FAQs

How often should I clean exterior windows?

Most homes benefit from cleaning exterior windows twice a year, but areas with heavy dust or pollen may need more frequent cleaning.

Can I use the same method on second-story windows?

Yes, but you will need an extension pole or a specialized hose-attachment cleaner for safety.

Why do my windows still streak after cleaning?

Streaks often occur when the cleaning solution dries too quickly. Clean during cooler parts of the day and use a squeegee for best results.
