The Best Way to Clean A Mirror
Mirrors make any room look bigger, brighter, and cleaner — but sometimes, after you clean them, they look cloudy instead of shiny.
If you’ve ever asked, “Why is my mirror cloudy after cleaning?”, you’re not alone. The problem usually isn’t the mirror — it’s your cleaning technique or your cleaning product.
Let’s look at the most common reasons why mirrors turn cloudy — and what really causes that dull, hazy look after cleaning.
1. Product Residue — The Hidden Film on Your Mirror
Many glass cleaners leave behind a thin film that dulls the shine. Dust, moisture, and residue build up over time, making the mirror look foggy.
If the mirror looks hazy even after cleaning, it’s probably leftover product sitting on the surface instead of evaporating.
2. Ammonia — The Hidden Enemy in Most Glass Cleaners
Most store-bought glass cleaners contain ammonia, which dries too quickly and leaves streaks or haze.
Besides the cloudy finish, ammonia can irritate your eyes, throat, and skin — especially in small bathrooms with poor ventilation.
This harsh ingredient is one of the biggest causes of that “foggy after cleaning” look that so many people notice.
3. Using Too Much Cleaner
When it comes to mirrors, less is more.
Using too much cleaner leaves extra moisture that takes longer to dry and often causes streaks or water marks.
If your mirror looks cloudy right after you wipe it, you probably used too much product.
4. The Motion Matters — Use the S-Pattern
ln the Speed Cleaning System, every step has a purpose — and how you move the cloth is just as important as what’s on it. The correct motion helps you clean faster and without streaks.
The right way:
-
Start dry: Before applying any cleaner, wipe the mirror with a dry microfiber or cotton cloth to remove dust or debris that could scratch the surface.
-
Spray a small amount of Blue Juice on your microfiber cloth — never directly on the mirror.
-
Always go top to bottom to keep dust and cleaner from falling onto areas you’ve already cleaned.
-
Move the cloth in a smooth S-pattern, starting at the top and gliding down in one continuous motion.
-
Avoid going back over what you’ve already cleaned — no backtrack.
-
End with a buff dry pass using a dry part of the cloth to make the mirror shine.
The S-pattern keeps your motion steady, reduces streaks, and saves time — that’s why every professional cleaner uses it.
5. Humidity and Water Spots
Bathrooms are full of moisture. Steam from showers and hard water can leave cloudy patches and spots that regular wiping won’t remove.
How to fix it:
-
After showers, wipe the mirror with a dry cloth or squeegee to remove moisture.
-
Keep a window open or use a fan to reduce humidity.
-
Deep clean weekly to prevent mineral buildup.
