How to Eliminate Condensation on Windows: The Simple Trick That Costs Less Than $1

This method works because salt — and basic mineral cat litter — naturally attracts moisture from the air. It acts like a mini dehumidifier for almost no cost.

Option 1: Using Coarse Salt (less than $1 per bag)

What to do:

1. Take a small bowl or container

2. Fill it with coarse salt

3. Place it on the windowsill or near the glass

4. Replace or stir the salt when it becomes wet or clumpy

Option 2: Using Mineral Cat Litter (about $0.90 per bag)

What to do:

1. Pour the litter into an old sock or breathable fabric bag

2. Close it with a rubber band

3. Place it on the windowsill

4. Replace it every 2–3 weeks

Why this works:

• Captures excess moisture from the air

• Creates a drier zone near the glass

• Reduces morning water droplets

• Helps prevent mold at the bottom of the window

It’s simple, invisible, cheap, and perfect for winter.
