4. How do I care for my windows?
Cleaning of your windows should be kept to a minimum. If they are dusty, you can use your vacuum to clean them (the little ball attachment) or use a soft brush to wipe them clean. This should be done on a regular basis, probably twice a year.
Never, EVER, SPRAY any cleaning solution on your windows. This includes any commercial products or any homemade products such as ammonia and water. This will cause the patina on the lead to discolor. If your windows are in an area where they can be smudged: This is the time to take your very weak solution of ammonia and warm water, along with a good quality tee shirt material and gently clean only the smudged GLASS area. Spray your cleaning solution on the cloth, not the window. Be careful not to get any solution on the lead, as this will discolor it.
