How to Clean Exterior Windows with Your Krystal Klear Cloth

(And Why It’s Worth the Extra Effort)

Your outside windows are exposed to all kinds of dirt, pollen, and pollutants—so they often need a bit of special care, especially at the start of each season or when using your Krystal Klear Cloth for the first time.

But don’t worry—once you do this deep clean, your windows will stay cleaner longer and be much easier to maintain.

These tips also work beautifully for interior windows, stainless steel, and granite that have been treated with chemical cleaners or polishes in the past.

🌿 Why Exterior Windows Need a Different Approach

Exterior windows collect everything: sticky pollens, pollution, and grime you can’t even see. That first deep clean may require a little elbow grease, but it’s worth it.

Once you get that film off, your regular wipe-downs with just water and your Krystal Klear Cloth will be fast and effortless—and your windows will stay cleaner longer.

🧼 Step-by-Step: First-Time or Seasonal Deep Clean

1. Prep with Warm Water + a Drop of Dish Soap

Use warm water and just 1–2 drops of dish soap (more isn't better—it’ll just make rinsing harder).

2. Wipe Off the Heavy Grime

Use your Krystal Klear Cloth or any older cleaning rag to remove the surface dirt. If there's a thick film or you're concerned about staining your good cloth, use one of our Multi-Surface Cloths first.

3. Switch to Your Krystal Klear Cloth

Once the heavy soil is gone, switch back to your Original Krystal Klear Cloth for the finishing clean.

4. Rinse with Clean Water

No need to use a second product—just rinse your cloth well and wipe with fresh water.
Tip: Wring your cloth out well for the final wipe; it should be just damp for the best streak-free result.

💧 Regular Maintenance Made Easy

Once the first clean is done, you can use just water and your cloth for touch-ups all season long. Dog nose smudges, fingerprints, and pollen? Gone in seconds—no streaks, no splotches.

🧺 Keep Outside Cloths Separate

We recommend keeping cloths used on outside windows separate from those used inside your home. Here’s why:

The thousands of micro-split fibers that polish your surfaces so beautifully are also great at trapping stains.
While stains don’t affect performance, we know some customers prefer their cloths to look clean, too.
Keep a set of “outdoor” cloths and another for glass, mirrors, chrome, stainless steel, and granite inside your home.

🚫 A Note About Bleach

While bleach can help with stains, we don’t recommend it. It won’t harm your cloth’s cleaning ability—but it may shorten the cloth’s lifespan.

Instead, skip the bleach and separate your cloths. You’ll protect your investment and avoid adding toxic chemicals back into your home.
