How to clean vinyl windows
Rinse off dirt and debris with clean water.
Vinyl windows can be easily scratched and discolored, so caution is needed when cleaning them. Use fresh, clean water to rinse off any loose particles and dirt from the surface by gently pouring water from a pitcher or wringing it out of a clean wet rag.
Avoid wiping debris-covered windows without rinsing them first. To avoid scratching, you should also remove any rings, bracelets and watches you're wearing before you begin.
