Windex - cooking recipe

Ingredients

1 1/2 tablespoons ammonia
1 teaspoon liquid dishwashing soap
1 pint rubbing alcohol
water
blue food coloring (optional)

Preparation

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.
Fill spray bottles with Windex for cleaning interior mirrors and glass surfaces; just use a rag to wipe and shine.
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.
