Here’s some expert advice from the folks at Jeld-Wen, who make windows in the heart of Oregon cabin country.
Choose your day. A dry, overcast summer day is ideal for washing glass. That’s because intense sunlight can cause streaks as the cleaning solution may dry too quickly.
Clean gently. Use a solution of water and baby shampoo or water and vinegar. Mix 1 teaspoon of baby shampoo to 1 gallon of water, or 11/2 cups of vinegar to 1 gallon of water. Wash with a clean, soft cloth or sponge.
Rinse gently. Rinse with clean water. Avoid pressurized sprayers, which can break seals.
Dry promptly. Dry glass surfaces thoroughly with a cloth or wadded up newspaper. Dry window frames and door surfaces with a separate cloth. Be sure to clean up puddles that collect at glass edges, as this can damage window glazing.
Always avoid: power washers, metal tools, razor blades or other objects that can break seals, scratch glass and remove exterior glass coatings.
