For this project you’ll need safety glasses and gloves. Lithium high pressure grease nlgi number two, number three or number four, mild soap and water solution, silicone spray, and a sponge or lint free cloth.
Begin by wiping exterior with cloth dipped in water and mild non-abrasive soap solution. Tip: test in an inconspicuous area of the window to ensure it won’t damage the window. Take the lint free sponge or microfiber cloth and wipe off non-glass materials to ensure completely dry. Spray window cleaner on glass. Wipe off glass cleaner with soft cloth. Wipe any excess cleaner that might have sprayed onto non glass material. After window is clean remove screen from inside and open window fully. Next use wet sponge or cloth with soapy water and wipe down metal operator, lock bar, and hinge components to remove any dirt or grime. Allow hardware to dry completely. When all components are dry, use silicone to lubricate sliding components and rotating joints. Be careful not to get any lubricant on any wood parts as staining may occur. If some lubricant gets on wood, then promptly wipe off. Apply lithium high pressure grease on operator gear. Check weep holes and make sure they are clear of debris. Open and close window a few times to ensure smooth operation and lubrication. Close window and return screen to complete cleaning and lubrication.
