Introduction

Washing outdoor windows can be a tedious and time-consuming chore. Unlike indoor windows, outdoor windows are exposed to the elements like rain, dirt, pollutants, and UV rays. Over time, this can cause outdoor windows to become extremely dirty and stained. However, with the right tools and technique, you can get your outdoor windows looking sparkling clean.

In this comprehensive guide, we will walk you through all the steps and best practices for washing outdoor windows. We will cover everything from assembling the necessary supplies, prepping the windows, washing and drying techniques, and finishing touches. With our tips, you’ll be able to achieve streak-free, crystal clear outdoor windows.

Gather the Right Supplies

The first step in effectively washing outdoor windows is gathering the proper supplies. This will make the process faster and allow you to properly clean the windows. Here are the recommended supplies:

A window washing wand or pole – This allows you to reach and clean second story or high windows safely from the ground. Look for one with a curved head to fit the window contour.
Soft microfiber cloths and towels – Microfiber glides smoothly on glass and absorbs water and soap residue. Avoid paper towels.
Mild dish soap or specialty glass cleaner – Use a small amount of a gentle cleaner like blue Dawn dish soap. Avoid harsh chemicals.
Bucket – Use for holding the wash water. Get one with a long handle for easy carrying.
Squeegee – After washing, use a squeegee to scrape water off in a smooth, even motion.
Scrub brush – A soft brush helps agitate dirt and debris. Choose one with a long handle.
Sponge – Useful for scrubbing tougher spots. Get an abrasive sponge to tackle stuck-on grime.
Ladder – Safely reach second story or tall windows. Use a sturdy, multi-position ladder.
Garden hose – This provides the wash water. Make sure it reaches all areas.
Drop cloths – Protect plants and surfaces from excess water and cleaner.

Prep the Window Surface

Before washing, you need to prep the windows to loosen debris and ensure cleaning efficiency. Follow these pre-wash steps:

Sweep or wipe off loose dirt and cobwebs using a dry towel or soft brush. This prevents smearing.
Spray windows gently with the hose. Let water soak glass for 2-3 minutes to soften stuck-on debris.
Mix your cleaning solution. For standard dirt, mix 1-2 tbsp dish soap per gallon of water. For heavy grime, make a stronger mixture.
Fill your wash bucket half full and add the cleaning mixture. Soak microfiber cloths in the solution.
Lay drop cloths below the windows and on nearby plants/furniture. This contains the wash water.

Wash Windows from Top to Bottom

With your supplies gathered and the window prepped, it’s time to wash. Follow these steps for cleaning outdoor windows:

Wash the Exterior

Use the wand or pole to reach top areas without a ladder. Add the microfiber cover.
Starting at the top, use a side-to-side motion to clean. Apply light pressure.
Scrub glass using circular motions to remove stuck-on debris. Adjust pressure as needed.
When washing lower levels, spray cleaning solution directly on the glass to reactivate.
Rinse thoroughly with fresh water using pole attachment or garden hose. Eliminate soap residue.
Use the microfiber cloth to wipe standing water and drips after rinsing.

Wash the Interior

Step inside and close windows to wash interior glass surface.
Use the brush attachment on your wand/pole to scrub interior. Add additional cleaner if needed.
Wipe away excess water with your microfiber cloth. Take care not to streak glass.
For windows you can reach, spray cleaner directly on the glass and use a sponge in circular motions.
Rinse thoroughly with clean water, then wipe with microfiber towel to prevent water spots.

Dry and Finish the Windows

Drying is one of the most important steps for crystal clear, streak-free windows. Here’s how to properly dry outdoor windows:

Use a squeegee starting at the top corner. Glide down using firm, even pressure. Overlap slightly.
Wipe the squeegee blade frequently so it doesn’t spread dirty water.
Go top to bottom in straight, slightly overlapped lines. Pay attention to the edges.
Avoid excess pressure which can push water droplets under the blade. Keep the blade lightly pressed.
For the bottom edge, wipe any remaining moisture with your microfiber cloth.
Use the microfiber towel to buff the window and remove any water spots.
Check the exterior in sunlight and touch up any visible streaks with towel and squeegee.
Repeat wash and dry cycle for extremely dirty windows to ensure they are pristine.

Tips for Washing Outdoor Windows

Follow these additional tips and best practices when tackling dirty outdoor windows:

Wash windows on a cloudy day when the sun won’t dry the glass too quickly. Avoid direct sun.
Know when to replace your squeegee blade. Worn blades will leave streaks. Change the blade every 3-4 months.
Go for quality when choosing window washing tools. Your wand, squeegee, and cloths should glide smoothly without catching.
Wash windows early in the morning before it gets too hot. Heat causes cleaning solution and water to dry too fast.
Use warm or hot water for extra cleaning power. Hot water is great for dissolving oil and grime.
Never mix different cleaners like ammonia and bleach. Stick to mild dish soap or vinegar solutions.
Wipe down window frames and sills after washing the glass. Use a soft brush and mild cleaner.
Rinse your microfiber cloth and squeegee blade frequently for best results. Dirty tools leave smudges.
Wear soft gloves to protect your hands from harsh cleaners. Cushioned gloves also improve your grip.
Move slowly and methodically. Don’t rush the wash and dry stages. Patience prevents streaking.

How to Wash Different Types of Outdoor Windows

Certain outdoor window types require adjusted techniques:

Vinyl Windows

Vinyl windows are prone to scratching and water spots. When washing:

Use extra soft microfiber cloths and pole covers. Avoid abrasive sponges.
Rinse thoroughly with clean water and dry completely to prevent spots.
Rub gently when scrubbing. Check cloths for buttons, nails, or objects that could scratch.
Use rubbing alcohol or vinegar to remove stubborn spots. Avoid harsh cleaners.

Wood Windows

For stained or painted wood windows, take precautions to avoid damage:

Test cleaner on a small spot first to prevent stripping the finish.
Use soft microfiber and a delicate touch when scrubbing wood sections.
Wipe wood trim and frames with a damp cloth. Don’t immerse in wash water.
Avoid excessive water. Rinse and dry wood thoroughly after washing.
Rub stained wood along the grain. Never scrub across the grain.

Skylights

Follow these tips for washing hard-to-reach skylights:

Use a telescoping pole specifically designed for skylights to wash safely. Do not step on the glass.
Fill the skylight curb with an inch of water before washing to catch drips.
Start washing at the top edge using overlapping side-to-side strokes.
Dry skylights starting at the bottom edge to avoid drips running down clean areas. Wipe excess water as you go.

Multi-Story Windows

Cleaning tall second story windows presents challenges:

Use a multi-position ladder at different heights and angles to access the entire window safely.
Opt for a window washing wand with an extended pole to easily reach upper windows from the ground.
Have someone monitor the ladder while you work to ensure stability and prevent falls.
Take your time. Don’t overextend or lean too far from the ladder. Move the ladder as needed.

When to Call a Professional

While DIY washing works for many standard outdoor windows, some situations call for a professional:

Windows over 2 stories high. Professional pole systems can reach tricky heights.
Severely neglected windows with years of built-up grime or damage. Professionals have expertise and equipment to handle.
Windows requiring chemical cleaners, sealants, or anti-corrosion coatings. Improper use of chemicals can damage windows.
Windows in risky, difficult to access locations. Professionals can safely tackle them.
Post-construction cleanup of new windows and new homes. Remove debris, stickers, stains.
Window areas with safety hazards like electrical lines or roof access issues. Let the pros safely handle.
Historically designated or antique windows. Specialized restoration skills may be needed.
Unusual window types like domes or triangles. Unique tools and methods may be required.
