Cleaning windows on rainy days seems, at first glance, like a contradiction in terms. Why do it if they're only going to get dirty again? However, in many cases, it's more useful and effective than you might think.

At La Corberana , we specialize in professional cleaning products for homes and businesses in Spain . We explain when and how to do it, and which products to use to achieve a flawless finish, even on rainy days.

Does it make sense to clean the windows when it rains?

Yes, but it depends on several factors. Although many people avoid it out of habit, cleaning windows on rainy days isn't a mistake if done correctly . In fact, it can be a good strategy when:

• The rain is light and does not carry mud or dust.

• The windows are very dirty and need cleaning urgently.

• They are cleaned from the inside or under roofs, awnings or eaves.

• Hydrophobic or anti-fog products are used to repel water.

The real problem isn't the rain, but the dirt already on the glass or the dirt carried in by the air. If the glass is treated with the right products, it can stay clean even after a light drizzle.

Advantages of cleaning windows on cloudy or rainy days

• There is no direct sunlight , so the product does not dry too quickly or leave marks.

• Ambient humidity helps to soften embedded dirt.

• If water-repellent products are applied, rain not only prevents dirt, but also keeps the windows cleaner for longer.

• It's a great time to clean protected interior or exterior windows, without having to wait for the "perfect day."

What products should you use to clean windows on rainy days?

The key is choosing the right products to prevent rainwater from leaving residue. At La Corberana , we recommend:

How to clean windows on rainy days: step by step

1. Choose the right moment

Avoid cleaning during heavy rain or strong winds. A light rain or cloudy day may be ideal.

2. Start from the inside

Clean the inside windows first. This way, you'll ensure at least one side is perfectly clean.

3. Use the right product

Spray the glass cleaner onto the glass or directly onto the cloth. Avoid using paper towels, as they tear easily and can leave residue.

4. Clean in an “S” shape

Make zigzag movements, from top to bottom, to cover the entire surface without going over clean areas.

5. Dry with a dry cloth

Using a second microfiber cloth, remove any remaining moisture. The finish will be more even and streak-free.

6. Apply a repellent treatment (optional)

If your windows are exposed to the outside, a repellent product can help keep them clean for longer.

When should you not clean your windows?

• During a rain with mud or dust in suspension.

• If there is a strong wind that could move dirt onto the freshly cleaned windows.

• On glass with traces of construction, paint, or adhesives that require another type of prior cleaning.

Additional tips for long-lasting cleaning

• Use warm or distilled water if you live in an area with very hard water.

• Avoid products containing ammonia if your window frames are made of painted aluminum.

• If the crystals are very exposed, apply a hydrophobic treatment once a month.

• Do not clean in direct sunlight: high temperatures cause the product to evaporate before it can work.
