As a commercial property owner, you’re probably used to shouldering a heap of responsibilities. Luckily, you can lighten that load by outsourcing some duties to efficient, professional teams, such as window cleaning. If you’ve never invested in this commercial cleaning service before, familiarize yourself with the answers to these frequently asked questions.

What You Need to Know About Window Cleaning

How often should windows be cleaned?

Depending on what kind of business or building you own, you may have 20 stories or a mere storefront to clean. No matter how much surface area there is to cover, you should have a commercial cleaning service come by every two weeks. This will ensure the majority of dust, dirt, grime, and droppings won’t become unmanageable or a distraction to employees and customers.

What products are best for cleaning windows?

While you’ll want your windows to be squeaky clean, harsher doesn’t always mean better in terms of cleaning. With the rise in environmental consciousness, many businesses are opting for green cleaning products, which don’t pose a risk to people, animals, or surrounding plant life by releasing toxic chemicals into the air.

How do you avoid streaks?

In addition to using high-quality cleaning products, they should also make sure your windows are completely dry and free of soapy residue, such as by using a large squeegee.

How do you ensure safety when cleaning windows?

If you have a multistory building with a glass exterior, you’ll need your commercial cleaning service to tackle every pane and corner. This usually means the team will need to use climbing equipment or a platform to rise up or repel down the structure. The company you choose should have adequate training and perform routine inspections on this equipment to ensure the safety of their employees, as well as have insurance in case of an accident.
