Keep a separate, dry towel in your belt for wiping your squeegee blade between pulls.
Addressing the Tough Stuff: Scrapers and Specialized Gear
Windows often come with more than just dust and dirt. Paint overspray, bird droppings, hardened sap, and construction residue require specialized tools to remove safely without scratching the glass.
Scrapers
A high-quality scraper is a mandatory component of your starter kit. They come in various sizes, from small pocket scrapers like the Unger ErgoTec Safety Scraper for quick, on-belt access, to larger ones for pole work.
Safety Note: Always use a new, sharp blade and wet the glass thoroughly before scraping. Never use a scraper on tempered glass, as it risks scratching the surface.
Carrying Your Gear (BOAB)
Efficiency is everything in professional window cleaning, and nothing saves more time than keeping your tools within reach. A Bucket on a Belt (BOAB), such as the Ettore SideKick, attaches directly to your tool belt or pants and holds your squeegee and washer between windows. This eliminates constant bending over to dip tools into your bucket on the ground, dramatically increasing your speed and reducing strain.
Extending Your Reach: Poles and High-Access Tools
Once you move beyond ground-level windows, your kit must expand to include high-reach equipment. A telescoping extension pole allows you to safely and efficiently clean second-story windows while keeping your feet firmly on the ground, minimizing the need for ladders.
Extension Poles
Look for poles made from lightweight, durable materials with reliable locking mechanisms.
- Materials: Aluminum poles are a popular, lighter choice for standard use, while carbon fiber poles offer superior rigidity at greater lengths, making them the premium choice for higher-up work.
- Systems: Brands like Ettore feature patented locking systems (like the Click-lock) on their REA-C-H Extension Poles that ensure your squeegee and washer are securely attached at any height. Poles are available in various lengths, from short 4-foot models to telescoping poles that reach 30 feet or more.
Considering Water-Fed Poles (WFP)
While a traditional starter kit focuses on the squeegee method, professionals looking to scale up often incorporate a Water-Fed Pole system. These systems use de-ionized (purified) water, which is pumped up a long pole to a specialized brush. Because the water contains no minerals, it dries spot-free without squeegeeing. This is a larger initial investment but is the ultimate tool for high, hard-to-reach commercial windows and significantly boosts productivity.
Building for Your Niche: Residential vs. Commercial
The final step in building your perfect kit is tailoring it to your primary clientele.
- Residential Focus: Your kit should emphasize versatility and detailing. Include a wide array of smaller channels (6", 8", 12") for French panes and divided windows. Stock up on microfiber cloths for meticulous detailing and be sure to have a track brush for cleaning window sills and tracks, which homeowners often inspect closely.
- Commercial/Storefront Focus: Efficiency is key. Prioritize larger squeegee channels (18" and 22") for maximum coverage and use a quick-release handle to move fast. Invest in a heavy-duty scraper and consider high-performance equipment like the Unger SpeedClean Indoor Window Cleaning Starter Kit or the Pulex Techno Duo for high-volume, quick-turn jobs.
Maximizing Your Efficiency and Investment
As you look at all the available options, remember that the goal of building your own professional-grade starter kit is not just to clean windows; it’s to clean them faster, better, and with more consistent results than your competitors. By selecting the highest quality components from trusted brands, you are investing in tools engineered to withstand daily professional use. High-quality equipment requires less force, reduces fatigue, and ensures a superior, streak-free finish that saves you time and leads to higher customer satisfaction, making the investment well worth it in the long run. Take the time to choose your components wisely, and you will set the stage for a thriving window cleaning business.
Frequently Asked Questions About Window Cleaning Kits
What is the ideal combination of soft and hard squeegee rubber to have on hand?
Professional squeegee rubber comes in both soft and hard varieties. Soft rubber is generally recommended for colder temperatures and is more flexible, making it ideal for cleaning uneven or curved glass surfaces without leaving streaks. Hard rubber is better suited for warmer climates, as it holds its shape better in the heat and provides a straighter, cleaner edge for large, flat windows. For a starter kit, having both on hand (or a versatile high-quality medium-grade rubber) ensures you are prepared for varied weather conditions and different types of glass.
How do I maintain and store my squeegee to extend its life?
The key to extending the life of your squeegee is proper care of the rubber blade. Always wipe the rubber clean with a dry, lint-free towel between uses, ensuring no dirt or grit is trapped underneath the blade. When storing, ensure the blade is protected and nothing touches the edge, as a tiny nick can cause a persistent streak that ruins a job. You can also reverse the blade in the channel to utilize the opposite, sharp edge, effectively doubling its lifespan before needing a full replacement.
