Windex

Directions

1. 1
   Combine ammonia, dishwashing soap, and alcohol in a one gallon bottle; then add almost one gallon water to fill the bottle; a few drops blue food coloring may be added to make your homemade Windex look store-bought.
2. 2
   Fill spray bottles with Windex for cleaning interior mirrors and glass surfaces; just use a rag to wipe and shine.
3. 3
   This solution also works well for washing exterior windows. When doing so I like to wash them out of direct sunlight to avoid streaks, then finish the job by polishing each window with wadded up newspaper.
