We are the only company on Oahu utilizing only chemical free methods to restore your home or business. We use the IPC Product line using ultra pure water to protect and refurbish more than just glass. We simply connect our 4 stage water purification system to your water source and it connects to a 3 story telescopic pole with a glass brush on the end. So we gently scrub the tracks and casings around the windows as well. With a rinse, the power is in the Purity and all that is left is water. If it has been a while since your screens have been cleaned we also have a the IPC screen washer II system.
