Here are some tips to help you take care of your windows, screens, and exteriors while adapting to the local climate, as well as advice on when to call in the professionals.

Window cleaning and maintenance
DIY Cleaning
Windows in Central Maui take a beating from the salty air and tropical rains. Cleaning windows both inside and out not only helps to maintain a pristine appearance but also protects the glass from etching and damage caused by salt and mineral deposits.
Frequency
Clean exterior windows every 2-3 months and interior windows every 4-6 months. Homes closer to the coast may need more frequent cleanings to address the salt buildup.
How to Clean
Start by rinsing the windows with water to remove loose dirt and salt. Use a mild detergent or a mixture of vinegar and water for streak-free cleaning. Avoid abrasive materials, as they can scratch the glass.
Pro Tip
Consider investing in water-repellent glass treatments for windows, which can help reduce future salt and grime buildup.
Professional Cleaning
Professionals have the right tools and techniques to prevent streaks and protect your windows from long-term damage caused by the elements.
Frequency for professional
For residential properties, consider professional window cleaning once or twice a year. For commercial properties or coastal homes with heavy salt exposure, quarterly cleanings might be necessary.

Maintaining and Cleaning Screens
DIY Cleaning
Screens are essential for keeping bugs out while allowing the tropical breezes in, but they also collect dirt, pollen, and salt. Regular maintenance ensures your screens remain functional and clean.
Frequency
Clean window screens every 3-4 months.
How to Clean
Remove the screens and use a soft brush to gently scrub them with soapy water. Rinse thoroughly with a garden hose and let them dry completely before reattaching.
Pro Tip
For stubborn grime, add a bit of vinegar to the soapy water. Always handle screens carefully to avoid bending or tearing.
Professional Cleaning
If screens are particularly dirty or have been exposed to heavy winds and storms, professional deep cleaning might be necessary.
Frequency for Professionals
Once or twice a year, depending on your salt and mold exposure, have your screens professionally cleaned to restore their integrity and ensure any deeply embedded dirt is removed.

Exterior Cleaning for Siding and Roof
DIY Cleaning
Your home’s exterior surfaces, whether they are siding, stone, or stucco, are constantly exposed to humidity, rain, and salt spray. Over time, algae, mold, and dirt can accumulate, detracting from your home’s appearance and potentially causing long-term damage.
Frequency
Pressure wash the exterior of your house every 6-12 months, depending on the severity of the buildup. Homes closer to the ocean or in heavily vegetated areas may need more frequent washing.
How to Clean
Hire a professional pressure-washing service, especially for larger homes or commercial properties, to ensure surfaces are cleaned properly without being damaged by high-pressure water.
Professional Cleaning
Pressure washing can damage surfaces if not done correctly. Hiring a professional ensures that the right pressure and cleaning solutions are used for your home’s material, protecting your property from unnecessary wear and tear.
Frequency for professional
Homes and businesses should schedule professional pressure washing at least once a year. More frequent cleaning may be needed for properties close to the coast or in areas with heavy rainfall.

Dealing with Mold and Mildew
