How Often Should Commercial Buildings Get Their Windows Cleaned?

At least every two months, sometimes even more often depending on the industry your business operates in. It’s important for an organization to project a clean and professional image. Your windows are one of the first physical interactions potential and existing customers have with your company. It can often be their first impression.

Most commercial buildings should get all windows (inside and out) cleaned at least every two months. If the building is on multiple floors, the lobby area often used as a reception for guests should be cleaned even more often. This area will be a place where many guests and prospects spend their time making it a priority to be sparkling clean. Glass entrance doors that are used often and can be the first impression people have of your building may need to be cleaned daily.

The industry a company operates in also dictates how often windows should be cleaned. For retail shops and restaurants, their windows act as the first impression to customers and often serve to entice entry. These types of businesses should clean their windows more often at a frequency of every two weeks.

Health facilities such as hospitals, GP practices, medical centres and dentists should also have a much more frequent cleaning schedule for their windows. For these clinical establishments it’s crucial they appear cleanly and well maintained to give patients the confidence they will be cared for in practices that are sanitary, clean, and safe.


What is the Best Way to Clean Windows?

First prepare your glass cleaning solution. We’d recommend creating an effective natural solution that’s environmentally friendly using warm water, lemon juice and vinegar in a spray bottle. Use one part lemon and vinegar to ten parts water. If more glass cleaner is required use the make more using the same proportions of ingredients stated above.

First wipe down the windows using a lint free soft microfibre cloth or a paper towel to remove any dust before you spray your solution. Now spray your natural solution onto your window and use your microfibre cloth to clean. Make sure to quickly dry the window once clean to avoid smears.

Why do Windows Often Look Streaky After Cleaning?

Using glass cleaners that contain ammonia and alcohol can often cause streaks to your windows. These types of solutions can also leave a thin film that could attract additional moisture and dust.

It’s important to dry the windows as quickly as possible to avoid streaks. If streaks do remain, we recommend rinsing the window with clean water to assist in the removal of any of the cleaning solutions that remains on the window that is causing the streak. Ideally you will want to dry the windows once cleaned as quickly as possible as this helps to avoid any smear and smudges.

Windows in commercial buildings frequently have specific glass features or coatings that make cleaning with no streaks a nearly impossible task for staff that aren’t highly specialised. Calling in a professional in these instances is highly recommended.
