If washing windows is a part of how you make your living, then you're probably pretty efficient at the technique you use. But, before you set out to wash windows, you need to make sure you're using the right tools, and that you're taking care of those tools so they work the way they're supposed to. Using a professional squeegee is the first step, and knowing how to care for your squeegee is of utmost importance.
Use a professional squeegee (not one of those all-in-one, plastic handled squeegees). Visit Denver’s Certified Cleaning Supplies and Equipment. We are a janitorial supplier with professional squeegees. Our professional squeegees use rubber that is designed for durability and wear - you need the best quality rubber for a streak-free window. They are designed with the professional in mind. Certified Cleaning also sells squeegee parts separately (handle, channel and rubber), so you don't need to replace the whole squeegee. Your handle and channel should last for years -- just replace the rubber as needed.
Keep your squeegees in a cool, dark place. Rubber deteriorates in sunlight and dry air. When storing a squeegee, do not let it rest on the rubber - any nicks, abrasions or bending of the rubber will cause streaks. This also goes for setting it down, keep the rubber side up. Clean and dry the squeegee before storing. Change the squeegee rubber often or you'll get frustrated by streaks. A standard rule of thumb is to change it after 15 hours of use. Keep the squeegee clean during use. If the windows are very dirty you may need to remove excess soil or other foreign matter that might be trapped under the rubber.
